At a Glance

  • Compact wilderness with big country character: volcanic peaks, lakes, and meadows
  • Multiple named lakes including Lake Harriette, Eb and Zeb Lakes
  • Remnant caldera of the Mountain Lakes shield volcano
  • Views of Mt. McLoughlin and Klamath Basin from upper ridges
  • Far less crowded than Sky Lakes Wilderness to the north

Overview

Mountain Lakes Wilderness contains the remnant caldera of one of the older volcanic features in the southern Oregon Cascades, predating the Crater Lake eruption by hundreds of thousands of years. The caldera has eroded considerably from its original form but the lake-filled depression at its center and the encircling ridge remnants still define the landscape. The wilderness is compact at 23,000 acres, allowing a full circuit in a single day or a leisurely overnight trip.

The wilderness sits in the transition zone between the Oregon Cascades and the Klamath Basin to the east, giving the higher points on the loop views that span both the volcanic skyline to the north (Mt. McLoughlin is prominent) and the broad semi-arid Klamath Basin to the east. The contrast between the moist lake basin and the drier landscape visible from the ridges captures the climate transition well.

Mountain Lakes Wilderness is one of the lesser-known wilderness areas in the region, overshadowed by Sky Lakes to the north and the more famous Crater Lake nearby. For hikers who want a quality volcanic lake experience without the crowds of Sky Lakes, it is a solid alternative.

This trail lies within Rogue River-Siskiyou National Forest and the Winema side of the co-managed unit.

The Route

Miles 0 to 2.0: Varney Creek Approach

The trail begins at the Varney Creek Trailhead and follows Varney Creek upstream into the wilderness. The lower section climbs through lodgepole pine and mountain hemlock forest characteristic of the eastern Cascades. The creek provides water throughout this section.

The wilderness boundary is crossed at approximately 0.8 miles. A self-issue permit station is at the trailhead (free as of 2026 for day hikes and overnight trips).

Miles 2.0 to 4.5: Lake Basin Circuit

The trail enters the lake basin proper and visits the main lakes of the wilderness interior. Lake Harriette, the largest, is at approximately 2.5 miles. The lake sits in the caldera basin at about 6,000 feet with volcanic ridge walls visible on multiple sides.

Eb and Zeb Lakes and Mystic Lake are reached by short side trails or via the loop's eastern leg. Each lake has designated campsites for overnight visitors.

Miles 4.5 to 8.0: Ridge Return

The loop climbs onto the caldera rim via the eastern loop leg, providing views of the lake basin below and the broader Cascade skyline. Mt. McLoughlin, the dominant Cascade peak of the region at 9,495 feet, is visible to the northwest. The Klamath Basin's characteristic dry landscape is visible to the east.

The return descent reconnects with the Varney Creek trail and follows it back to the trailhead.

When to Visit

July through October. Mid-July is typically when the main loop is reliably snow-free. August and September offer the best combination of warm weather, dry trails, and full lake access. October can bring early snow; check conditions before late-season visits.

Check for fire closures in the surrounding forest before heading out. See current conditions resources.

What to Bring

  • Many hikers carry 2 liters of water. Lakes provide water that requires treatment. Individual needs vary.
  • Insect repellent for July and early August.
  • Layers for cool lake basin temperatures and ridge wind.
  • For overnight trips, review bear canister requirements and the Leave No Trace principles.
  • An offline map. Cell service is absent throughout.

Practical Details

Northwest Forest Pass required (as of 2026). No restrooms at the trailhead. Dogs are allowed and must be leashed in the wilderness. Free self-issue wilderness permits at the trailhead for overnight stays. Group size limits apply; check the trailhead register.

For veterans and active military seeking free pass information, see veteran benefits for national forests.

Getting There

From Klamath Falls, drive west on Highway 66 approximately 8 miles to Keno, then north on Topsy Road and west on Forest Road 3660 approximately 15 miles to the Varney Creek Trailhead. Total drive from Klamath Falls is approximately 30-35 minutes.

From Medford, take Highway 62 east to Highway 140 east, then south on local roads to FR 3660. This approach is longer (approximately 60 miles) but passes through the Cascade foothills.

Cell service ends before reaching the wilderness boundary. Download offline maps and GPS coordinates before leaving Klamath Falls.

Trailhead Parking

Varney Creek Trailhead off Forest Road 3660, approximately 20 miles west of Klamath Falls. Gravel lot with space for 8-10 vehicles. Northwest Forest Pass required (as of 2026).

Frequently Asked Questions

What is the Mountain Lakes Wilderness?
Mountain Lakes Wilderness is a 23,000-acre designated wilderness in the Winema/Rogue River-Siskiyou national forest system. It protects the remnant caldera of the Mountain Lakes shield volcano, a geologically older volcanic complex than the Cascade stratovolcanoes. The area contains numerous lakes formed in the caldera basin and on the surrounding lava plateau.
How does Mountain Lakes Wilderness compare to Sky Lakes Wilderness?
Both are volcanic lake districts in southern Oregon's Cascades, but Mountain Lakes is significantly smaller (23,000 vs 116,000 acres) and receives far fewer visitors. The character is similar: volcanic terrain, numerous lakes, subalpine forest. Mountain Lakes feels more intimate and is better suited for a first wilderness backpacking trip in the region.
Which lakes does the main loop visit?
The Varney Creek loop visits Lake Harriette (the largest lake in the wilderness), Eb and Zeb Lakes, and Mystic Lake, along with several smaller unnamed ponds. The loop circuit provides access to most of the primary lake destinations in the wilderness.
Are fish present in the Mountain Lakes Wilderness lakes?
Yes. The lakes support wild brook trout and have historically been stocked. Current stocking status varies; check current Oregon Department of Fish and Wildlife regulations before fishing. A valid Oregon fishing license is required.
When does snow clear from the Mountain Lakes Wilderness?
Snow typically clears from the main wilderness by mid-July. The Varney Creek Trailhead is at lower elevation and may be accessible earlier. Check trail conditions with the Klamath Ranger District for current snow coverage in early season.
