Colorado Rockies

It depends on what you want. My preference, in season, is the Gunnison valley, Black Canyon and the reservoirs upstream (Curecanti NRA). I like to see the geology, and I like being on fishable waterways. These are along US-50 on the west side of the continental divide.

For these places, rig size is pretty much irrelevant.

If your interest is the Rocky Mountains specifically, that would be from Colorado Springs north to Rocky Mountain NP, as the mountains are most impressive on the Front Range. Once you are up on top of them, the mountains don't make as much of an impression.

we looked into Cherry Creek but ended up at Chatfield. Chatfield actually worked out good as far as being close to major traffic arteries to venture for the day. So much to see out there, we love visiting the area. I guess it all depends on what you will have to travel around in while staying as to what you can see and do. Places we went, Mount Evans, Pikes Peak, RMNP via the Trail Ridge road, Royal Gorge(canyon city). And quite the interesting restaurant in Sphinx Colorado called the Bucksnort Saloon. Many more quick stops just being out and about.

Durango-Silverton-Ouray

Anywhere on Route 50. From Canyon City, over Monarch, to Grand Junction.

Gunnison-Lake City-Creede.

That is about two years worth of Summers without getting North of the Interstate.

For RMNP I like Grand Lake over Estes Park... tourist trap. Plenty of private and public CGs to choose from. Timber Creek inside the park is new and a good example of why you do not want the government to design something. In a cleared area from dead pines with only 6-8 big rig sites (rocks blocking many others) and one of the two bath houses is a long way from the tent camping area.:S
What outdoor activities do you like and I'd not call 36' a big rig???

We are planning our trip for July we always stay in Denver at cherry creek and plan to do that again but haven't visited rocky mountain national park. We have been to Durango and Colorado Springs. We are open to any type of new adventure.

Lots of variables. When are you looking at coming? Is there anything in particulair you wanted to see? Pretty good sized area youa re talking about.There are lots of options for larger rigs.
