Central Cascades Day-Use Permit (Marion Lake)

Marion Lake: what makes it different

Marion Lake is the westside Mount Jefferson trailhead, a short drive up a gravel road from Highway 22 at Marion Forks. It leads to Lake Ann, Marion Falls and the largest lake in the wilderness, and it sells 44 day-use people and 7 overnight groups a day.^1,2,4

Getting to the start

The Willamette National Forest directs you east from Detroit on Highway 22 for 16 miles to Marion Forks, then left onto Marion Creek Road (Forest Road 2255) for 5.5 miles to the trailhead at the end of the road. Oregon Hikers counts 4.5 miles on that road from the highway, and a 2009 Oregon Hikers post says five. Plan on about five.^2,4,5

Parking is a fee site: $5 per vehicle per day or a recreation pass, paid through the Recreation.gov app because the page says no cash or checks are taken on site. There is no drinking water. Picnic tables are listed, and Hiking Project says the lot holds about 15 vehicles. Marion Creek Road is gravel and usually fine for a passenger car in summer.^2,8

Two older guides give the trailhead elevation as 3,360 feet and Marion Lake as 4,130 feet.^7,5

The first leg

The first half mile runs through a logged area with young trees and thick understory, then the trail enters the Mount Jefferson Wilderness under older forest. The Forest Service describes the lower trail as Douglas-fir, western hemlock, western red cedar and Pacific yew.^7,3

Lake Ann comes first, about 1.2 miles in by Oregon Hikers. You hear its outlet under the rocks but do not see it. At the next junction with Marion Outlet Trail #3495 you can walk the lake loop either way, and both sides meet at a bridge over Marion Creek.^4,7,3

Terrain and difficulty

Oregon Hikers rates the lake hike moderate at 6.2 miles round trip with 975 feet of gain. The grade to the lake is steady and gentle apart from about a mile of steeper climbing to Lake Ann. Hiking Project measures a longer version with Marion Mountain and the falls at 11.3 miles and 2,712 feet.^4,7,8

The Forest Service says the trail crosses a talus slope and a rock-covered slope near the lake, and ends at the junction with Minto Pass Trail #3437 and Lake of the Woods Trail #3493. Hiking Project places parts of the route in the 2015 fire and the 2002 Mount Marion Fire.^3,8

Quota at this entry point

• 2026 daily quota at Marion Lake, day use: 44 people a day. The Forest Service splits it 18 permits at the 10-day release and 26 at the 2-day release.¹
• 2026 daily quota at Marion Lake, overnight: 7 groups a day. Three groups a day come from the full-season release and four from the 7-day release.¹

Rules specific to this entry point

Central Cascades permits are required here from June 15 to October 15 for day and overnight use. The Forest Service trail page prohibits campfires at Marion Lake and at Lake Ann and requires weed-free feed for stock.^2,3

Camping at the lake is limited. Hiking Project says the shore between the peninsula on Blue Lake Trail #3422 and the Marion Creek bridge is day use only. A 2025 Oregon Hikers report also calls camping at Marion Lake limited.^8,6

Where it leads

Marion Lake is called the largest lake in the Mount Jefferson Wilderness. Marion Falls drops about 60 feet from a spur on the Outlet Trail, with a steep scramble to its base and a more exposed route on to the lower tier, Gatch Falls. A footbridge half a mile past the falls meets Blue Lake Trail #3422, and a user path down a scree slope reaches the shore for a view of Mount Jefferson.⁴

From the same junction the Minto Pass and Lake of the Woods trails go deeper into the wilderness. A 2009 post lists routes to the Eight Lakes Basin and the Pacific Crest Trail, and a 2.5-mile trail up Marion Mountain.^3,5

What trip reports say

A June 2009 Oregon Hikers post from pdxgene found four or five other people at the lake despite its heavy-use label, brook trout jumping, anglers in inflatable boats, ospreys, and Three Fingered Jack standing over the water. Circling the lake with photo stops took about two hours. A volunteer fish-stocking event had drawn a crowd at the trailhead that week.⁵

A July 2025 six-day loop started and ended at this trailhead. The writer got a permit for two a few days ahead after snow changed the first route, stopped at the lake on the last morning, and met a Forest Service worker near Lake Ann headed in to maintain a trail who said much of the Lake of the Woods Trail had been cleared the year before.⁶

A Hiking Project check-in from July 2023 logged the lake loop with the waterfalls at 6.5 miles in 3 hours 50 minutes.⁸

When to go from here

Oregon Hikers gives June through November for the hike, while the permit season is June 15 to October 15. The road is not maintained for snow and ice, so call the Detroit Ranger Station before an early or late trip.^4,2

Compare with nearby entry points

• Pamelia Lake: Pamelia Lake is the other westside Mount Jefferson trailhead off Highway 22. It sells 28 day-use people a day against 44 here, and 7 overnight groups, the same as Marion.¹
• Jack Lake (Canyon Creek Meadows): Jack Lake, on the east side, sells 72 day-use people but only 3 overnight groups. Marion Lake has the larger overnight quota of the two.¹
• Duffy Lake: Duffy Lake sells 34 day-use people and 7 overnight groups, so its overnight room matches Marion Lake while its day quota is lower.¹
