A 19-mile tour of Tiger Mountain's most popular trails.

Eric Ashley


Welcome to Tiger Mountain, a popular multi-use recreation area that's seen an explosion of new trails and two-wheeled visitors. This loop details the mountain's most popular trails (as of 2017), but there's even more to see. There are some sections of road climbs, but the continued addition of singletrack means the riding only gets better year-to-year. Get ready for some long pedaling to access tons of exhilarating descents!

Need to Know

This loop begins with intermediate trails and progresses to extremely difficult, ending with the mountains most formidable and taxing trail Predator. Various modifications or bail-out points are possible and have been noted below.


1.) From the upper lot, start on the Tiger Mountain Connector. You'll quickly link to the Northwest Timber Trail on the other side of the road. If you parked in the lower lot, pedal up the road behind the yellow gate.

2.) Head up the Northwest Timber Trail to reach the start of Master Link on the left. This will take you for 2.5 miles of smooth and steady climbing that winds about through the trees. When you come to the road, cross over onto Quick Link for an additional .5 miles of singletrack that ends on Tiger Mountain Road 5500.

3.) Follow Tiger Mountain Road 5500 for .3 miles past the entrance of Predator until you come to a split. Take the right onto Tiger Mountain Road 5570. This is the steepest part of the road climb, but fortunately it isn't long. At roughly half-a-mile, the road crosses with the Summit Trail, the summit is just ahead.

4.) At the summit, take a breather and enjoy the views. Then charge into the Summit Trail for 1.5 miles of pumps, flow, and fun. After the initial road crossing, you could cut right to Off The Grid, but the rest of the Summit Trail is worth keeping to the left.

5.) The end of the Summit Trail feeds onto the Preston Railroad Trail, but for this ride, turn left and connect back to Tiger Mountain Road 5500 instead. Keep straight at the next two intersections (unless you'd prefer to go back up and ride all of Off The Grid). As mapped, climb to Drop In just across from Predator to cut in partway on Off The Grid.

6.) The remainder of Off The Grid serves up over a mile of aggressive flow that requires and rewards deft bike handling. There's some climbing, but most of the trail is downhill. Be aware of several dropping/lunging turns and a fair share of roots. The trail ends with a chunky exit onto Tiger Mountain Road 5500 near some picnic tables. This is a great place to regroup and rest for a bit.

7.) Once you're ready, continue onto Fully Rigid for a tight, twisty, and awkward passage that you'll either love or hate. Up next, continue onto Joy Ride for high embankments, vigorous undulation, tight turns, and recurring tech. All of these obstacles will confront riders to find the flow on this rough coaster ride that ends on the Northwest Timber Trail.

8.) Turn right for a casual pedal to reach the two-way Easy, Tiger. A little rolling terrain quickly leads to the top of The Legend. Climb south till you reach a natural clearing and drop-in. The Legend has similar pump-ability to the Summit Trail, but it features more tech and three rock-rolls, two of which are mandatory. It's a fast and fun trail that ends on a road across from Megafauna. If riders struggled here, skip Megafauna and turn left up the road to catch Easy, Tiger back up.

9.) Megafauna gets straight to the point with a steep and narrow roll-in. It backs off at a few points, but much of the trail is made up of steep, brake-dragging turns. Watch the signature rock roll/drop as you head down this pushy trail. At the bottom, Megafauna feeds onto Easy, Tiger for a smooth but steady climb out. At the top, turn left to follow the Northwest Timber Trail. It too is fairly casual, but there is one rootball-roll to watch out for.

10.) Back at Master Link, it's time to assess your party. If anyone was overly taxed so far or is feeling exhausted, they should continue out. Either follow the Tiger Mountain Connector or pedal up the road to ride the just the bottom of Predator, beneath the Dr. Rockso Roll. Otherwise, follow Master Link and Quick Link to the right and retrace your steps from earlier in the ride. At the top of the singletrack, take the road to the entrance of Predator on your left.

11.) Predator begins with a moderately steep climbing trail that tops off in a small clearing. From there, it's a raucous 1.8 miles with a bit of everything including steeps, roots, and berms. Plan on having a blast, but don't expect things to be easy. All of Predator is challenging, but probably the most formidable feature is the Dr. Rockso roll. This steep rock-roll exit onto the road was designed as a qualifying feature and to keep hikers off. Follow Predator across the road for the remaining thrills before it spits riders into the parking lot.

History & Background

Tiger Mountain is a multi-use recreation area near Seattle. In recent years, new trails and the continued work of Evergreen Mountain Bike Alliance and WA Department of Natural Resources have produced a surge in Tiger Mountain's popularity.
