Elizabeth Biron

I became a Guide because I believe in the power of mentorship and making a difference to others’ experience in the outdoors (as so many have done for me!). I like to do this by creating the most supportive and comfortable trip possible, while also helping break through physical and mental barriers. 

I moved to California from the east coast in 2016, when I was predominantly rock climbing year-round. After experiencing the extraordinary mountains of the Sierra Nevada Range, I decided to make Mammoth Lakes my home. I have since lived in and explored many other mountains, trails and countries- including Australia, China, Thailand, Switzerland, France, Italy and Mexico.

I guide many trails here in the High Sierra, including more technical mountains such as the Mountaineers Route of Mt. Whitney. In my spare time you can find me rock climbing, trail running, peak bagging and snowboarding- the High Sierra has it all!
