North of Crater Lake, the North Crater Trail can be combined with Summit Rock to Crater Tr1457 as a loop ride from the north Diamond Lake Howlock Mountain TH.
The 2020 Thielsen fire affected the Mount Thielsen Wilderness trails. See the Umpqua NF Site for closure maps.
As always, it is best to call the local Ranger District for trail conditions and other restrictions prior to visiting, as the UNF website may not contain trip-specific details.

These trails cross open meadows over rolling terrain and are also popular with Nordic skiers. The North Crater TH provides access to Pacific Crest Trail 2000-D.
Summit Rock to Crater Tr1457 is an abandoned Summit Rock road bed. As with any easy-access trail, expect interaction with campground hikers while alongside the lake. The Diamond Lake CG has 238 campsites, and is very busy during peak season.
Equestrians: All of the area trails are open to riding. A summertime horse rental concession is adjacent to the Howlock Mountain Tr1448 TH.
Mosquitoes are ferocious in this area until August. Feel free to try the natural repellents, and avoid drinking carbonated drinks prior to riding, but Deet 100 may be the only protection from 'the swarm'. Expect some trailside poison oak and prepare as needed. Try using Tecnu before the ride.
Diamond Lake, Miller Lake Nordic
Nordic: Diamond Lake (South Diamond Lake, Thielsen and Howlock) and Chemult (SR97) Sno Parks serve the Mount Thielsen Wilderness area.
The Mount Bailey Tr1451 page includes the Three Lakes Sno Park trails.
Contact the Diamond Lake Ranger District for groom conditions and maps.
The Thielsen and Howlock Sno Parks provide access to Mount Thielsen area nordic terrain, including Howlock Mountain Tr1448, Mount Thielsen Tr1456, Spruce Ridge Tr1458, Summit Rock Tr1457.
The South Diamond Sno-Park trails include Pizza Connect, Horse-N-Teal Tr1481, Outback, Diamond Lake West, Silent Creek, and North Crater. The 1mi Outback Trail is a double-tracked groomed loop that can be accessed at about 0.5mi north of the Sno-Park, which leads to the Broken Arrow CG and ties into the Horse N' Teal Tr1481, Pizza Connect Trail and the Diamond Lake Ski Loop Tr1460.
At the SR97-FR9772 intersection, the Chemult Sno Park provides eastern Mount Thielsen area nordic terrain, with FR9772 to Miller Lake as the primary OAB route, along with some other FR routes which if open connect to Summit Rock Trail 1457.
Also see the Crater Lake National Park page, for hiking and nordic activities.

Mount Thielsen Wilderness
The Howlock and Mount Thielsen TH both serve hikers and nordic skiers on the western flank of Mount Thielsen, progressing through lodgepole pine to mountain hemlock and fir.
Spruce Ridge Tr1458, the creekside Thielsen Creek Tr1449 and Pacific Crest Trail 2000-D connect the two primary ascent routes. Thielsen Camp is at the intersection of Thielsen Creek Tr1449 and Pacific Crest Trail 2000-D.
Mount Thielsen Tr1456 conitinues past Pacific Crest Trail 2000-D, with a Class 5 scramble to the to the spire-pointed peak of Mount Thielsen. Warning: due to exposure there have been more fatalities on this route than have occurred on all the technical routes on the Umpqua National Forest combined.
Howlock Mountain Tr1448 passes Timothy Meadow just prior to the Thielsen Creek Tr1449 intersection, with a slightly steeper ascent to Pacific Crest Trail 2000-D.
Tipsoo Peak Tr1472 is a series of wide switchbacks traversing through a widely spaced mountain hemlock and true-fir forest, with little ground vegetation. The last mile has open dry meadows. The final 500 feet is a scramble along a narrow rocky ridge. Pacific Crest Trail 2000-D is a further 0.3mi unmarked scramble down the eastern slope of Tipsoo Peak.
Maidu Lake Tr1446 and Miller Lake Tr3725 are accessed from SR97 via SR138/FR13 and FR9772. Not shown on the map, Maidu Lake Tr1446 crosses Pacific Crest Trail 2000-D to Maidu Lake and Lake Lucile Tr1459 (Umpqua River headwaters).
This is a remote area, so verify with the forest service that the trails are accessible prior to visiting.
Be prepared for hoards of mosquitos during the late spring and early summer months.
