Off Road Bicycling

Horseback riders have right-of-way on the trails with hikers coming second. Bicyclists must yield to both of these trail user groups. Be aware that many horses are easily spooked when approached from behind. Reduce your speed when approaching horses or hikers. When approaching from behind, announce your presence. Stop on the downhill side of the trail while horses pass. The speed limit on all trails, even when headed downhill, is 15 mph. Be courteous. If trails are dry and dusty, slow down even more so as not to leave hikers in a cloud of dust.

The maximum number of bicyclists in any one group is 10. Larger groups of cyclists will have to divide into groups no larger than 10. This size restriction is necessary for the safety of cyclists using public roadways and authorized trails within the Park. These roadways and trails are narrow and winding and will not safely accommodate large numbers of bicyclists.

Caution

Loose dirt and gravel cover many of the trails. This slick surface can be difficult to maneuver in and can make for easy slide outs. The loose dirt can also hide potholes. These technical riding surfaces challenge even the most experienced bikers. We recommend always wearing a helmet, a long-sleeved shirt and long pants.

Road Bicycling

Marin County is a popular destination for bicycling. It is recommended that bicyclists dress in clothing that helps them be visible to motorists and be aware that many of the roads in West Marin are windy and have minimal shoulders.

Carry plenty of water and snacks. Eat before you are hungry and drink water before you are thirsty. Prepare for weather changes by wearing and bringing layers.
