“Ask me about the unique experience I had giving a one-of-a-kind tour for Middle Eastern royalty.” – Saul Singleton

I grew up in Northern Utah, where I was introduced to hiking and backpacking by my Dad. It was there that I developed a true love for the mountains.

I spent my college years hiking the Coastal Mountains of Central California. I began my exploration of the Sierra Nevada Mountains after moving to the Yosemite area in 1984. I found my true calling in 1992 when I became a professional tour guide and hiking guide in Yosemite. My love of the Sierra and experience as a guide allow me to share with you a unique and passionate insight into Yosemite.

The tremendous forces of nature, from thunderstorms and forest fires, to freezing winters, floods and rockslides, will keep Yosemite forever changing. I am still discovering Yosemite, as the dramatic turn of each season brings new color, life and opportunities for exploration. I am always thrilled to invite new people from all walks of life and from all over the world to share my excitement as we discover Yosemite together.

“Ask me about my back country trip out of Cedar Grove, where a bear followed us from camp site to camp site.” – Marsha Eason

I was fortunate enough to grow up with grandparents and parents who worked in, lived in and loved the Sierra Nevada Mountain range.

My grandfather, Herbert E. Wilson, was the author of a book called The Lore and the Lure of Yosemite. He was a naturalist and story teller and participated in the memorable fire falls at Curry Village.

I was born and raised on a cattle ranch in Three Rivers, which sits at the base of Sequoia National Park. I was introduced to the back country of the Sierra by my father, who was a packer in his youth and owner/operator of Horse Corral Pack Station. Vacations were trips to the high country where the days were spent hiking, fly fishing and learning about the many mysteries of Mother Nature.

In 1999, after working in the medical field for 20 years, my husband Wayne and I decided to return to the mountains we grew up in. I have been guiding visitors through the wonder of Yosemite ever since. I love sharing both my experiences of these mountains and the history of the people that were here long before us. The beauty is here for all to see, but it doesn’t mean anything unless you hear the story.

I reside in O’Neals, below the South Gate of Yosemite and on the Scenic Byway. Wayne and I continue to ride and pack into the Sierra Nevada and we’re teaching our grandchildren to love these mountains just as much as we do.

“Ask me about the time a buck with a full rack stuck his head in the door of the bus.”
– Glenn Bennik

I remember my days as a young child when my family frequented Yosemite National Park. My Father taught me to, “glare into the Merced River from Sentinel Bridge, look for trout and capture the reflection of Tissiack (the Miwok name for Half Dome) in the Merced River.” I was so awed by the beauty and geological formations that I took a National Parks course in Junior College.

I recall the night a friend and I drove through a blizzard to ski at Badger Pass. As we rounded a bend between Rail Creek and Chinquapin, we came to an abrupt stop for what we believed was a Gray Timber Wolf. (Since Yosemite has never been wolf habitat, this was most likely a coyote.) We drove around the large (beautiful) creature as he sneered and snarled at our headlights, looking at us as though we were the next meal. What a thrill it was!!

I feel that Yosemite and the area surrounding the Sierra Foothills have given my family (Marsi and Brandon) joy, security and good blessings for the last 15 years.

I strive to share my own personal feelings and memories of Yosemite on my tours. My 12 years of guiding has taken me to the highest elevations of the Sierra, the incredible back country scenery, the majestic Giant Sequoias, Yosemite Valley, Tioga Pass, an occasional fishing adventure and more. Sharing knowledge of this beautiful landscape is exactly what the park’s early protectors desired. Come with me on a sunset journey to the top of the South Rim to witness the stunning Alpenglow and talk about geology.

“Ask me about the time when my guests and I saw a wedding in the sky.” – Grant Bishop

I grew up in Southern California where I lived with my parents. We would come to the Yosemite area in the summers to camp, fish and hike. We loved it so much, the day after my high school graduation we moved here.

I have spent a lot of time hiking in Yosemite as well as in North Fork, Mammoth Pools and on the Scenic Byway. I enjoy reading books about Yosemite and it has been great working with Discover Yosemite because I love to share what I learn with my guests. My favorite area to explore and share is near El Capitan.

“Ask me about the time I saw a Mama Bear and cubs in the Valley” – Koki Bishop

I grew up in a town named Covina in Southern California. My husband and I fell in love with the Mariposa/Oakhurst area while visiting friends who had moved here. We bought a vacation home; then decided to move here full time in 1987.

During the school year I am a school bus driver. When I began driving 89-passenger school buses on the winding Mariposa roads I knew I’d found my niche. I truly enjoy being outdoors every day and getting to know the children. I’ve been driving school buses for 18 years now. I am very thankful to live and work in such a beautiful environment, with clear skies and lots of trees.

