Overview

The Sylvania Wilderness is the crown jewel of Ottawa National Forest, and this 7-mile loop provides the best single-day introduction to its old-growth forests and pristine lakes. The circuit circles Clark Lake through ancient sugar maple, yellow birch, and eastern hemlock, passing lakeshores that have never been logged, developed, or mechanically disturbed. The trees here are among the largest of their species remaining in the Great Lakes region.

A free permit is required for entry (as of 2026). Dogs are not allowed. The trail is gently rolling with only 350 feet of total gain.

The Route

Miles 0 to 2.0: Entry forest and first lakeshores. From the entry station, the trail descends through a transition forest before entering old-growth character around mile 1.0. The sugar maples grow massive here, their trunks 3 to 4 feet in diameter. Yellow birch with their peeling silver-gold bark stand in the wetter ground. The first lake glimpses appear around mile 1.5 through the trees.

Miles 2.0 to 4.5: Clark Lake circuit. The trail follows the west and north shores of Clark Lake, the largest body of water in the wilderness. Designated camping sites with tent pads and bear boxes are positioned around the lakeshore. The water is clear to 20 feet of depth. Loons breed on Clark Lake and are typically present from May through September. Bald eagles fish here regularly.

Miles 4.5 to 7.0: Old-growth return. The eastern and southern sections of the loop traverse the densest old-growth forest on the route. Fallen trees create large woody debris on the forest floor, and the absence of logging history is apparent in the uneven-aged structure of the canopy. The forest feels genuinely prehistoric in sections. The trail returns to the entry station through a final stand of old-growth hemlock.

When to Hike

Late September through early October is the unqualified peak of the year for fall color. The Sylvania's sugar maple canopy turns gold, orange, and red with stunning intensity. This is the most popular period; permits should be reserved in advance through Recreation.gov.

June through August is the primary season. The wilderness is at its greenest. Black flies (June) and mosquitoes (June-July) are the main nuisances.

What to Bring

Many hikers carry 1.5 to 2 liters of water; lake water is available but requires treatment. The wilderness has no developed water sources inside. Insect repellent is essential in early summer. The forest canopy keeps temperatures cooler than open terrain, but a light layer is worth bringing for lake-edge sections.

Trailhead Access

The Sylvania entry station is on US-2 west of Watersmeet, near the Wisconsin border. From Ironwood, head east on US-2 about 30 miles to Watersmeet and then follow signs to the wilderness entry station. Paved road to the entry station.

Nearby

The Ester Lake Trail accesses another backcountry lake in the Sylvania unit with similar old-growth character. The Bond Falls Loop is a very different Ottawa experience, worth pairing with a Sylvania visit if time allows. Follow Leave No Trace principles throughout the wilderness; the old-growth ecosystem is fragile. Review our how to get a national forest camping permit guide if you plan an overnight trip.

Trailhead Parking

Sylvania Wilderness Entry Station off US-2 at Watersmeet. Paved lot at the entry station. Free permit required at entry (as of 2026). Pick up permit at the entry station or reserve through Recreation.gov.

Frequently Asked Questions

What permit is required for the Sylvania Wilderness?
A free day-use permit is required to enter the Sylvania Wilderness (as of 2026). Permits can be picked up at the entry station on US-2 near Watersmeet. Overnight campers require a separate camping permit, also free but limited in number per lake site. The permit system limits daily entry to protect the old-growth ecosystem from overuse. Permits are available through Recreation.gov for advance booking or in person at the entry station.
Why are dogs not allowed in the Sylvania Wilderness?
Dogs are not permitted in the Sylvania Wilderness as a result of the federal wilderness designation, which restricts pets to prevent disturbance to the wilderness character and wildlife. The adjacent Sylvania Campground and some non-wilderness national forest trails in the Ottawa are dog-friendly. If you are traveling with a dog, check with the Ottawa National Forest ranger district for nearby trail options.
What is the best lake to visit in the Sylvania Wilderness?
Clark Lake is the largest and most accessible lake in the Sylvania Wilderness, with designated camping sites around its shoreline and excellent fishing for smallmouth bass and northern pike. The loop described here circles Clark Lake and passes through some of the best old-growth forest in the wilderness. Loon Lake and Cub Lake are other popular destinations accessible on extended trips deeper into the wilderness.
