Tips from the Community

Christopher
November 5, 2023, Alpine Lake

Don't be fooled, 'Alpine Lake' is the name of this body of water, but the fact that it is an alpine lake is highly debatably at a lowly 768 feet. Irregardless, the views are still nice. You can look but not touch as there is no swimming or boating allowed in the lake.

The view from the start of this trail is amazing with the rolling hills leading into the mountains. There is lush greenery as far as the eye can see as Mount Tamalpais Watershed meets the Cascade Canyon Preserve.

Carson Falls is a multi-tier waterfall that flows through Little Carson Creek in the Mount Tamalpais Watershed. Just four miles southwest of Fairfax, it is easy to get to and well signed.

Very strenuous and technical hike but beautiful. Dog friendly.

Rising slightly above the summit of Fairfax-Bolinas Road the views from Azalea Hill are mostly to the east. Mt Tamalpais dominates the view to the south.

Crossing this saddle is a good excuse for a stop to take in the views, and maybe even hike down to Carson Falls from the nearby trailhead
