The Lagunitas, Bon Tempe, and Alpine Lakes via Lakeview and Cataract Loop offers a challenging and diverse hiking experience through the Mount Tamalpais Watershed. You'll traverse varied terrain, from tranquil lakeside paths around Lagunitas and Bon Tempe Lakes to the dramatic, redwood-lined gully of the Cataract Trail, famous for its cascading waterfalls.

Parking can fill up quickly, especially on weekends, so arriving early is recommended.

Fern Creek Trail is an excellent trail – scenic views, technical underfoot, loose at times, mind your head on low branches. Close to the bottom there have been caribou land slips and tree falls over the years that have meant the trail is rerouted up and over ever so slightly. Absolutely adore this trail.

Often busy on weekends, this is a great spot to take moment before/after summiting Mt Tam. There are spigots to fill up water and bathrooms that are open during park hours. The parking lot is very close for those that drive up. There is access to MANY trails for those on foot/bike.
