Loon Lake

Overview

This is one of the park’s easiest inland lakes to reach: a small, very deep, roughly 93.6‑acre lake tucked right off M‑22 near the Platte River corridor. It’s peaceful, ringed by forest, and makes a mellow counterpoint to the busier river just downstream.

What You’ll Do

Most people come to launch a canoe, kayak, or SUP, cast a line from the fishing dock, or cool off along the small sandy edge. If you’re floating the lower Platte toward Lake Michigan, you’ll cross Loon Lake on the way—just remember the lake itself has no current, so you’ll need to paddle across.

Vibe & Scenery

Expect clear water, a quiet shoreline, and that classic northern Michigan feel—glacially carved basin, sandy patches underfoot, and tree‑lined views. It’s a low‑key spot to linger, especially if you want a breather from the river crowds.

Wildlife

Keep an eye out for ducks and other waterfowl cruising the surface, songbirds working the edges, and fish rising in the evening. The calm water makes it easy to spot surface activity.

Access & Amenities

A large paved lot sits just off the highway, with a paved boat launch and a fishing dock right by the water. It’s straightforward to unload and get on the lake quickly. There’s no campground at the lake itself; camping is available elsewhere in the Platte River area.

Know Before You Go

Because the lake is deep and still, it feels different from the river—great for a quiet paddle, but a surprise if you expected a push from the current. If you’re tubing, bring a paddle or be ready to arm‑paddle across. Peak summer weekends can draw crowds, especially midday.

Best Time to Visit

Go early on summer mornings for glassy water, fewer people, and soft light for photos. Weekdays are usually quieter than weekends, and evenings can be lovely for fishing and watching birds work the shoreline.
