Did the Indian Trail Loop today, best described in Bay Area Hiker (perfect trail description and directions):
using a map from Marin Open Space District:
Met really nice people along the way - horseback riders, cyclists. While the day was hot, trail was shaded and well maintained. Really enjoyed this loop, along with its views and escape from urban ambient noise. Just the noise of birds, lizards and the occasional deer.
