Despite being basically on the way to a much more renowned climbing destination (Squamish and the Sea to Sky Corridor), Lighthouse Park is definitely worth the detour. Situated just west among the extravagant homes of West Vancouver, this area consists mostly of seacliffe-style climbing and bouldering on featured seaside granite.
The most popular climbing routes are off of Juniper Point. These routes can be crowded (especially near sunset on weekends), however much of the bouldering and other cragging areas see little crowds.
UPDATE: For first ascentionists, no routes may be laid (i.e cleaned and bolted) in areas of significant vegetation. Consult Vancouver Parks for more information.
Follow the signs to Lighthouse Park along Marine Drive in North Vanvouer and turn south onto Beacon Lane. Park at the parking lot and follow a gated trail on the right. It winds around and if you take the correct turns you will get to the cliff in about 10 minutes.
