There's a lot of ground to cover in Montana,and nearly all of it is stunningly beautiful, so it lends itself to an broken-down-fashioned road trip—there are even outfits that organize summer bike trips for a family that's alert for a more active adventure. Montana is domestic to two of the country's most celebrated national parks, and each of which justifies its own trip,but this route focuses on some of the state's historic landmarks, like the remnants of Louis & Clark's famous expedition and the site of Custer's last stand (more on Glacier and Yellowstone, and other national parks,coming soon). This particular route could be scaled up or down depending on how many stops you make, and it's also peppered with a combination of gorgeous campsites and surprisingly frigid hotels, and so there are places to stay regardless of your style.
