Green Mountain State Forest is a nice weekend ride for ATVers who live close by. This would mean any ATV families in or around Seattle. There is a campground here for weekend camping, so any ATV family or individual can make the most of your riding time. This is a fun time for summer vacations when kids are out of school. The area is open all year, but restricted to ATV and other vehicle use to June 1 through October 15. This is for trail maintenance purpose, which any ATVer will understand as necessary for optimum ATV enjoyment.
Green Mountain has a group of shorter trails with very nice ascents and descents - there are areas with sharp, but short elevation levels. The area is well marked for everyone's benefit, ATV user and all others, which includes bikes, hikers, and horseback riders. This is why the park in open for ATV uses on weekends; these other groups are there during the week.
There are gravel roads and dirt paths. The views are really fun to come up on. There is Seattle and the Cascades on one side, and off on another stretch you can see Hood Canal and the Olympics. The trails drift back and forth through the camp area so you are always close to your base. Stop at the top for a view and some lunch. Green Mountain Park has a lot going for it; All in all, a very favorable spot to take an ATV out for a spin.
