Description

If you're looking for a genuinely pleasant touring cycling route that combines history with natural beauty, the Cross-Marin Trail Bridge – Marie Dhority Bridge loop from Lagunitas Creek is a fantastic choice. This moderate 12.2-mile (19.7 km) loop, with a gentle 820 feet (250 metres) of elevation gain, can be completed in about 1 hour and 29 minutes, making it perfect for a relaxed outing or family friendly cycling. It's one of those Lagunitas Creek cycling trails that offers high reward for relatively low effort.

What to expect on Cross-Marin Trail Bridge – Marie Dhority Bridge loop from Lagunitas Creek

The route largely follows the historic North Pacific Coast Railroad right-of-way, which means you'll enjoy a consistently mellow grade, making the 820 feet (250 metres) of elevation gain feel effortless. You'll cycle through varied woodlands, including groves of second-growth redwoods and oak-covered hillsides, all while paralleling the beautiful Lagunitas Creek. Keep an eye out for Coho Salmon and Steelhead Trout in the creek, especially during migration season. The trail surface varies, with paved sections in the north and gravel in the south, so a touring bike with wider tires will be most comfortable. You'll cross both the Cross Marin Trail Bridge and the Marie Dhority Bridge, each offering unique views over the creek and surrounding landscape.
