Ahtanum State Forest

The Ahtanum State Forest is a very large area west of Yakima, Washington. US12 is near the north boarder, Rimrock boarders the west and the Yakama Indian Reservation boarders the south. You can ride ATVs and dirt bikes on all the Green Dot trails and roads. In the winter some are close and groomed for snowmobiles.

There are some great views from on top of the ridges. Eagle Nest Vista is a great view overlooking the North Fork. On a clear day from Darland Mountain (6981′) you can see Mt. Rainier, Mt. St. Helens, Mt. Adams, Mt. Hood and Mt. Jefferson. On the Divide Ridge trail 613 you can down on Rimrock Lake and get a great view on Mt. Rainier. Some of the hardest 4×4 trails are long Divide Ridge. Those trails are called Rimrock.

The Grey Rock Trail is a single track trail that begins at the Tree Phones Campground. It ties with a Forest Service trail 613. Some sections have been made for ATVs to use.

Jumpoff Tower (5670′) is at the northwest point of the Ahtanum. It has a great view over looking Rimrock and US12.

Blue Lake (6202′) is a great place to stop for lunch. It is on a 4×4 trail off the North Fork Ahtanum Creek Road on the way up to Blue Slide Lookout (6785′).

Green Dot System

The Green Dot system means only roads and trails with Green Dot road markers are open. You can ride on all the Green Dot roads and trails in the Ahtanum unless it is posted closed or is a trail being groomed for snowmobiles.

Green dot roads are a cooperative road management program between public land management agencies and private landowners. In the Green Dot Road Management System all roads in an area are closed unless posted open with a green dot. Roads identified as “green dot roads” on green dot maps and posted with a round green reflector on white markers are open to public motor vehicles. Green dot maps of most areas are free and available at WDFW and DNR offices. Some maps and agreements are being reformatted due to current land exchanges and are out of print right now.

Except for roads open by green dot designation, all roads and trails are closed to all wheeled motor vehicles including ATVs. Violators will be subject to prosecution pursuant to W.A.C. 232.12.187. Closing sensitive areas helps protect fish from sediment running off of roads, migratory routes of big game, wildlife habitat, and timber and road resources while allowing for safe and fun recreation opportunities. The green dot roads are meant to remain at a net amount of miles, so when one section is removed from the management agreement, another may be added of equal length. Roads designated as green dot can change as harvest or sites are identified which may need protection or rehabilitation. We appreciate help from users in maintaining and educating about our green dot system!
