Washington State Fish and Wildlife reserve that was logged about 15 years ago, judging by the height of softwoods and assorted vegetation, a nice simple path well carved out by the local ATV users, some semi-technical stuff between different logging roads and quite a few long climbs separated by flats, pretty open on the trails, and there is a pond that has a fairly unused quad trail going to it.
How to get there:
Tenino, small town I know. exit 95 Southbound off I-5 into maytown, take the first right off the exit ramp, stay on that road that parallels the tracks, until Millersylvania state park in on the Left, take the right, onto Tilley road, turn Left on to 143, that turns into Mcduff after the tracks, again, follow mcduff past the High school softball field onto Sussex, park at the Daves marketplace Lot and ride sussex to Churchill Rd there will be a WDFW sign and a chained up road, ride around the post and have fun...
coming northbound on I-5, exit 88 south sound speedway, just follow that road until Tilley rd and that will lead you to 143, on the right, then go to the store, and park.
