Watch for the spur to the left that takes you to the top of the falls. The main trail continues on and hooks up with the San Juan Trail.
Chiquito Falls slows to a trickle in the summer, so the best time to visit is in the spring after the winter rains. There are great places to sit and enjoy your lunch, and you can easily boulder scramble to the bottom of the falls for some great photo ops.
From here, you'll retrace your steps to the trailhead.