I also love having the opportunity to drive and give tours in the summer when the kids are on summer break. Even though I’m still working, I feel like I’m on vacation too. I especially enjoy seeing my guests’ excitement when they encounter the incredible beauty of Yosemite.

“Ask me about the squirrel friend I made near Vernal Fall when I was seven!”- Ralph Fairfield

My mother was a kindergarten teacher who had the summers off and would take me to Yosemite for weeks at a time. I grew up riding my bicycle throughout the valley, picnicking at Fern Spring, climbing in and around the “Indian Caves,” camping by and floating down the Merced River, hiking to Half Dome, listening to the wind in the trees and watching the Firefall.

I spent my 21st birthday in the park, and as I gazed at the beauty of Half Dome, Glacier Point and the Royal Arches, decided then and there that I wanted to be a Ranger. This was May, and I went to the administration building to request an employment application only to learn that they weren’t taking any more applications until January. I then went to the State of California, signed up to be a State Park Ranger and enjoyed 30 years with the California State Park system. My wife and I retired near the park, so now I have the privilege of visiting Yosemite on a regular basis and sharing its beauty with people from throughout the country and around the world!

I was raised in Florida where my dad was a biology professor and outdoorsman who instilled in me a reverence and respect for all things natural. From the age of 8, I spent many summers with my family hiking and camping in the Blueridge Mountains of North Carolina and Tennessee. We did a tour of the western states in the summer of 1968 when I was 14 years old. Of all the parks we visited that summer, Yosemite had the most profound and lasting impression on me. We were among the last group of visitors to the park who were ever allowed to drive our car through the Mariposa Grove and the Wawona Tunnel Tree the before it fell the following winter.

My impression of the park from that early age was my impetus to return in 1999. I worked in the park as a shuttle driver in Wawona and Yosemite Valley and I drove tram tours through the Mariposa Grove of Giant Sequoias until the trams were discontinued after the 2014 season. I have a deep and abiding love for Yosemite and its history and I love to share my passion with our visitors to the park.

My career in Yosemite began in 1974 when I was hired by the National Park Service to be a member of the horse mounted patrol. I lived in Yosemite Valley for three years and in late 1976 and moved to Wawona where I was a Ranger until 2000. I then switched into the Maintenance Department where I worked on the road maintenance crew until I retired in Dec. 2014.

Working for the National Park Service and living in the park gave me an opportunity to hike, ride, ski, fish, raft, and occasionally fly over the park on fires, search and rescues, med flights, etc.. I got to see the park under all sorts of conditions; sunrise, sunset, crystal clear starry nights, flooding rivers, snowstorms, etc.. Can you imagine growing up in Yosemite like our two children did? They got to walk out our door and hike, swim in the river or sit by the fire and watch a snow storm, then go sled down the hill.

I was born and raised on a farm not far from the western slopes of the Sierra Nevada. In my youth I enjoyed backpacking trips as an Explorer Scout. My love of the high country as a teen was the beginning of a lifetime of learning about and experiencing Yosemite and the Sierras. Among many highlights was seeing the Firefall off of Glacier Point. As a Telephone Lineman I climbed trees to maintain lines into Cedar Grove in Kings Canyon National Park.

My family enjoys living in this part of the country and having hiking trails in our own back yard. Of all the National parks, Yosemite is my favorite. Fresh air, flowing streams, majestic falls, wildlife, beautiful vegetation and unique rock formations captivate the senses.

“Ask me about the time I walked on Tenaya Lake with my wife on New Year’s Day, 2012.” – Lynn Fullmer

I was born and raised in Fresno. I enjoyed many camping and fishing adventures to various sites in the Sierra National Forest adjacent to Yosemite. Rides on the Yosemite Mountain Sugar Pine Railroad intrigued me and I even attempted to replicate the setting in a HO scale model railroad at home. Many trips were made to Yosemite Valley to see the waterfalls.

In 1979 I moved to the Oakhurst area just outside the South Entrance to Yosemite National Park and operated an appliance repair business with my dad that my son now owns. Over the years there have been many more trips to Yosemite with friends and family. Everything is always in the same place but everything is always just a little different. Regardless of the season, the beauty, grandeur, and awesomeness of the rock formations and waterfalls never disappoint!

I’m looking forward to sharing the never ending beauty of Yosemite National Park with you on my next tour. From the Giant Sequoias to the mighty falls, from Glacier Point to El Capitan and of course, the picturesque Half Dome! Hope to see you soon!

“Ask me about the Bear Cave.” – Steve Riley

I grew up an “army brat” and lived all over the world – from Hawaii to Germany and many places in between. I discovered Yosemite after college, and loved it so much I moved there. While there, I got married and my wife and I had our two daughters as we lived in the Valley.

