Munising Falls

Munising Falls is cut into the Munising Formation, a Cambrian-age sandstone that the Michigan Geological Survey dates to roughly 500 million years ago. The formation was deposited along the shoreline of a warm, shallow sea that covered much of what is now the Upper Peninsula; the rock visible at the falls is mostly fine to medium quartz sandstone with a thin shale interbed near the lip.

The mechanic at work is straightforward soft-rock undercutting. The cap at the lip is more resistant than the sandstone face below it, so Munising Creek wears the lower rock back faster than the top, and the curtain develops a small overhang. The recessed alcove behind the falls, which the summer walk-behind path follows, is the visible cumulative result of that undercut, and the broader Cambrian package the falls sits in is the same sequence that produces the painted cliffs at the Pictured Rocks themselves. The cliffs are differently colored because they sit at the Lake Superior shoreline where mineral-laden groundwater seeps through the sandstone face; Munising Falls is in the forest above the lake, with no equivalent seep system, so its sandstone reads warm tan to orange instead of the famous green-blue-orange streaks.

The most-asked Munising Falls question after “how tall” is “can you walk behind it.” The honest answer is yes, in summer, on a wet and uneven informal footpath. The path crosses the back of the sandstone alcove on a narrow stone-and-dirt ledge inside the undercut; from the lower viewing platform, take the short stairs up and to the right and follow the worn track around the back of the curtain.

The path is reliably open from roughly mid-June through mid-September, when the rock is dry and the spray is light. In spring runoff the footing is too wet and too slick to be safe; in winter the alcove fills with ice and is closed. The NPS does not maintain the path as a graded trail and posts no signage promising access, so treat it as a seasonal informal feature rather than a guaranteed amenity. The amphitheater is small (you are inside the rock, not in a cathedral chamber), the spray is real, and your shoes will be wet for the rest of the day. It is still one of the few walk-behind waterfalls in the entire Upper Peninsula that does not require off-trail scrambling.

In a normal Upper Peninsula winter the entire 50-foot drop freezes into a hollow ice column with running water continuing inside it. The freeze typically completes in the second half of January and holds through mid to late February, with the most reliable column visible from the lower platform between roughly January 25 and February 20 in cold years. The City of Munising and the regional tourism office actively market the winter falls because it sits five minutes from a paved highway and three minutes from a heated visitor-area lot, which is unusual for a U.P. ice climbing destination.

Munising itself is the unofficial ice climbing capital of the Midwest. The Pictured Rocks cliffs along Sand Point Road and the curtains farther east at Curtains, Dryer Hose, and the Section 28 routes attract climbers from Chicago, Minneapolis, Detroit, and Toronto for the annual Michigan Ice Fest, usually held the second weekend of February. Munising Falls itself is not a regular climbing route (the column is short and the alcove is busy with visitors) but the falls is the easiest place in the U.P. to read the ice season firsthand before driving out to the climbing zones.

Four named waterfalls in Alger County share variations of the Munising name or address, and visitors arriving on the M-28 corridor regularly arrive at the wrong one. The correct disambiguation:

• Munising Falls (this page). 50-foot plunge, paved 0.4-mile out-and-back, trailhead at 1505 Sand Point Road at the Pictured Rocks visitor center.
• Miners Falls. 50-foot plunge inside Pictured Rocks on the Miners River, 12 miles northeast of town on Miners Castle Road. Different trail (1.2 mi round trip, dirt, stairs to a lower viewing platform), different watershed, much higher flow.
• Tannery Falls. 40-foot multi-step waterfall on Tannery Creek inside the city of Munising on Washington Street. Free, short, easy to add to a city stop.
• Scott Falls. About 20 feet, road-side on M-28 in Au Train Township, 10 miles west of Munising. Two-minute walk from the highway pullout, also a walk-behind in low flow.

If your map app is routing you to a falls in the Munising area, check the street address first: Sand Point Road is Munising Falls, Miners Castle Road is Miners Falls, Washington Street is Tannery Falls, M-28 in Au Train is Scott Falls. All four can fit in a single day with the Pictured Rocks boat tour.

The Munising Falls trail is one of a small number of fully accessible waterfall paths inside a national park unit. The current alignment is paved from the Munising Falls Visitor Center to the lower viewing platform, with a near-level grade and a surface that meets ADA standards. AllTrails records about 49 feet of elevation gain across the round trip, almost all of it as a gentle rise rather than a stairway.

The trail has not had an uneventful decade. In April 2025 the NPS posted a closure notice after about 75 feet of the paved tread washed out in a spring storm; the trail has been repaired and reopened, but the closure log is a useful reminder that the creek can move surprising amounts of bedload in heavy runoff. The walk-behind path and the upper deck involve stairs and unpaved footing and are not part of the ADA-accessible route; the agency does not certify the alcove for wheelchair or stroller access. If accessibility is the reason you are visiting, plan around the lower platform alone and you will get the strongest head-on view of the falls without leaving the paved surface.

The most popular activity in Munising is not the falls but Pictured Rocks Cruises, the boat tour out of the Munising city dock that travels along the painted cliffs east of town. The cliffs themselves are mostly visible only from the water; the few hike-in viewpoints at Miners Castle and Chapel Beach show isolated features rather than the full painted wall.

The natural pairing is a morning at Munising Falls (15 to 45 minutes plus visitor center time) followed by the 2.5-hour Pictured Rocks classic cruise that leaves several times a day from late May through mid-October. The dock is 1.5 miles from the visitor center, about a 4-minute drive. If you have a full day in town, add Miners Falls (90 minutes including the drive) and Tannery Falls (30 minutes), and finish at the Munising waterfront for sunset over Grand Island. Boat-tour tickets are bookable in advance through the cruise operator; summer weekends sell out a week or more ahead.
