Any ATV group looking for ATV sites around which to plan outings, take a look at Washington State. Washington has a broad terrain spectrum from which an ATVer can choose to plot a course. They have several sand dune areas, much mountainous areas, and, for those just in love with the forest landscape, there is plenty there from which to pick to be surrounded by trees. Anyone who lives within a day of one of the many ATV sites, plan a weekend, or a day trip. If you live out of state, plan a three-day weekend, or even plan a week vacation in Washington State. Take in the ATV friendly national and State Parks.
Also, an ATVer has the choice of season there. Spring, summer, or fall are all great times to ATV there. There are even cooler times where a light dusting of snow can test your ATV mettle. The ATV runs are not as grueling as, say, a stark desert run, nor are they family unfriendly - in the sense that the landscape is dangerous due to the extremes in heat. Washington State has all the great places families want to be on an ATV, and it's a great place for younger family members to take some learning runs.
For anyone in the family who doesn't care to ATV the day away, there are a number of things to do. You can spend time in any number of towns taking in sites, you can camp, river raft, rapid shoot, fish, swim, hike, mountain bike, and so much more. Washington is an ATV family state.
