Master Link and Predator Loop

This route offers a significant contrast in difficulty. The Master Link trail is rated 'Green' (easy) technically, but 'Moderate' physically due to its consistent uphill climb. The Predator Loop, however, is a 'Double Black Diamond' (expert) trail, demanding advanced skills, constant concentration, and excellent bike control due to its aggressive and technical nature.

The route starts and ends at the Tiger Mountain State Forest Trailhead in Issaquah, Washington. This is a common access point for the Tiger Mountain trail system.

Yes, a Discover Pass is required for vehicle access to trailheads and recreation lands managed by the Washington State Parks and Recreation Commission, Washington Department of Fish and Wildlife, and Washington Department of Natural Resources (which manages Tiger Mountain State Forest). You can purchase a day-use or annual pass.

The Master Link is a 2.4-mile singletrack with a surprisingly smooth and winding pedal through tall forests. The Predator Loop, on the other hand, is a diverse and challenging downhill experience featuring a mix of fast, flowy sections with berms, significant Pacific Northwest technical features like moderate steepness, small-to-medium drops, rollable doubles and tables, and descending rock gardens. It's particularly known for its roots and 'root gardens'.

The best time to ride is typically during the drier months, from late spring through early fall. While the lush forest scenery is beautiful year-round, the technical features of the Predator Loop, especially its root gardens, become significantly more difficult and potentially hazardous in wet conditions.

While dogs are generally allowed on trails within Tiger Mountain State Forest, specific rules may apply to mountain biking trails. Always check local signage and regulations, and ensure your dog is leashed and under control at all times. Be mindful of other trail users, especially on technical downhill sections.

The Predator Loop is renowned for its aggressive flow and technical challenges. Key features include a committing rock waterfall chute, a challenging rock roll feature, and extensive 'root gardens'. The upper section is particularly rooty and rocky, while the lower section, though still technical, is considered somewhat smoother. It also incorporates berms, drops, and tables.

Yes, this route utilizes several official trails within Tiger Mountain State Forest. The climb primarily uses the Master Link trail. To access the Predator Loop, you'll also connect with sections of the Quick Link trail and a portion of Crossover Road. The descent is primarily on the Predator trail itself.

While the trails themselves wind through lush forest, the general area of Tiger Mountain offers scenic views. From the summit, which riders access to begin the Predator Loop descent, you can often catch views of Mount Rainier on clear days.

Given the 'Double Black Diamond' rating of the Predator Loop, an all-mountain bike with approximately 150mm of travel is highly recommended. Experienced riders might also opt for a downhill bike to tackle the aggressive features and technical terrain more comfortably.

The Master Link trail is a dedicated uphill-only climbing route for mountain bikers, providing an enjoyable and efficient way to access the upper mountain trails like Predator. It's a much more engaging alternative to fire roads for your ascent, allowing you to save energy for the challenging downhill on Predator.
