My wife and I might be going out to Denver. I was wondering if there is anyplace near by where we can rent sleds, gear and go on a guided tour for one day. I have never been there. I would prefer a guide with longtracks to go offtrail but I'm open to suggestion. When does the riding season usually start? Thanks

We rented an M8 from this place for about 5 days.

Pretty happy. They provided all the oil and extra belts, helmets etc.

I think this was the only place that we could find that rented sleds larger than a 600.
