Description

An inland sea arch carved by the crashing waves of Lake Superior, Suzy's Cave is one of the top destinations for a day hike from Rock Harbor.

Formed "some 4000 years ago when water levels were higher," this classic hike in Isle Royal NP doubles as a shorter version of the difficult 10-mile trek to [Mount Franklin](https://fatmap.com/routeid/2707774/mount-franklin/). The cave can be accessed via Tobin Harbor Trail or Rock Harbor Trail.

A spur trail between the two offers access to view the cave.

While "Rock Harbor Trail is difficult and includes rocks and roots," the park suggests that Tobin Harbor Trail is both easier and "significantly smoother." Seen here, this loop pairs both, giving you the option to hike either trail in either direction.

For those seeking a longer day hike or even an overnight trip, make your way to [Mount Franklin](https://fatmap.com/routeid/2707774/mount-franklin/) instead.

Suzy's Cave can be easily incorporated into the route, and overnight camping is available at [Three Mile Campground](https://www.nps.gov/isro/planyourvisit/trail-accessible-campgrounds.htm). [Source](https://www.nps.gov/places/suzy-s-cave.htm)
