Bay Area Hiker: Equestrians Horse HillWatch Your Step!

Equestrians, in my opinion, tend to be the most careful of all trail users. They need to be cautious, to protect the safety of their horses, and themselves. The only issue I have with equestrians is the damage their horses do to the trails. Many preserves close certain trails during winter and early spring months to lessen the impact of horse hooves on muddy trails. Still, horses do more damage to the trails than any other use group. Not to mention the unpleasant density of  horse poop on well-ridden trails. It's only fair to allow equestrians ample access to multi-use trails.

If you dislike horses or any of the issues mentioned above, you may want to avoid the following trails/trailheads:
Alto Bowl Open Space Preserve, MCOSD, Marin County (preserve includes Horse Hill)
Bear Valley Trailhead, Point Reyes National Seashore, NPS, Marin County (heavy horse use)
