Some of the trails on this loop are only open to bikes from September 15th to May 15th, so make sure to plan accordingly. The State Park is much quieter during the off season and the trails are very empty so a bike is a great way to really explore the park. This loop will take you up to a high point and then down into some great lake basins in very lush forest.

Need to Know

Some of the trails on the route are open to bike only from September 15th to May 15th. You'll need to take a ferry to get to the island. Be aware it can be expensive to take the ferry with a car, so if you can ride onto the ferry with your bike and then use the island bus service to get to the State Park you'll save a considerable amount of money. Be aware that the island bus runs only in the summer tourist season and has historically been a bit spotty. Their schedules and rates are published here.

For more information, call the park at: 360-376-2326.


This is a big epic loop in Moran State Park on one of the most scenic islands in the San Juans.

Once in the State Park, the ride begins with a climb up the main park road on pavement. When you are almost to the summit, you'll peel off onto Little Summit Trail and finish the climb to the summit on singletrack.

From the summit, you'll descend to the North Trail which will take you around the outside of the park on a very lush and fun trail. The descent on the North Trail is one of the highlights of the loop. At the end of the North Trail hang a left on the Mt. Constitution Trail to soon connect with the Twin Lakes Trail. The Twin Lakes Trail is a little more heavily used and is not the nice, narrow singletrack found on the North Trail.

Take in the Twin Lakes before descending to Mountain Lake. Follow Mountain Lake Trail East around the lake, and then make sure to keep left onto the Cascade Creek Trail since the other option is hiking only. The Cascade Creek Trail is a fun descent back towards the start.

This loop can be made bigger or smaller depending on ability. Just be aware of the trail restrictions. If you plan to make any changes to the ride, please study the map and/or call the State Park.

Great loop! Mountain lake loop has some closures. This route starts/finishes in south campground, not from a parking lot. A bit confusing at first. 13.3mi — 1h 40m
