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.

Great dirt, trail encroached by tons of sharp weeds and poodle dog, came away with rashes. Wear pants! Rode on 4/15 and reporting very late.

      Rode this today, very fun trail, A little overground, your shins and Elbows will brush up against tall grass weeds

      Dusty and a bit loose. Feels a bit more skinny in places. Watch the exposed sections.

      We hope you've been enjoying Trailforks!
