Aw, Liz Weber(owner of Muir Valley) was ADORABLE! She was there when we showed up the 2nd day, map in hand, and directed us so that we knew what to do in an emergency. She even had some recommendations for a dryer climb, since the weather the day before had been a little wonky. On top of that, all the climbers we met were perfectly respectful. It was a carry-in, carry-out preserve and thankfully the only ‘garbage’ I saw on the ground was a blanket of leaves everywhere — which was perfectly oh-so-fall. The walls, as Liz mentioned, were incredible, even in the rain(not all, but some), since there were walls with overhangs that blocked out even the nastiest of storms. There was a bathroom in the parking lot and an outhouse closer to where we climbed. The trails were well marked and a quick Google search would bring you information about every single route and its ratings that you could find in the preserve. We loved this place, the slabs, the crags, the well-worn muddy paths, the chimney climbs, the practice walls — loved it all. I can’t wait to bring back a larger group of climbers here! Also things to note: no admission charge — this preserve is run and operated through donations . If you are climbing, be sure to fill out the electronic waiver before you go!
