Seth Pettit, Owner and Guide

AMGA Apprentice Rock Guide

AMGA Certified Rock Instructor

AMGA Certified Single Pitch Instructor

Wilderness First Responder


Seth has been a Joshua Tree resident since the Fall of 2003 to remain close to the National Park and it's exceptional rock climbing. His climbing career began about 12 years ago while living in Jackson Hole, WY. Obsessed from the beginning, he started to develop his skill set and gain experience the way good climbers do, by rock climbing!

By 2008 he had visited most of the famous climbing areas of the US and earned his first professional certification with the American Mountain Guides Association (AMGA). Seth began his guiding career the same year, as a Trip Leader for Indiana Universities' Outdoor Adventures.

In 2010 he received an outdoor recreation and natural resource management degree from I.U. with a focus on rock climbing (yes, you can get a university degree for rock climbing!). ​

In 2013, following an intensive training period and subsequent 6-day exam, he was awarded the AMGA Rock Instructor Certification. This certification allows him to guide pretty much anything you want to climb in the park!

Today, Seth has worked with thousands of clients, from five years old to seventy-five years old through ten different organizations based in seven states.


Here is a list of the organizations he has worked for:

Seneca Rocks Climbing School (WV), Rock About (TX), Inner Passage (WA), Joshua Tree Uprising Adventure Guides (CA), The Boojum Institute (CA), Atlantic Climbing School (ME), Wilderness Outings (CA), Falling Creek Camp (NC), SWS Guides (CA), Indiana Universities Outdoor Adventures (IN)

This breadth of experience in conjunction with his commitment to the American Mountain Guides Association’s standards and certifications is what sets Seth and Mojave Guides apart from his competitors.

Our Guests often reach out to us here in the office to ask about tipping standards within the guiding industry. If your guide has provided an exceptional experience while keeping you and your friends/family safe in a very busy park, a gesture of your gratitude would be well received. An average tip for a Half or Full day of climbing would be anywhere from $20 and $100. This typically amounts to less than, or equal to, the standard 20% we leave the waitstaff on a daily basis. Thank you for your support of the professional guiding industry and it's up and coming stars here in Joshua Tree :)
