Sunset Ridge is one of the most fun and challenging single tracks in the front side of Angeles National Forest. It's normally ridden downhill but definitely use a bell and be aware of hikers & trail runners, especially on busy weekends. There are many rock drops, tight switchbacks, and plenty of extreme exposure. A seriously fun trail with equally serious consequences. Definitely take it easy your first time. Sunset Ridge is a fantastic trail with great views and many challenges.

Access Info

You can access Sunset via Chaney Trail and climbing up the paved fire road. It's a steep climb up the paved road and Sunset starts from the left of the road almost 2.5 miles from the locked gate.

You can also get to Sunset by climbing up the Lower Sam Merrill trail at the top of Lake Ave. This trail is heavily switchbacked and very, very popular with hikers. If you go this route, you hang a left at the top on the connector trail and climb up to the paved fire road. From there descend maybe 50 yards and Sunset Ridge will be on your right hand side.

       First time today on this amazing trail. Extreme exposure, especially the tight 180 degree turns. Well groomed and moist from recent rain. Highly recommended for the expert rider.

       Super fun and fast. Some nice technical parts too. With a little rain dirt gets awesome.

       Technical and rocky. I think this trail is fun, but it only gets Five Stars because its in SoCal!

       Best trail on the front side of the mountain. Technical rock gardens mixed with fast exposed single track make for a thrilling 6-12min descent depending on skill.

       First time I’ve written this trail. Very technical at the top but manageable. Dry conditions with lots of overgrown poison oak. Wear protective clothing if you are susceptible to poison oak rash.
