Fossils & Missiles

Las Trampas translates to “the snares”, and for good reason – this park is known for its dramatic inclines and fine gravely topsoil, so step carefully! It’s ruggedness makes it less traveled, which lends itself perfectly to a quiet adventure across the 5342 acres of wilderness. Some trails boast as much as 900 ft of elevation gain, making Las Trampas a fantastic place to get accustomed to the hills of the East Bay. If you choose to climb one of the two hilly ridges in the park, you may be so lucky as to come upon a fossil from the Miocene era . There have been a wide variety of fossils discovered in the park – to include parts of a mastodon and a gomphotherium.

During the Cold War, the area was used as a nike missile site, but nowadays it is home to countless species of local flora and fauna, across multiple biomes. To the trained geologist, the area has more questions than it does answers . To the trained hiker, the area offers established trails and hill scrambling. Las Trampas is truly a hidden gem of the East Bay.
