The Hoo-Koo-E-Koo Fire Road skirts the east side of Mount Tamalpais; its winding route features stunning scenic views of San Francisco Bay and the Marin peninsula. Some say the trail was named for a band of Coast Miwok Indians that lived nearby or because of Miwok middens discovered in the area.

Blithedale Ridge Fire Road runs Northwest-to-Southeast from Eldridge Grade (via a short Indian Fire Rd connection) on the east side of Mt Tamalpais to northern Mill Valley, following a mostly forested ridge with steep ups and downs. It connects with Corte Madera Ridge Fire Road to continue further east and drop down trough the Camino Alto OSP to the terminus of the Mill Valley-Sausalito Bike Trail. This is a segment of a longer dirtroad tour https://www.komoot.com/tour/13627077 between Point Reyes and San Francisco.

An easier šµ loop in Mt Tamalpais Watershed: It climbs gradually on Shaver Grade fire road from the Natalie Coffin Green Park parking lot in Ross below Phoenix Lake to the intersection with Filter Road to Lake Lagunitas, circles the lake and climbs a little south of Pilot Knob, turns right south on Eldridge Grade and then offers a turn left onto Indian Fire Road which soon swings north and back down along a pronounced ridge (see photo) toward Phoenix Lake. Unfortunately Indian Fire Road connects to residential streets and very short connector trails that are pedestrian-only before continuing again as multi-use trails back to the parking lot. This track here shows the politically correct return via quiet Ross residential streets to the parking lot. See šµ Tour https://www.komoot.de/tour/9831707 for highlighted segments and labeled photos. For a similar length yet slightly more challenging loop with 4 lakes via Rocky Ridge fire road try https://www.komoot.de/tour/9817832 On every tour š Gopher snakes crossed the trails in front of my bike. They move slow so be careful not to roll over them accidentally, particularly when biking down the sweet descents. š NOT Dangerous (Non-poisonous) š Gopher Snakes do NOT have venom dangerous to humans One of the most commonly seen snakes in California. Primarily active during the day, and after sundown on hot days. Often crawling across trails and roads, and around human dwellings or backyards, attracted to rodents which thrive in such areas. Unfortunately, this harmless and beneficial species is often killed out of fear that it is dangerous or a rattlesnake. http://www.californiaherps.com/identification/snakesid/gophersnakes.id.html

Great hiking and mountain biking on this gravel fire road in Mt Tamalpais watershed. It initially climbs south from the intersection with Eldridge Grade Fire Road, then turns north and descends along a pronounced ridgeline forming the eastern boundary of the Mt Tam watershed and the Ross residential area. At the end there are hikers-only pedestrian trails connecting back to the parking lot; on bikes the return to the parking lot is via residential streets. For a sweet 2 hour mountain bike loop via Lake Lagunitas involving this trail segment check out https://www.komoot.de/tour/9831707 For a more challenging loop with 4 lakes via Bon Tempe dam and Rocky Ridge fire road try https://www.komoot.de/highlight/153264 See šµ Tour https://www.komoot.de/tour/9831707 and https://www.komoot.de/tour/9817832 for highlighted segments and labeled photos To go up to the summit take Eldridge Grade https://www.komoot.de/highlight/215025 , or take Hoo-Koo-E-Koo https://www.komoot.de/highlight/215026 to Old Railroad Grade https://www.komoot.de/highlight/215016 for a more gradual ascent to the summit.
