2 New Trails Open on East Tiger Mt: "Easy, Tiger" and "The Legend" form a lollipop loop off of the Northwest Timber trail. Easy Tiger is a green level 2-way trail that will primarily be used as the return path for The Legend, the more difficult descent. Construction of extensions to both trails will continue this fall, so stay tuned for work parties. Eventually Easy Tiger will connect all the way to the Raging River State Forest!
With many miles of mountain biking trails spanning a wide variety of skill levels and physical challenge - including a bona fide double-diamond DH trail and killer views of Mount Rainier from the summit - Tiger Mountain is one of Seattle's most popular mountain biking destinations.
All trails are open year round, but during the winter months or after significant weather events, the trails are subject to closures: check for updates on this page and on the DNR's Tiger Mountain page here.
There are also many miles of logging roads that are open all year long, but these too may be closed (typically for timber harvest). Check the DNR link above.
Tiger mountain can get slick and stay that way for a bit following rain. Significant trail rerouting and maintenance efforts over the years have drastically improved Tiger's recovery and rideability due to rain, but due to the traffic it receives, it's still wise to avoid in rainy weather.
Tiger's summit is high enough to receive significant snowfall during winter months, and there may be intermittent closures of the upper trails during snow events.
Most of the trails are smooth and flowing, with intermittent gnar. Exceptions include Predator - which features very steep and very garnly technical sections, optional airs, root gardens, and a puckering rock chute; and Fully Rigid - which is a tight and twisty, rooty technical challenge.
Iverson and NW Timber see significant use by hikers. Watch your speed here!
Evergreen is underway with a major improvement of the Tiger Mountain bicycle trail system.
From Seattle take I-90 East to Highway 18. Continue South on Highway 18 for 4.4 miles, until you reach East Tiger Summit on your right. There are two main parking areas, both accessed from the highway 18 summit. The upper area is gated and is locked at 8:00 PM per the sign on the gate. This area also includes pit toilets. The road to the upper area travels travels west just above the lower parking lot.
A Discover Pass will be required to park at the upper lot. See here for details on obtaining a Discover Pass.
If you have a smart phone, there are dozens of apps available to help you find great routes through Tiger's awesome and growing trail system. Here are just a few:
- Download the Avenza PDF Maps app (http://www.avenza.com/pdf-maps) and the Tiger Mt Bike Trails GeoPDF Map above.
- Download the Maprika app (http://www.maprika.com/) and their Tiger Mountain map (http://www.maprika.com/maplink.php?id=8343).
- Download any GPS app and the GPS file above.
A common route for a couple hours at Tiger is:
- From the upper parking lot, ride up the connector trail to the road intersection.
- Find the bottom of NW Timber across the road, and ride up NW Timber until the intersection with Master Link on the left.
- Take Master Link all the way up to its road intersection.
- Find the bottom of Quick Link immediately across the road, and ride up Quick Link to its road intersection.
- Turn right on the road, and ride up the road.
- If you're going for the summit, keep riding on the road and follow the signs to the summit. If you're gunning for Predator instead, find its ride-up on the left before the first road intersection.
- From the summit, enjoy the view and take a breather. Then flip your travel and dropper post switches, and take the East Tiger Summit trail!
- Cross the road and continue on East Tiger Summit.
- At the first singletrack intersection, you can stay left for the full East Tiger Summit trail to Preston, or go right for Off The Grid. Assuming you take Off The Grid, you'll eventually come to a road intersection.
- From this intersection, descend the Fully Rigid trail. At the bridge intersection, you can either go left for Silent Swamp (and loop back up to the top of Fully Rigid via the road), or right for Joy Ride.
- Assuming you take Joy Ride, continue onto NW Timber at the bottom of Joy Ride, and then back to the parking lot.
Some general trail descriptions below:
- Master Link is a one-way climbing trail from the parking lot to roughly 3/4 of the way up the mountain. It's a climbing masterpiece - smooth and lots of friendly grade reversals to get you up top quickly and with gas in the tank.
- Quick Link is also a one-way climbing trail that picks up where Master Link leaves off, getting you a little bit further up the moutain - just enough to session Predator. If you're going all the way to the summit, you'll need to get the rest of the way from here by road.
