According to Park materials, large numbers of people, both Indians engaging in tribal functions and interested visitors, regularly gather here, but when we stayed in the campground most of the sites were unoccupied, and we were alone in the Indian village that has been reconstructed in the golden meadow surrounding the grinding rocks. It is a sacred place; the Miwok Indians ground acorns and other seeds here for thousands of years, and though now wooden rails prevent visitors from touching any of the 1,185 mortar holes in the two outcroppings of marbleized limestone, it is easy to imagine clusters of women processing baskets of acorns gathered from the giant trees where now only noisy woodpeckers are at work.

You're at 2400 feet here, which means summer days may be hot. The trails have not been planned for accessibility, and many are difficult or unusable, but one paved path leads across the meadow, and paths between facilities are generally hard and smooth. Some routes across the meadow are uncomfortably rough, but may be worth the trouble.

Trail Overview:

This is a self guided nature trail, quite comfortable at first, but becoming narrower, with rocks and roots eventually making it impassible well before the 0.5 mile loop can be completed. Still it is worth a visit. The trail guide available to be borrowed at the roundhouse describes the ethnobotany of the area and identifies some of the plants that were used by the Miwok.

Accessibility Notes: Since our visit, according to state parks website there is now an accessible trail. The North Trail features an accessible segment for 0.6 mile. The accessible segment begins at the main parking area near the amphitheater and ends at a seating area located near the junction of the North Trail and the Loop Trail. The accessible segment includes a trestle bridge crossing over Else Creek, views of the Historic Farmhouse, and a hike through a mixed hardwood forest.
