Bon Tempe Lake: Forest Lake Hiking Loop and Watershed Serenity
In the Mount Tamalpais Watershed near Fairfax, Bon Tempe Lake offers a scenic reservoir loop through shaded forest with water views. Managed by Marin Water, this peaceful spot provides easy hiking amid redwoods and oaks; ideal for families and nature immersion.
A Shaded Reservoir and Woodland Haven
Bon Tempe blends open lake waters with surrounding mixed evergreen/redwood forests, riparian edges, and hills. The loop reveals forested shores, distant peaks, and birdlife; seasonal wildflowers and amphibians thrive in the protected watershed.
Adventure With a Conservation Conscience
The easy-moderate Bon Tempe Lake Loop (4.1 miles, minimal gain) circles the reservoir via flat paths with shade; extend to Lagunitas or Alpine Lakes for longer routes. Fishing paused (invasive golden mussel precaution).
Access is thoughtful: parking fees (cash/credit at lot), sunrise to sunset, pack out waste, leashed dogs ok. No established trail around some reservoirs; stay on designated paths.
Bon Tempe Lake delivers Marin forest lake hiking loop in tranquil beauty. For walkers seeking shaded water views and gentle trails, the circuit repays simple enjoyment; a serene watershed escape.
