Topanga Canyon Time Tunnel

Tucked away in this iconic canyon is a storm drain that acts as a portal to a mystical grotto that is fed by springs running through Topanga. The tunnel is 20 feet down the road from the "SLIPPERY WHEN WET" road sign on the west side of Topanga Canyon Blvd. You might be ticketed for unsafe parking on these windy roads. Other visitors recommend parking by Topanga Lumber and walking the quarter mile to the road sign.
