Coalton Trail

Trail Meter: 

When you get to the Coalton Trail, you couldn't be blamed for thinking it looks a lot like a gravel road. While it lacks in features or much fun, it's a key connector in the Dirty Bismark loop, and is also a great way for those in the Superior/Louisville areas to get of road and into the rest of the Marshall Mesa trail system.

Wide, flat, and gravel is the rule here. The exception is the one main climb, which is often a bit rutted and provides the only potential challenge.

Numerous muddy spots from 7/7 rain. Someone in a vehicle drove this last night or this morning and left massive ruts along the section from HP to the big hill down the trailhead.

The green is starting to turn brown... but plenty of wildflowers! Go get some!

wildflowers are still going off... get it while it's green!

Now it's green... It's awesome... Go get some!

Wildflowers are popping! Go there!

This is the best time of year to be riding this Trail... Get some while it's still green...

Trails in great shape, but watch out for snakes! I almost ran over one on this trail. It was reddish like the dirt on this trail, but pretty big. Scary! I still have the heeby jeebies!
