Description
The run starts at Chantry Flats and follows the Gabrielino trail through the Angeles National Forest, where it emerges in Altadena near the Jet Propulsion Laboratory. We’ll keep going from there south past the Rose Bowl to Brookside Park for a celebratory picnic.
Notes:
- You can take either the upper or lower trail at the split before Sturtevant Falls.
- The condition of the trail after Newcomb Pass is uncertain. We are trying to get more information and will update this site based on what we find.
- The distance and elevation are from Strava, which tends to be somewhat inaccurate. We won’t have better information until we complete the run.
