This trail is only 1 mile long, but it can be combined with other bike routes in Marin County to give a full day of riding. See the Tiburon trail, and the Mill Valley-Sausalito trail both on this website.
The best parts of this trail are the views of Mt Tamalpias, the canopy of large trees, and the wetlands.
When going north be sure to turn to the right at Baltimore Ave, there is another bike trail that continues North, towards San Anselmo.
Shortly after this turn look for an historic orange building marked "Northwestern Pacific Railroad Company, Baltimore Park Substation". Before WW2, Marin County had a network of electric railroads, and this was part of the electrical system. The tracks in this section actually had four rails. Two for the wide guage, a third rail to accomodate the narrow gauge trains, and a fourth rail to suppy power.
If you want to connect to Mill Valley or Tiburon, be sure to carry a detailed mike map for Marin County, because the connections can be tricky. Read my review for the Mill Valley-Sausalito Trail for comments about the two routes between Corte Madera and Mill Valley.
According to marinbike.org, work is almost completed to reopen the Cal Hill Tunnel between Larkspur and San Rafael. This will make an excellent connection to this trail. As of March 2010, the tunnel upgrades are almost complete; by the time you read this the tunnel will hopefully be open. The Marin Bicycle Coalition is also advocting reopening the rail tunnel between Corte Madera and Mill Valley, which would connect this trail directly to the Mill Valley trail. If someday this tunnel is reopened, it would create a level, off-street bike path all the way from Sausalito to San Rafael.
