Excellent experience! We had two rentals, one with a 13-yr old passenger, and all had a great time. The booking and confirmation process was convenient and easy and they sent plenty of information prior to arrival so we were well-prepared. The scenery while riding through the national forest is magnificent. We've done snowmobile tours on other vacations and this one topped them all by FAR. It was well worth paying for a guide, ours were super nice, knowledgeable, accommodating of all skill levels, and toured us through some beautiful areas that would not be accessible if you go with just a rental and a map. Tips: 4wd is pretty much mandatory to get to the meeting point and be sure to bring some extra cash to tip your guide.
