Step into a verdant, almost magical world on the Baltimore Canyon and Dawn Falls Loop, a moderate 5.6-mile (9.0 km) hike that feels like a deep dive into nature.

Planning your visit means timing it right; for the most impressive waterfall flow, aim for late winter or early spring. Be ready for potentially muddy sections on the twisty, narrow path to Dawn Falls, and consider bringing trekking poles for the steeper parts. Parking at the trailhead can be tight due to its convenient location near Larkspur, so an early start is a smart move to secure a spot.