I also wrote a children’s book about a little raccoon that lived under my porch in Yosemite and that little book launched a new career. So now I am the author and illustrator of the Little Ty Cooney National Wonders Series, and I get to travel all over the country and teach kids about writing and illustrating and the Parks I love so much. While I am not traveling I love to take tours into Yosemite -it makes the park new all over again to show it off to folks who are less familiar with it than I am.

I started driving shuttle buses in Yosemite in 1990, taking people to Tuolumne Meadows and all through the Park. Although my commercial bus driving career started with Greyhound, once I drove in Yosemite I knew there was no turning back. That is when I made my home in Mariposa.

I had the wonderful experience of living in a tent cabin at the stables in Yosemite Valley and would spend my evenings at camp fires with backpackers as they would tell their stories of Yosemite’s 800 miles of trail. I fell in love with all the wonders in the Park.

Every day in Yosemite is exciting to me. I always find something new, even to this day, 24 years later. That is why I joined the guides at Discover Yosemite. I love to share the things I learn about Yosemite. Like, just not long ago, I discovered that there is a 100 foot tall ponderosa pine tree that is a third of the way up the face of El Capitan.

I was born in Los Angeles and grew up in Encino in the San Fernando Valley. My family and I traveled and camped all over the western United States while I was growing up, but I always loved Yosemite and the Sierra the most.

In 1961, when I was 12 years old, I started rock climbing in Southern California. I spent my first summer climbing in Yosemite in 1965 and in 1966 I moved to Yosemite full time. I have lived, climbed and back packed in Yosemite and the Sierra ever since. I am married and have two grown children that still consider Yosemite home.

I started guiding rock climbing, hiking, back country and natural history tours in 1970 and have been doing it ever since. Meeting people from all over the world and all walks of life and sharing Yosemite with them is a very important part of my life. People are the key to preservation.

Have you ever hiked along a mountain trail early on a crisp April morning, hundreds of feet above a river rushing through the rocky canyon below, just to catch a glimpse of springtime dew drops gracing the delicate petals of a wildflower?

Or when was the last time you camped among the pines to watch the moon rise above lonely, rugged mountain peaks? Can you picture yourself leaning back against a rock, to do nothing for the next hour except close your eyes and listen to the great symphony of nature?

I have lived in the Yosemite area for thirty-one years, and some of my most vivid memories come from times my family and I spent in our beautiful, majestic Yosemite National Park– hiking the waterfalls, picnicking in grassy meadows, and breathing in the clean air and refreshing smells of the great outdoors.

These memories have given me an appreciation of Yosemite that I love sharing with others. With ten years experience in customer service and the tourism industries, I can’t wait to take your call and make your reservation for a trip you’ll never forget as you DISCOVER YOSEMITE.

I have been fortunate enough to be raised in the Sierra Nevada Mountains just a bus ride away from Yosemite National Park. As the daughter of a tour company founder I had the pleasure of spending my summers and school vacations in Yosemite. Even as a child the sights were awe-inspiring. I was able to learn many facts about Yosemite and different clues to remember these facts.

I learned how to ski in the park at Badger Pass, starting on Turtle, the bunny slope, at age 6 and racing past my mother not long after that. P.E. classes throughout grammar school included ski lessons at Badger once a week. I also have great memories of field trips to Yosemite and doing many school projects about the park. I have chosen to stay in this area to raise my son in the same surroundings that I love so much.

As a graphic designer I was given the opportunity to design the website for this company. It has brought back many memories from my childhood. I am excited to get back on a tour and Discover Yosemite once again. I will also be working the reservation desk and will be happy to answer any questions you may have.

For years I dreamed of getting to Yosemite, and when I did I ended up staying for 10 years. I am still amazed that I managed not to drive off the road when I got my first view of Yosemite Valley. I have never lost my love for this truly awesome place. I began giving tours of Yosemite shortly after my arrival there and continued to do so until I moved to Northern New Mexico, my heart’s home.

I continued working as a tour guide in Santa Fe. At present I am a group leader/tour guide/teacher for Elderhostel. I hosted a radio interview program on the arts and culture of New Mexico for two and a half years and have been a freelance writer since 2004. My work can be found in the Special Issues of The Santa Fe New Mexican and the New Mexico Magazine. I have won national awards for both my writing and my radio interviews.

I was thrilled when Dee Ann asked if I’d write the text for this website. I was glad to have a chance to work with her again and to write about one of the places I love most on this earth. This project has brought back many lovely memories. So when Dee Ann asked if I might be interested in being a guest guide, I jumped at the chance to once again share this special place with visitors from all over the world.
