Overflow is the biggest, fastest downhill trail in Copper Harbor. The trail features massive rock rolls, an impressive gap jump over The Flow, ripping berms, an exposed rock slab called Dino Rock, the Diving Board, and finally a gigantic rock roll/cliff at the bottom commonly referred as the Pants Drops.

Although the Gap Jump has a ride around, don't believe that the challenges are over. Only plan to ride this trail if you are an Expert

Access Info

The trail begins at Brockway Mountain Drive and ends at a corral with The Flow at M-26.

      My favorite trail in the entire UP. This one has it all - gaps, tables, berms, chunk, rock slabs, drops, and plenty of speed. Man Pants and the 'over Flow' gap after the famous curved wood ramp (that gives this trail it's name) are big features and definitely deserve a scout before being hit.

      The motion to require CHTC to obtain the new $5,000,000 liability policy by Sept. 1st, 2021, was initiated by Rajala.. the lone Republican on the board. Of course supported by the rest, but to say it was just "Biden voters" is pretty daft and ignorant. It's bureaucracy altogether that ruins stuff, not one side or the other.

      We hope you've been enjoying Trailforks!
