Fire Lane 10
The far north's one fire lane you can actually get onto — a rideable spine to old-growth giants and a hidden pond.

The Walk
Start at the Newton Road Trailhead, up on the Skyline side, where the lot has two park gates: the north one is Newton Road, the south one is Fire Lane 10. Take the south gate and point downhill. The lane falls about 475 feet over its mile-and-a-bit to the creek — a steady, moderate grade for most of the way, with one genuinely steep pitch partway down. If your knees or your brakes would rather skip that pitch, the Keyser Trail spurs off and rejoins below it, bypassing the worst of the drop; both ends land back on Fire Lane 10.
The old-growth arrives early. On the upper stretch you pass a stand of Douglas-fir with the deep, fluted, barrel-wide trunks that only come with a couple of centuries of growing — the largest collection of these giants between the top gate and the creek. In a park that is mostly second-growth forest with ambition, this is the real thing, and it’s easy to walk past at a connector’s pace.
Forest Skill: read an old-growth Douglas-fir Look for three things. The trunk: a true veteran flares out at the base like a barrel, wide enough that two people can’t ring it. The bark: deeply furrowed and thick — corky ridges you could lose a fist in, the tree’s own fireproofing. And the height: your neck gives out before the canopy does. These aren’t the pole-straight young firs of the regrowth; they’re what the forest looked like before the saws, left standing here by luck and by later protection.
Partway down, the lane crosses the Wildwood Trail just short of its Milepost 25½ — worth knowing if you’re on a bike or a horse, because the Wildwood is foot-only, so that’s a crossing, not a turn. Near the upper Keyser junction the forest opens onto its second surprise: a small, still wetland pond, the kind of quiet water that collects birdsong and light and not much foot traffic. Below the steep pitch the lane dips through a creek and climbs back out, and lower still the Linnton Trail comes up to meet it — the walking route from Highway 30 — before Fire Lane 10 carries on toward Newton Road and the rest of the network.
Cyclist & runner note This is one of the handful of fire lanes where riding is legal, and the best rideable line in the far north — but it’s a shared natural-surface road, so control your speed on that one steep pitch and yield to whoever’s climbing. It links cleanly into the Linnton-area loops (down the Linnton Trail, back up via Newton Road and the Wildwood), which is the real reason to know it. Runners get a steady moderate grind with a genuine forest payoff instead of a gate in the weeds. Just remember the Wildwood crossing is foot-only where it cuts your route.
Forest Park is stitched with numbered fire lanes — firebreaks and access roads that double as the park’s runnable, rideable network; Fire Lane 1 is the one to read if you want the whole story. Fire Lane 10 is the far north’s most useful member of the set, and that usefulness is the point.
Before you go
Two truths shape a trip here. First, mud: the upper half stays firm well into the wet season, but the lower stretch toward the creek softens and slops from October into spring — the kind of grade that chews up under a spinning wheel when it’s saturated, so save the full descent for drier weather or turn around at the pond. Second, there’s no parking at the very bottom, so this is a route you either climb back out of or fold into a loop — the Linnton Loop through Linnton and the Clark & Wilson parks is the classic, and Fire Lane 10 anchors several longer far-north circuits besides.
Come self-sufficient: no water, no restroom at any of the gates. And park smart — the far-north trailheads are known for vehicle break-ins, so leave nothing worth taking in view.
Then, if you’ve got the time, stop at the pond near the top of the Keyser junction. Most people out here are passing through to somewhere else. Stand still a minute. It’s the reward the map doesn’t mark.
Getting there
One way · from Newton Road Trailhead
- Start
- Newton Road Trailhead, top of NW Newton Rd off NW Skyline Blvd (~5 mi past Cornell), Portland
- Orientation
- Far-north/Linnton corner of the park, up on the Skyline side; turn down NW Newton Rd 0.3 mi to the lot — the south gate is Fire Lane 10; ~25 min from downtown
- Parking
- Real free lot at the Newton Road Trailhead — 'plenty of parking,' rarely full this far out; the Germantown Rd / Wildwood pullouts are another option. Both are known for car break-ins, so leave nothing in view
- Other access
- From the Germantown Rd / Wildwood trailhead, walk the Wildwood Trail north about three-quarters of a mile to where it crosses Fire Lane 10 (that stretch is foot-only)
- On foot from Linnton (Hwy 30) up the Linnton Trail, which climbs to join Fire Lane 10 a bit over half a mile up
- Ends at
- Drops past the Wildwood crossing toward the Linnton Trail and Highway 30; there's no parking at the very bottom, so most people loop back via Keyser and the Wildwood, or return the way they came
- Transit
- Bus 16 runs Hwy 30 through Linnton — the rare far-north access a bus can reach; from the stop, climb the Linnton Trail to meet Fire Lane 10 (a real climb, not a stroll)
- Accessibility
- Not accessible — a natural-surface dirt-and-gravel fire-lane road with one steep pitch and no facilities at any of its gates
- Dogs
- leashed
- Best
- year-round, and a rare far-north route that's genuinely rideable — keep it a daylight outing; the lower half muddies Oct-spring
