Tourists wait hours to see Kitch-iti-kipi, Michigan's Big Spring

It's one of Michigan's most alluring natural attractions, according to the state Department of Natural Resources.

Located in Palms Book State Park, the lake was nicknamed Mirror of Heaven by the Ojibwe for its crystal clear, teal-colored waters, which remain a constant 45 degrees and rarely freeze in winter.

Here's what you need to know if you're headed to the Big Spring:

Where to find it:

It's located inside Palms Book State Park, which is open 8 a.m. to dusk. It's a 15-minute drive from Manistique and an hour from Munising, home of Pictured Rocks National Lakeshore.

There is an accessible path from the parking lot to the observation deck-raft.