- Predator is a true DH (yes, downhill!) trail rated double-diamond/experts-only. It features 1.8 miles of steeper and more challenging terrain, including a committing rock waterfall chute. This one-way descent is full of rock-armored steeps, with some tight turns over fast and undulating terrain packed with obstacles that will keep even highly skilled riders challenged. This trail crosses the main Tiger road near the bottom (where it becomes "Lower Predator", which can be ridden as a short standalone trail from the bottom), and terminates near the end of Iverson.
- East Tiger Summit is extremely fast and flowly, requiring minimum pedaling, and overall pretty buff but with a few gnarly spots. Bit of a physical grunt to get to the top, but a Blue Square descent.
- Off the Grid is 2.5 mile mostly downhill trail that peels off to the right just after you cross the road when descending the East Tiger Summit trail. It rides like a good mix of Joy Ride and Fully Rigid, but does contain a few short climbing section. It exits directly above the entrance to Fully Rigid. Classified as a Black Diamond.
- Fully Rigid is a short, technical trail that connects the road above NW Timber to the intersection of Silent Swamp and Joy Ride. It has some very tight and gnarly sections, and is intended to be ridden in the downhill direction, and is an extreme challenge to climb! Black Diamond downhill, Double Diamond uphill.
- Silent Swamp is a rolling elevation trail that connects the bottom of Preston to the top of NW Timber (via Joy Ride) without needing to ride the road. It's also a great way to get some more mileage in by combining it with the return road climb as a loop from the bottom of Fully Rigid back to the top of Fully Rigid. Pretty much a Green Circle trail, and not ridden much (great if you're looking for a little solitude).
- Joy Ride is similar to the East Tiger Summit Trail - flowy and fast with some rollers in places. Blue Square.
- NW Timber is a mostly buff Green Circle that can be ridden either direction, but has a few intimidating cruxes that a fair number of riders might dismount for (the infamous off-camber root drop near the ledge). This trail is nearest to the trailhead; watch for hikers and riders going both ways.
- Iverson is considered moderately technical, and is a bit of a grunt in either direction. Call it a Blue Square. This trail is probably the least ridden on Tiger - definitely worth checking out if you're looking for some alone time on the bike.
- Preston Railroad Grade is also fast but more technical than the Summit Trail, with roots, rocks, some gnar sections and some switchbacks. It requires very little pedaling in the downhill direction, but can be ridden either way. It's a challenge in the climbing direction! Blue Square.
- Preston Bailout Radness (PBR) is a relatively short, .4 mile, trail off of the third switch back on Preston that offers an alternate way to the crossover road that removes most of the climb to Fully Rigid. It’s a rooty, technical flow trail that crosses the characteristics of Fully Rigid and Joy Ride with excellent sight lines and several bermed turns. Blue square/black diamond descending, black diamond climbing. Note this trail is designated as descending riders having right-of-way.
- Only Puget Power Trail and High School Trail are open to mountain bikes.
- Bus Trail and Bonneville Trail are both not signed for limited use (Use your best judgment).
- All other trails are off limits to bikes
- From the bottom of the High School Trail, take your first right, then left at the 'T' up to Puget Power
- The climb up from the High School to Puget Power is 18%-20%, High School is about 15%
- High school is smooth double track, Puget Power is a middle chain ring fire access road.
- It's 2.8 miles from the High School to the High Point Trailhead. Out and back using Bonneville is about 7.5 miles
- Grunt 3 | Tech 1

The excitement on Tiger continues with greater trail diversity off the Northwest Timber trail, more low-elevation options, and a future route to the expansive trail system currently in construction at the Raging River Project.
In Phase III, mountain bikers can look forward to two new trail additions coming off Northwest Timber:
Trail 1: More Descent
Modeling the exciting technical descent of Predator, the first trail will be a toned-down but still stoke-inducing ride of 1-mile down mountain from the NWT.
Trail 2: Climbing & Two-Way
After enjoying the descent on the new trail #1, riders can rejoin NWT via the (2-way) trail back. Eventually, this trail will actually serve as the connector to the Raging River Project.
Both new trails are scheduled for completion by December 2017. But with the continued help of our dedicated volunteers, we’re hoping that can be much sooner.
