Pictured rocks, near Munising, has a few jumble cliffs, altho most are over 150 feet and would be suicide, the jumpable drops are huge in the 60-70 foot range, and are limited to a few spots. The return hike to the top is also pretty long from what i have heard.
Black rocks near downtown marquette is a shorter hike back to the top and the drops are much more manageable btwn 10-30 feet. I believe these cliffs are just north of marquette in a city park?
There are literally thousands of jumpable cliffs along the Superior shoreline, and many more along inland lakes, just look at a map for some rocky topography near lakes and streams and go find some!
