Gentry did an amazing on the hike, keeping us informed, volunteering much information (she’s a geologist, but knows as much about food, animals, urban issues etc), managing a group with different skill levels, picking spots fir pictures. She’s fun, lively, pays attention to the whole group. It was a perfect way to do some hiking while visiting, without the hassle of getting a car, figuring out steps, getting a permit. I highly recommend the tour!
