Moran State Park has some of the most spectacular mountain biking trails in Western Washington. The 5000 acre park has several lakes, multiple campgrounds, and the highest peak in the San Juan Islands, the 2400 foot high Mount Constitution.

The best trails are open to mountain bikes from September 15 through May 15 each year. There are enough other low-elevation trails that stay open year-round to put together a decent mountain bike ride if you're visiting in the summer.

There is something for everyone with most of the longer trails being Intermediate.  Beginners will enjoy the easy trail out the east side of Mountain Lake among others.  Do not let the Grunt rating dissuade you, there are relatively flat trails, and if you can get ride to the top then many trails are mostly downhill.

Orcas Island tends to be much drier than most of Western Washington and makes one of the best winter riding areas in our region. Bring plenty of layers as the elevation and marine environment can make for chilly temperatures, even on warmer days.

Eastsound is the largest town on Orcas Island with full amenities and services, and is only a few minutes a way. There are plenty of places to stay, including high-end resorts such as Rosario, and plenty of smaller hotels and vacation rentals.
