This is the Tiger Mountain trail network. It's been around for a couple decades, but has gotten some new attention within the last few years thanks to the Department of Natural Resources and Evergreen Mountain Bike Alliance.

If you're a local to the Seattle area, this is one of the better close rides. It offers nice views, some great flowy singletrack, and a significant amount of climbing.
You can shorten the ride by excluding the summit trail and riding directly to the Preston Railroad trail. However, I recommend including it for most pleasurable ride. Tiger Mountain goes in 5 parts:

1) The fire road climb up to the trailhead for the Summit Trail. Just crank up the dirt road - there's nothing special here, except a bunch of climbing.

2) Ride the Summit Trail until it connects to the Preston Railroad Trail. This trail is the newest addition to the network - it's fast, fun and technical. There are a couple of jump opportunities, but this is more for practicing turns, speed control and technical terrain.

3) Ride the Preston Railroad Trail to the eastern fire road. The Preston Railroad Trail is an XC trail at heart, that acquires some flow near the end. It's more difficult if ridden quickly and has numerous obstacles that are optional along the ride.

4) Ride the 2 miles south (start by turning left from leaving the Preston Railroad trailhead and right at the junction a 1/4 mile down the road) on the fire road until you get to the Northwest Timber Trail trailhead.

5) Complete the Northwest Timber Trail until it intersects with the fire road and turn left. The Northwest Timber Trail is a hiking trail first and a mountain biking trail second. Because of this, it's a bland trail that is a purebred XC offering. It provides some very pretty views and uniquely large number of bridge crossings, however the trail architecture itself offers nothing interesting and is more a glorified connector back to the main fire road so the rider may get back to the parking. Be respectful to hikers along this trail and watch your speed.

Ride the original fireroad you started on to get back down a 1/4 mile to the parking lot.
