One of the most popular ways to explore the Rocky Mountain region is aboard a motorized vehicle. Whether it is a Jeep, a Hummer or an ATV, there is something to be said for riding off into the Rocky Mountains aboard a powerful 4-wheel vehicle. Jeeps typically allow for 4 passengers, and usually feature an open top. Jeeps are steel-reinforced, and knowledgeable guides navigate them through the off-trail terrain you will explore. Hummers can fit up to six passengers, and have a wider wheel base. Both vehicles allow passengers to sit back, enjoy the scenery, flora and fauna, all while learning about the vistas and history of the area from a knowledgeable guide. This is a great alternative to hiking or biking, as it allows a laid-back, exertion-free approach to seeing all that the Rocky Mountains have to offer. ATVs (or All Terrain Vehicles) are a more involved way to explore 4-Wheel-Drive trails. ATVs are made to ride anywhere including mountains, flatlands, sand dunes and rocky, muddy roads. But most riders find ATVs most useful in mountainous terrain because almost no other vehicle can ride through such terrain with the same dexterity. The rider sits on and operates these vehicles like a motorcycle, but the extra wheels give more stability at slow speeds, allowing more advanced operators to truly explore the landscape. Though no prior ATV experience is typically required, riders should feel comfortable navigating a powerful, motorcycle-like vehicle prior to hitting the trail on an ATV.
