Overview
Lost Lake is a 240-acre lake at 3,143 feet elevation on Mount Hood's north side, and the photograph taken from its south shore is one of the most reproduced landscape images in Oregon. Mount Hood's north face fills the horizon, and on calm mornings the entire mountain reflects in the still water with a precision that makes the image look composited. It isn't. This is just what Lost Lake looks like before the wind picks up.
The 3.1-mile loop around the lake is one of the flattest hikes in Mount Hood National Forest. With only 80 feet of elevation change, it's appropriate for families with small children, hikers with mobility limitations, older adults, and anyone who wants a beautiful walk without a significant physical challenge. It's the most accessible Hood hike suitable for visitors at any fitness level. The trail is wide, well-maintained, and shaded for most of its length by old-growth Douglas fir and western red cedar that have been growing here for centuries.
Lost Lake also has one of the best-equipped base camps in the region. The resort at the lake's north end operates a campground with reservable sites, RV hookups, rental rowboats and kayaks, a general store, and restrooms with flush toilets. It's a full-service destination, not a remote backcountry lake, which makes it excellent for families but means you should expect other people.
The Route
Starting at the Day-Use Area (0 to 0.5 miles)
The loop begins at the day-use area near the resort's main entrance, where the trailhead sign marks the start of the lake loop. You can walk the loop in either direction; counterclockwise (heading east along the north shore) is the conventional choice, saving the iconic south-shore view for the second half of the hike.
The first half mile follows the lake's north and east shores through old-growth forest. The trail is wide enough to walk two abreast and largely flat, with a few small root crossings and a plank bridge over a drainage at about 0.3 miles. Douglas firs here are enormous, some more than 200 years old with trunks five and six feet in diameter. Western red cedars with their distinctive stringy bark and buttressed bases fill in the lower canopy.
The lake is visible through the trees for most of this section. In early morning, before the day-use area fills with families, this stretch is quiet in a way that the busier south shore rarely is.
East Shore to South End (0.5 to 1.5 miles)
The trail rounds the east shore and approaches the lake's south end, where Lost Lake Creek drains out of the basin. This section has the most varied terrain on the loop: a small footbridge over the creek outlet, a short boardwalk section through a marshy area, and the best views of Mount Hood across the water.
The south shore, at about 1.2 miles, is where most photographers set up. Mount Hood's north face is centered above the lake here, with a clean sightline unobstructed by trees or resort buildings. If you want the reflection shot, arrive at the south shore before 9 AM on a calm morning. By 10 or 11 AM, thermals generate enough wind to break up the water's surface. Overcast mornings with low cloud can produce more dramatic light than bluebird days, particularly for photography.
West Shore Return (1.5 to 3.1 miles)
The west shore return is the longest and, arguably, most beautiful section of the loop. The old-growth forest is densest here, with fewer glimpses of the lake and more of the towering canopy. Sword fern, oxalis, and vanilla leaf carpet the forest floor. In late May and June, trillium blooms in the understory.
At about 2.3 miles, the trail passes the campground's walk-in tent sites, which border the lakeshore directly. These are among the more coveted campsites in the area, and they're worth booking well in advance if you're planning to camp at the lake. The loop returns to the day-use area and trailhead at 3.1 miles.
Permit Requirements
The Lost Lake Loop requires no wilderness permit and no Northwest Forest Pass. Instead, Lost Lake Resort charges a day-use fee of $9 per vehicle, collected at the resort entrance gate. This fee goes to Hood River County, which manages the resort under a special-use permit from the Forest Service. The distinction matters practically: your Northwest Forest Pass, America the Beautiful pass, or Interagency Annual Pass will not cover the day-use fee here. For a clear comparison of how national forests and national parks handle access fees and management, see national forest vs. national park.
The $9 fee covers parking and full access to the day-use area, including the beach, picnic tables, and restrooms. If you're camping at the resort, the camping fee covers the day-use fee as well.
When to Hike
May through October covers the full season for Lost Lake. The resort and access road typically open in early to mid-May, depending on snowpack at the lake's elevation. Unlike many Hood-area trails that sit above 4,000 or 5,000 feet, Lost Lake's 3,143-foot elevation means it opens earlier in spring and stays accessible later into fall.
The reflection is best in May and June, when snowmelt runoff keeps the lake full and the surrounding forest is most intensely green. Midsummer (July and August) is busiest: the campground fills on weekends, the beach gets crowded, and the day-use area can feel like a park on a holiday. Weekdays in July are a workable middle ground.
September and early October are the best months for an uncrowded visit. The campground empties out, the vine maple and bigleaf maple turn yellow and orange, and the mountain views take on the sharpness that comes with fall air. The resort typically closes for the season in late October.
The Huckleberry Mountain Extension
If 3.1 miles of flat trail isn't enough, a second trail leaves from the south end of the loop and climbs Huckleberry Mountain through unbroken old-growth forest. The Huckleberry Mountain Trail adds 3.5 miles round trip and about 1,200 feet of elevation gain.
The trail sees far less traffic than the lake loop and rewards patience with big timber and genuine quiet. The old-growth Douglas fir on the lower slopes of Huckleberry Mountain is some of the most impressive in the northern Hood area. The trail tops out near the mountain's 4,200-foot summit with partial views through the trees. It's a good option on a day when the lake loop feels too short or too busy.
For those who want to explore more of Hood after the easy loop, Elk Meadows on the northeast side offers a wildflower meadow with glacier views and similar north-side character. The Timberline Trail is the full circumnavigation of Hood and gives you the full-loop context for every individual hike like this one. The classic south-side complement to Lost Lake's reflection shot is Mirror Lake, which offers the same mountain-reflection photograph from a different angle and a 700-foot climb, about 45 miles south. If you're bringing kids or newer hikers to Hood for the first time, Tamanawas Falls on Highway 35 is another low-effort waterfall hike that works well paired with a Lost Lake morning.
What to Bring
For the 3.1-mile flat loop, the packing list is minimal. Carry water (there are water spigots at the resort, but treat the lake water if you're filtering from the source), a snack, and layers. The old-growth forest keeps the trail cool even on warm days, but the south-shore viewpoint and beach areas are fully exposed.
Camera gear is worth the extra weight. A tripod and a wide-angle lens give you the best chance at the reflection shot. Arrive at the south shore by 7 or 8 AM on a calm morning for the best conditions.
Dogs are allowed on the loop and on the beach, on leash. Clean up after your dog. The resort takes the condition of the area seriously, and the trail is heavily used enough that litter and waste have a cumulative impact.
Trailhead Access
Lost Lake is accessed via Hood River and the Dee Highway. From Hood River, take the Dee Highway (Oregon Route 281) south for about 10 miles to the town of Dee, then turn right onto Lost Lake Road and follow it for approximately 14 miles to the resort entrance. Total distance from Hood River is about 25 miles; the drive takes 35 to 40 minutes.
From Portland, the fastest route is US-26 East to Highway 35 North, then west on the Dee Highway. Total drive time from downtown Portland is about 1 hour and 45 minutes. The alternate route via Government Camp and Highway 35 adds roughly 15 minutes but is scenic.
The last 14 miles of Lost Lake Road are paved but narrow and winding, with sections of rough pavement and blind curves. Drive at reasonable speed and watch for cyclists and oncoming traffic. The road is not suitable for large RVs on the final approach; check with the resort before bringing a vehicle over 25 feet.
The resort general store is stocked with basic camping supplies, snacks, firewood, and beverages. The nearest full grocery store is in Hood River, 25 miles north.
