Trail Name: This trail loop primarily uses Leif Erikson Drive which is open year round. It is located within Forest Park, and utilizes a singletrack favorite (fire lane #1).
Location: Click the green mountain biker on the map below for driving directions to the trail head.
Parking: Perking is free. There is limited space but you can also find parking along NW Thurman (watch for the no parking signs…they’ll tow you). Outhouses and drinking fountains are available.
Riding level: This entire 15 mile loop is not for beginners and will accommodate both intermediate and advanced riders. Leif Erikson is perfect for beginners because it is nice and wide while exposing you to some beautiful terrain. This ride can easily be made into an out-and-back (the way back on Leif Erikson will be mostly downhill).
Trail Type: Most of the loop is on a dirt road, there is about a mile of singletrack, and about two miles of paved road.
General topography: You can expect to climb 600 feet but it is done over several miles so the climb is not as strenuous as it might sound.


Description: Nearly 100 years ago, city planners had the wisdom to secure this hiker/biker playground that we can enjoy today. Expect to see fantastic views of fern covered cliff sides, forested terrain with that signature northwest moss, and an abundance of wildlife.
With Powell Butte and MT. Tabor in South East Portland, and Forest Park in the North West part of the city, there is plenty of beautiful mountain biking trails to ride without ever having to travel far from home. There is much more to Forest Park than the Leif Erikson loop described here, but this is one way I like to attack this trail system.
The majority of this ride takes place on the wide dirt road we call Leif Erikson. You’ll begin your return trip when you take a left on NW Skyline Boulevard. Mountain biking purists will be unhappy with this route since this portion is on pavement. But don’t you worry one second about that, because you’ll be rewarded with a sweet singletrack descent on Fire Lane #1. This will spit you out on Leif Erikson again, and you’ll be able to coast on back to your car from there.
Leif Erikson is a great workout for beginners and experts alike because the climb is gradual. Instead of the trail dictating your speed, you get to decide how fast to go and how hard to push yourself. On weekends, this trail can be crowded so watch for pedestrians, but it is a very wide trail so there is always plenty of room.
