We recently spent some time in a place no Americans seem to know about, Flaming Gorge, Utah. This is a piece of the Uinta Mountains (bet you didn't know about this mountain range, which predates the Rockies!). A large reservoir was built here in the 60's. It is located off the beaten track in NE Utah near the Wyoming and Colorado borders. As you explore it you will find an incredibly deep canyon colored red with rocks almost a billion years old. 1,0350 feet down from the top are deep waters from the Green River. The canyon is ringed with wilderness mountains and trails at high elevations and sagebrush at low elevations. Camping is offered for tents and self contained RV's, but you can stay in private campgrounds nearby with electricity and water. There is also a lodge with really good food called Red Canyon Lodge. There are boats and rafts available for the reservoir and the river below the dam. Because the river has 1 and 2 level rapids you can float down it without a guide, and fly fish for trout if you wish.
This great place is relatively uncrowded, unlike the other Wyoming, Colorado, and Utah national parks. It is an hour south of highway 80 and an hour north of Vernal on 191. Everyone who comes there says "I didn't know about this place". Many Europeans visit it, though. They seem to know that its a good place to stop on their way to Yellowstone, to the Tetons, to Arches, or to Dinosaur. Around Flaming Gorge are isolated valleys where you can see places where outlaws such as Butch Cassidy and the Sundance Kid hid out from the law. Just know you need to drive there on dirt and gravel roads which are in pretty good shape, even for small RV's and cars.
