Las Trampas Regional Wilderness

Las Trampas Regional Wilderness is a large park spanning over 5,000 acres in Contra Costa County with two major ridges running through the landscape. The terrain features oak woodlands and chaparral areas connected by numerous trails at varying elevations.

The area received its name from Spanish settlers who used the word Trampas to describe the traditional hunting methods in this region. The landscape was shaped by human use over centuries before being designated as a protected wilderness area.

The name Las Trampas comes from Spanish colonial times and refers to traditional hunting practices that took place in this region. Today, the area connects nature with literary heritage through its proximity to the Eugene O'Neill National Historic Site.

Visitors should bring plenty of water since drinking facilities are limited and not always available year-round. Sturdy hiking boots are important for handling the varied elevations and different trail conditions throughout the park.

The exposed rock formations in the park contain layers of marine fossils that reveal traces of ancient shorelines. These geological layers show that this region was once submerged beneath ocean water.
