About Agate Falls

Agate Falls is a 40-foot block in Michigan, on Middle Branch Ontonagon River.

It's fullest after rain, and flow can drop off during dry spells — plan around recent weather.

Plungeworthy rates Agate Falls 7.3/10 — worth the drive. The score weighs its scale, how confidently it's mapped, and its character.

What you'll find

Bond Falls' upstream sibling: the same Ontonagon water dropping 40 feet under a railroad trestle, reached through a tunnel beneath the highway from an old-fashioned M-28 roadside park.

Getting there

Trailhead: M-28 roadside park near Trout Creek
Parking: Paved roadside-park lot (closed in winter)
Road: Paved M-28
Hike: 0.5 mi round trip (easy to the platform; the unofficial path to the base is a 70-degree bad idea)
Heads up: The under-highway tunnel and trestle view are half the charm.

When to go

Spring flow; fall fills the little lot with leaf-peepers.

Rules & fees

Fee / pass: None — roadside park
Dogs: Leashed
Camping: State forest campgrounds nearby
Warnings: Skip the scramble to the base — the slope has earned its reputation.

Where it is

Before you go

The pin marks the feature, not a trailhead or a legal route in. Some sit on private land or need a real hike, and conditions change with season and rain. Check local access, don't trespass, and never enter water — hot or cold — where it isn't safe.
