Be early or be crowded.
One can start the run to the Ben Johnson Trail through Muir Woods National Monument by either the Redwood Creek Trail
or the Hillside Trail
. The steep climb to the ridge snakes through the redwood forest and up through the fog-line onto the grassland and shrub-scaped top of Mount Tamalpais. This trail is well shaded on a mostly soft pathway. However, expect to spend some energy on this mile climb. Ben Johnson is a great escape from the crowds below and can be utilized to complete a much longer loop.
