Although roads approach the park from the west through Soledad and from the east through empty lands south of Hollister, the roads do not connect in the park.
Most of the developed areas are on the east side of the park.

Several trails have been developed for day hikers, some of which are strenuous.
Primarily in March and April, a wide variety of wildflowers is on display, except in years of extreme drought.
The trails provide views of the surrounding hills and valleys on clear days.
The San Andreas Fault is visible from some vantages along the trails.
The park includes a well-known hiking portion known among enthusiasts simply as "The Pig Fence".
This portion of South Wilderness Trail is a challenging stretch of strenuous hiking that at times requires use of the fence, erected to prevent feral pigs from entering the park, to help oneself to climb the steeply pitched trail.
Other trails include lush wildflower-accented views along flat stream beds, trails that bring one into beautiful caves, and trails that involve high vistas of the Pinnacle formations.
The park is popular with advanced rock climbers due to the many difficult and challenging climbs.

The caves at Pinnacles are talus caves, formed when steep, narrow canyons were filled with boulders, leaving passages between the larger rocks.
 Bear Gulch Cave on the east side of the park and Balconies Cave on the west side are seasonally open to visitors.
Trails lead to and through both caves.
 These caves house breeding colonies for Townsend's big-eared bat and are closed during pupping season.
The caves may be flooded at times of high water.
 The National Park Service maintains a webpage showing the status of the caves.

Camping facilities are available on the east side in the Pinnacles Campground.

Climbing is also popular at Pinnacles National Park.
The park is home to a variety of bouldering, single-pitch, and multi-pitch routes.
Rock quality, volcanic breccia, can break while climbing.
