Trail Overview

This trail geometry is now updated to avoid the road closure near the Wisconsin/Michigan border. The Seven Hour Plane Crash trail can be run from Crandon, Wisconsin, or from Copper Harbor, Michigan, and travels all the way to Michigan's Upper Peninsula. A particularly quiet trail, you can expect ruts, lots of forest roads, some washboard sections, and a potential water crossing. Copper Harbor High Rock Bay camping area is busy but has great views. The trail into the High Rock Bay outside of Copper Harbor is also very rough with deep ruts and potholes that will swallow a minivan.

Difficulty

Beware of the water crossing as it can be over 12 inches deep.

History

Originally this trail was put together by someone who used to desert race. They called Baja races "all-day plane crashes." This trail is about 300 miles long, which takes about 7 hours nonstop. There was a road closure on the trail near the Michigan/Wisconsin border but the trail geometry has since been updated to avoid that closure.

Ran this trail recently and did not need 4x4 at any point. Conditions were mostly straightforward, with several water holes along the way, but none were deeper than about 8 inches during my run. The road surface is rocky in sections, so I’d recommend airing down for comfort and to keep things smooth. Overall, this is a great trail with a fun mix of terrain and scenery. Solid beginner-friendly route and a good time if you’re looking for an easy day out with some light adventure

Did the entirety of the trail over 2 days with my buddies in my ‘91 Jeep MJ. Great time, 97% of the trail was super easy just gravel roads- The last mile to high rock point was probably a 5/10. One water hole was over 20” deep, had some big boulders as well.

the portion of this trail that runs from highway 41 to High Rock Bay is only for side by sides and 4 wheelers, the correct way to get to High Rock Bay is to continue on highway 41 into Copper Harbor, then go east following highway 41 until it ends, follow the High Rock Bay trail then there's a left turn onto the Rocket Range trail, at some point there's a split to go left, if you keep to the right you will head to High Rock Bay, left takes you to the rocket pad.

A good portion of this trail is on state Route 41 which is paved and doesn’t allow SXS access. I feel this trail is improperly marked.

Started at Crandon, WI and made our way north. Trail consists of a combination of gravel, two track and paved roads. Basswood road was still closed for bridge work as of 8/31/25. Trail conditions change drastically once you turn off US41 onto Burma road especially during or after rain. Most water holes encountered were on High Rock Bay road. Never used 4WD at any point on the trail.

(road was closed for road work by golden lake lookout see picture for how to get around this. as of 8/20/25) pretty easy trail mostly just gravel roads till you get to outside of copper harbor. after copper harbor going to high rock bay its little wash board and has big puddles to drive through would get worse with rain but went through them in 2wd. high rock bay is surprisingly busy even on a Wednesday night so have a back up spot picked out to camp just in case. good trail and copper harbor and eagle harbor are very beautiful

You may want to air down a bit for this. most the gravel roads are fairly rough. the last couple miles into high rock bay had quite a few water crossings, which im guessing will be worse when im back up in the end of August. I'll give another report at that time

46.05698 -88.92113 has some deep water and mud. Our Jeep on 35’s and our friend’s square body Chevy on tons with 37’s only made it about 20 feet. Just avoid it unless you’re gonna be the 1 guy who thinks you’ll make it. 46.18336 -88.78730 has a bridge out but easy to go around on some main roads. Side note: “The Loft” on Airbnb in Crandon WI is a great place to stay and only minutes from the trailhead.

there's a soft hole after the end of Kaine Lake RD. there's a section labelled 'winding trail' where the holes just get softer and softer. this is the lowest point and the most difficult spot where everyone gets stuck. the construction company had diverted a creek from there, so it should harden up over time. I highly recommend a winch. this is a remote trail. I slept from 5am to 12 without anyone passing by. had to hike for help.

The first portion of the trail traveling north is passable with 12-18” deep water pools and solid bottoms until the trail turns east. Just before this turn (46.05648, -88.92135), the water is 12” deep but below that is 12” of mud and it only gets deeper as the trail continues lower in elevation. Fun up to that point as long as you’re with a group for any required self-recovery.

Kaine Lake section avoid as others mentioned. Lots of mud and deep water crossings. We got stuck badly in one of the water crossings and had to winch out. If you do not have a winch or high clearance definitely recommend bypassing
