Mark Twain National Forest

As large as the Irish Wilderness is, it is dwarfed by the 1.5 million acre Mark Twain National Forest of which it is a part.

The Mark Twain National Forest is a land of limestone mountains of surprising steepness, clear-rushing streams perfect for canoeing, and a diversity of plant life as remarkable as it is endlessly interesting. Although wilderness areas are closed to mechanical transportation, more than half of the 742 miles of mark Twain’s trails are open to mountain bikes. There are abundant choices for canoeing, hiking and even scenic automobile drives.

For more information on hiking trails, canoeing and guide maps, visit the Forest Service or GORP.
