The Lost Lake and Interurban Trail Loop offers a compelling touring cycling experience, blending historical pathways with rugged natural terrain. You'll start on the gentle Interurban Trail, then tackle the more technical North Lost Lake Trail with its roots and rocks, before ascending the steep switchbacks of the Fragrance Lake Trail. Expect dense forests, the serene Lost Lake, and panoramic views of the San Juan Islands and Mount Baker from the Cyrus Gates Overlook.
This is a difficult 12.6-mile (20.3 km) ride with 1881 feet (573 metres) of elevation gain, taking approximately 2 hours and 17 minutes. It's not for beginners, requiring good fitness and technical skill, especially on the rugged sections. Plan your visit during dry weather to best enjoy the varied surfaces and challenging climbs.
Beyond the physical challenge, this loop is rich in natural beauty and historical intrigue, following a former electric railway line. The diverse terrain, from smooth paths to technical singletrack, provides a comprehensive adventure for touring cyclists, making it one of the more notable routes for those seeking a demanding ride near Whatcom County.
