About LOWER THUMB ROCK
A short distance from Pe¿¿a Blanca Lake, Lower Thumb picnic site contains six picnic pods nestled in a mini canyon. Some of the picnic tables are shaded by beautiful mature trees. A walking path connects the picnic sites and makes for a nice digestive stroll following a family meal cooked using one of the onsite grills. The closest vault restroom is located at Upper Thumb Rock Picnic Area.
