Overview

An easy out and back ride up the Arroyo from the JPL parking lot. This is a good beginner ride.

Need to Know

This trail is very popular with hikers, campers, and equestrians. Observe trail etiquette (yield to hikers, stop for equestrians) and use a bell.

There are several stream crossings, all usually rideable.

Description

Park at the Windsor Lot overlooking Hahamonga Watershed Park and the Jet Propulsion Lab. Head north past the Fire Danger sign and along the paved access road. Follow signs for the Gabrielino, staying to the left. This trail meanders up the Arroyo past the Gould Mesa Campground and a couple of picnic areas. This section of the Gabrielino Trail (NRT) is considered easy compared to other routes and trails in the area because it is relatively flat, the trail stays fairly wide, and there is little height exposure. There are a few sandy spots and some short rocky sections.

At the Paul Little picnic area, the Gabrielino Trail (NRT) splits off to the right and climbs the canyon wall in a series of steep, exposed switchbacks, eventually proceeding above the USFS debris dam and further up the Arroyo Seco towards the bottom of Ken Burton Trail. For this ride, stay to the left and eventually you'll come to the base of an old debris dam with a steady waterfall flowing down.

When you're ready, turn around and head back out the way you came.

This trail gets good protection from the sun due to the steep canyon walls on both sides of the trail. Some trees also provide shade in the middle of the day.

History & Background

You'll see several cabin foundations that date back to the early 20th century.

Lots of stream crossings on the way up Gabrielino Trail.  It's a challenge not to fall in at least once!

Trails are in great shape, and clear of debris, the streams are low, water crossings were much easier that other times I've been here.
