This moderate 9.2-mile (14.8 km) route packs in 1625 feet (495 metres) of climbing, taking roughly 1 hour and 33 minutes to complete, making it a challenging yet incredibly rewarding ride for those seeking diverse terrain and panoramic vistas.

What to expect on Mount Constitution – Mountain Lake Loop Trail loop from Moran State Park

The journey on this route is a constant evolution of scenery and terrain. You'll start by winding through dense, mossy old-growth forests, feeling immersed in the ancient woodlands of Orcas Island. As you ascend towards the 2,400-foot Mount Constitution, the trees gradually give way to more exposed areas, revealing increasingly spectacular panoramic views of the San Juan Islands, the Salish Sea, and even Mount Baker on a clear day. The final push to the summit is a significant climb, but the reward is the iconic stone observation tower and a 360-degree vista considered among the best maritime views in the world. The Mountain Lake Loop portion offers glimpses of the lake itself, with Mount Constitution rising majestically beyond its northern shore, providing a varied and engaging experience for riders comfortable with strenuous sections and significant elevation changes.

Planning your visit

Planning your mountain biking trip to Moran State Park requires careful attention to seasonal access. Most mountain biking trails, including singletrack sections of this loop, are only open from September 15th through May 15th each year, so make sure your visit falls within these dates. The trails are multi-use, meaning you'll likely encounter hikers and possibly equestrians, so proper etiquette, including yielding, is essential. This route is a fantastic way to experience the park's diverse terrain and elevation, but be prepared for a challenging ride.
