Tiburon Uplands Nature Preserve in Tiburon, CA, offers a short wooded hiking loop along Upland Trail. An unmarked trail connects this loop to trails in Old St Hilary's Open Space Preserve. Combining trails in both preserves, longer routes up to three miles long may be formed.

Best time to visit: Any time of the year. The preserve is wooded. In spring, you would see a few wildflowers.

Notes: Tiburon Uplands and Old St Hilary's (see trail map) are connected by a well maintained unnamed trail that is not drawn on the official trail map.
