We don't offer snowmobile rentals in Estes Park. Nobody does actually. We just don't get enough long term deep snow pack for it. We did rent snowmobiles for a few years. As it turned out, 95% of our customers preferred ATV and razor riding in the snow instead. It's a heck of a lot of fun. 

However, if you have your heart set on snowmobile rentals and / or guided tours, check out On the Trail Rentals in Grand Lake, Co. If you REALLY want to have fun in the snow, consider an ATV Rental. They're a blast!
