Hiking
Embark on the Peters Creek Loop, a difficult hike spanning 11.8 miles (19.0 km) with a significant elevation gain of 1987 feet (606 metres). You can expect to spend around 5 hours and 41 minutes exploring this remote redwood forest. The trail offers a deep sense of solitude as it winds through ancient groves, where some trees are estimated to be 1,200 years old. Along sections like the Bear Creek Trail, you will encounter lush greenery, small blue wildflowers, and redwood sorrel, creating a wild and ancient atmosphere.
Before you set out, be aware that the trail can be overgrown with poison oak and thistle, especially after winter rains, so wearing long pants is a good idea. You will also encounter two creek crossings that do not have footbridges, meaning you will need to step carefully on wet stones. Given the steep and potentially slippery sections, particularly when descending into and climbing out of the canyon, sturdy hiking shoes are highly recommended for your safety and comfort. Plan your visit to allow ample daylight for the full duration of the hike.
This route stands out for its unique sense of solitude, guiding you through seldom-seen areas of Portola Redwoods State Park. It provides an opportunity to immerse yourself in a dense redwood forest, home to some of the region's oldest and tallest trees. The trail's remote feel and ancient atmosphere make it a distinctive choice for hikers seeking a challenging and immersive natural experience away from more crowded paths.
