Federation Forest State Park is a day-use natural area with 619 acres of old growth evergreens. Located along the White River, the park provides visitors with 12 miles of hiking trail, three interpretive trails, an interpretive center with a gift shop and four picnic areas.
A great trail full of gorgeous views. It's pretty easy and only takes about 1 1/2 hours to get around, and there is a nice stopping place at about the halfway point for a break. Easy enough for the kids to tag along but just enough of a climb and distance to feel as though you're getting some exercise in.
I wouldn't really consider this a hike, since there's no elevation gain at all. It is a really nice place to take a leisurely stroll, or to bring littler kids who might not be able to handle more strenuous hikes. I went in March, and it was muddy in a lot of areas, but also fairly deserted, which was kind of nice.
I will still provide a little analysis, but let me say upfront that the trail is BORING, and you should definitely SKIP it. If you want to move on to another review, go ahead. For any of you still reading this, there are much better trails in the area (Snoquera & Skookum Falls are two that come to mind) and even before climbing on 410 near Mount Rainier, I would even recommend the lackluster Mud Mountain Rim Trail (right outside of Enumclaw) over this catastrophe. The trail(s) basically wind through an old growth forest that isn't even close to the sheer beauty of the Hoh Rainforest. The only real feature is a trail that leads you to the White River. Considering you hug the river all the way up to Mount Rainier there are way better spots to access it. This trail was a complete waste of time, I ended up heading up to the park and did some hiking around Chinook Pass just to make the drive worth something. I promise you, drive on by, you are not missing a thing!
the bottom trails are great, flat and lead to views of the river. the top trail is pretty overgrown from people not using it, it's a little more intense and the trail ends with down trees. you either have to go back or make your own trail to get to the road.
