The Mount Hood loop is the best day ride you can do from Portland without leaving for the weekend. The Federal Highway Administration designates it the Mt. Hood Scenic Byway, a 105-mile (169 km) National Scenic Byway with no fees, running out along the Historic Columbia River Highway and I-84 to Hood River, south on OR 35 past the mountain's east flank, then west on US 26 through Government Camp and back to Portland. Allow three hours to ride it without stopping and eight to actually use the day. Unlike the Cascade passes to the north, it stays open year-round.
What the loop gives you
Three completely different landscapes in one tank of fuel. The northern leg is river gorge — basalt walls, waterfalls, the Columbia running wide below you. The eastern leg on OR 35 is orchard country climbing into fir forest, with the Hood River valley full of pear and apple blocks and the mountain appearing and disappearing between ridges. The southern leg on US 26 is high Cascade forest at Government Camp, where the road tops out and the ski areas sit.
The limitation to be straight about: this is a scenic touring loop, not a corner-carving road. US 26 is a busy four-lane arterial for much of its length with heavy weekend ski and recreation traffic, and OR 35 is a fast sweeper road rather than a technical one. If you want tight switchbacks, take the Rowena Loops detour on the eastern Historic Columbia River Highway and treat the rest as a scenic connector.

How the byway is actually put together
It is worth understanding that this is a stitched route rather than one continuous purpose-built road, because that explains the uneven character. The FHWA byway listing puts the length at 105 miles with no fees and three hours of driving time. The designated route starts at the western end of the Historic Columbia River Highway near Troutdale, uses I-84 along the river to Hood River, picks up OR 35 south, joins US 26 near Government Camp and runs west back toward Portland through Sandy.
That means one leg is a 1910s scenic highway, one is interstate, one is a rural state route and one is a busy mountain arterial. Riders expecting a single consistent road are disappointed by the I-84 section in particular. The fix is simple: run the Historic Columbia River Highway instead of I-84 where it is open, and accept a slower, better morning.
Which direction to ride it
Counter-clockwise, out along the Gorge first and back over the mountain, is the version most riders recommend. It puts the Historic Columbia River Highway and Hood River in the cool part of the morning, gets you past the Multnomah Falls congestion before the crowds build, and leaves the Government Camp descent for late afternoon when the light on the mountain is at its best. It also means the eastern OR 35 climb happens while your tires are properly warm.
Clockwise has one real argument: if you are starting late, US 26 out of Portland moves faster than the Gorge and gets you to the mountain sooner. It also puts the waterfall corridor at the end of the day when the timed-permit window at the Multnomah Falls lot has closed.
OR 35 and the Hood River valley
Turning south from Hood River, OR 35 runs up the valley through orchard blocks with the mountain standing directly ahead. This is the quietest leg of the loop and the one that most feels like a ride rather than a drive. The road climbs steadily, the orchards give way to fir, and there are marked viewpoints where the whole east face opens up.
The junction with US 26 near Government Camp is the top of the loop. From there a short spur climbs to Timberline Lodge at 6,000 feet — a hand-built 1937 WPA project dedicated by Franklin Roosevelt, declared a National Historic Landmark in 1977, and still the highest point you can ride to on the mountain. The road up is steep, tight and worth doing; the lodge itself draws close to two million visitors a year, so the lot is rarely empty. Note that an Oregon Sno-Park permit is required there from November 1 through April 30.
The Barlow Road and the historical layer
The southern leg follows the last leg of the Oregon Trail. Rather than raft the Columbia, emigrants from 1846 onward took the Barlow Road around Mount Hood's south side — including the descent at Laurel Hill, where wagons were lowered on ropes. The Forest Service keeps interpretive sites along the byway, and the FHWA's own description of the route leans on this history. It is a genuinely different reason to stop than another viewpoint, and the pullouts are usually empty.
Season, traffic and fuel
The loop is open year-round, which does not mean it is always rideable. The mountain sections get snow, and Oregon posts snow zone signs with traction tire or chain requirements when conditions warrant. The Forest Service's own byway page points riders to TripCheck for closures, delays and traction requirements, and that is the right morning-of check from roughly November through April. A posted snow zone on US 26 is a reason to turn around, not a challenge.
Weekend traffic is the summer version of the same problem. US 26 between Portland and Government Camp carries the region's entire recreation load on Saturday mornings and again Sunday afternoons, and it backs up. Riding the loop counter-clockwise and getting over the mountain before mid-afternoon avoids most of it.
Fuel is easy on this route. Troutdale, Hood River, Government Camp and Sandy all have stations, and no leg is long enough to be a problem on a normal tank. The Gorge legs have the most options; OR 35 has the fewest, so top up in Hood River if you are unsure.
Deer and elk. The forested sections of OR 35 and US 26 have regular wildlife crossings at dawn and dusk, and the sightlines through dense fir are short. Ride the early morning and late evening legs accordingly.
Gear notes for this loop
Cell coverage drops out on the mountain sections and in parts of the Gorge, so a route that depends on live data will stall exactly where the junctions matter. Loading the loop offline onto a bar-mounted riding system solves that, and our route planning guide covers building it with the Timberline spur and Rowena detour as optional branches rather than a single fixed line. A JADO S6 riding system runs navigation and cameras together, which is useful on the US 26 stretch where you are sharing four lanes with distracted weekend traffic.
The elevation range is the other planning input. You start near sea level at Troutdale and top out around 4,000 feet on US 26, with the Timberline spur adding another 2,000. That is enough temperature change to move tire pressure measurably, as our tire pressure guide explains, and enough of a temperature drop that riders who dressed for a warm Portland morning regret it by Government Camp. A TPMS sensor set covers the first problem; layering covers the second.
FAQ
How long is the Mount Hood loop?
105 miles (169 km) as the FHWA designates the Mt. Hood Scenic Byway. Three hours of riding without stopping, or about eight hours to do it properly with viewpoints, Timberline and lunch in Hood River.
Is the loop open in winter?
The roads stay open year-round, unlike the Cascade pass routes further north. Snow zone traction requirements are posted on the mountain sections in winter, and conditions on US 26 and OR 35 can turn quickly. Check TripCheck the morning you ride.
Which way round is better?
Counter-clockwise — Gorge first, mountain second. It beats the Multnomah Falls crowds, warms your tires before the OR 35 climb, and puts afternoon light on the mountain.
Can you ride to Timberline Lodge?
Yes. A paved spur climbs from US 26 near Government Camp to the lodge at 6,000 feet. An Oregon Sno-Park permit is required there from November 1 through April 30.
Does it combine with other rides?
Directly. The western end shares the Historic Columbia River Highway with the Columbia River Gorge route, so many riders run the two as one long day or split them across a weekend based out of Hood River.
