This touring bicycle loop is approximately 32.3 km (20 miles) long. With an average duration of about 2 hours and 15 minutes, it's a good half-day ride. However, your actual time may vary based on your fitness level and how often you stop to enjoy the scenery.
The loop primarily features hard-packed gravel roads and fire roads. While some sections might be paved, a significant portion is unpaved. Be aware that firelanes can be steep, muddy, and rutted, especially from November to June. Northwest Leif Erikson Drive, a key part of the route, is known for its gentle grade and hard-packed gravel surface.
This loop is rated as difficult for touring bicycles. It involves approximately 610 meters (2,000 feet) of elevation gain, with some fire lanes featuring steep gradients up to -17%. While sections like Northwest Leif Erikson Drive are more moderate, the overall route requires good fitness due to its length and climbs.
The loop can be enjoyed year-round, but conditions vary. Spring and fall offer pleasant temperatures and lush scenery. Be prepared for muddy and rutted sections on firelanes from November through June, making fenders a good idea. Summer provides drier conditions, but always check the weather forecast before you go.
