I CANNOT SAY ENOUGH GOOD THINGS ABOUT GREG!!! Our hike with Greg was amazing. Greg was among the most knowledgeable, professional and organized guides we ever have had--and we have worked with many. He curated a hike that exactly met our criteria. He was well prepared and made us feel totally confident. He was also extremely knowledgeable about what we were seeing and shared that knowledge. And, he was just a nice and personable person. If you are looking for a guide to help lead your group on a hike, Greg is absolutely the best choice you could make. I cannot say enough good things. Among our best guides ever.
