Our family thoroughly enjoyed our day, hiking with John through the back country of the Sierra Nevada. We saw amazing sights, swam in lakes, ate great food and to top it off even saw a bear (though not sure if that is repeatable on every hike). We would thoroughly recommend John for hikes in Yosemite region. We found John to... More

We (a French couple) went to Yosemite for a 3-day trip with John and his lovely dog Parker, in June 2014. In one word, it was AWESOME! - A hiking trip "à la carte" Before the trip, John asked us what were our expectations and our hiking skills. Based on that, he offered us a fully bespoke trip, perfectly fitting... More

We went with Martin to a 3 day trip to Ostrander lake June 2014 and had a fantastic experience. Three teens from age 11 to 15 backpacked for the first time and also had a great time. The cooking was inventive and delicious and all of the equipment was new or like-new high end brands. Highly recommended.

Being a trip facilitator myself, I've NEVER hired a guide before. My friend Marcia who also is an avid traveler and hiker suggested we hire guides and to my dismay, it was AWESOME! John & Martin were experienced, knowledgeable but most importantly, genuinely great people to spend time with in the great outdoors. Their love of the Sierra's and nature... More

My husband and I and another younger friend decided to go with a guide service that would help us take all the guesswork and angst out of backpacking in the Sierras. Because it was very early in the season, they could figure out where to go, They were very accommodating to our needs as "older" backpackers. (Late seventies). It was... More

From the moment we met Martin he said that he would make this the trip we wanted it to be. We spent hours tooling around taking photos on a bright sunny Sunday. Martin has many interesting experiences and knowledge that he graciously shares with you as his guest. We did a little hiking, he was very patient as we hiked... More

We booked a guided day trip with John to learn more about the area and to get off the beaten path. John exceeded our expectations on all accounts. He is extremely knowledgeable about the wildlife, geography and history of Yosemite and the Sierra Nevada mountains. He was accommodating to our level of ability in hiking, and intuitively knew when we... More

John took us on a guided backpacking trip into the Sierra's for three days and we could not have had a better time. On the drive out, he gave us so much background about the park and the area we were going to be hiking in. He was so prepared and had great gear for us to use. We ended... More

We had an outstanding day with John (and his dog Parker) which was perfect for our 3 teenage girls, my wife and I.
