Lake Loop: Hike on Bon Tempe Lake in Marin
Scenic and easy loop around Bon Tempe Lake on March 7
This is a gorgeous 4.1 mile ramble which is flat and takes you all the way around Bon Tempe Lake, hugging its shores the entire way. Bon Tempe Lake itself provides a wide variety of scenery. The north side features an open area, while the remainder of the shoreline features trails that travel through wooded areas. The dam has a great view of both Bon Tempe Lake, Mount Tamalpais, Alpine Lake, and the surrounding mountains. It takes about 1.5 hours at an easy pace and because it's flat is suitable for kids. There can be ticks, so spray your socks before you leave home.
Enter "Bon Tempe Lake Trailhead" into your GPS and you'll be driving through Fairfax. There is plenty of parking, but they will charge $8 per vehicle at the automated pay station upon entering the watershe parking area.
