“An easy outing on the Gabrielino Trail from Red Box picnic area to Valley Forge Campground”— Tim Whalen
Off to the right of the trail you'll spot some big buildings. This is the site of the Long Beach School District's Hi-Hill Outdoor School. It has been closed since 2008 due to fire danger and cost savings but was spared by the Station Fire in 2009. You'll pass several old cabins soon after but another marker below them marks the continuation of the Gabrielino Trail (NRT). The trail cuts through a big patch of blackberry bushes. Take a few to power you through the next section of trail if the season is right.
About 1.5 miles past the road you'll see a sign to Valley Forge campground and leave the Gabrielino Trail (NRT) to the left. Continue along a short downhill stretch and you'll arrive at the campground. There are several picnic tables, some signboards and vault toilets at the campground. The journey back out to the Red Box trailhead will take a little longer as you climb back up the arroyo.
A popular variation that uses a short car shuttle is to take the Valley Forge Trail #12W09 down from the Mt. Wilson Red Box Road and return back to Red Box on the Gabrielino Trail (NRT).
