Anyone done the Cascade Loop in Washington state?

For an extremely scenic crossing of the Cascades, you can't beat U.S. 12 from Lewiston- Clarkston, Idaho to Lolo Pass in Montana. If you can hit it during fall color, all the better.

A Lake park was damaged during the fire.
Rockport has the steel-header park that has some basic hook ups.
Nearly every dam on the Columbia has some sort of recreational park that has RV sites.
If you have not been in this part of WA, take a side trip to Grand Coulee Dam.

I can't help with commercial campgrounds. But for others (working off the top of my head):

Washington State Parks (check the state website):
http://www.parks.wa.gov/838/North-Central-Region
- Lake Wenatchee
- Lincoln Rock on the Columbia
- Alta Lake near Peteros (some fire damage)
- Perrygin Lake near Winthrop
- Rockport (day use only) (very old growth)
- Rasar (on west side of WA20)
- several on Whidbey Island
(there may a couple of county operated parks along the Columbia River)

National Forest (western ones start closing in Sept; eastern ones remain open for deer hunting season)
- several along US2 west of Stevens Pass
- several east of Stevens Pass
- several along WA20 east of Washington Pass

National Park
- several in North Cascades NP, west side. Cheapest of the public campgrounds.

We've done it multiple times. It is nice, although between the fires and mudslides the place is kinda a wreck at the moment. It'll probably be better when you come up. Most everything along there is pretty RV friendly. Some of our favorite spots are Smallwoods Farm, Wenatchee Confluence State Park, Perrygin Lake State Park and Winthrop.

Great loop! Not sure which pace to are going to start. I would wait until late Sep so the trees should be in good fall colors. Several little towns to stop at. Leavenworth in a Bavarian theme town. Winthrop is a western motif.
Fires around Peteros has screwed that area up for years to come.
Verify that any campgrounds in eastern WA are operating in Mid-late Sep as some close down Labor Day.
On the WA 20 side make sure you watch your fuel. Not much between Sedro Wooley and Winthrop.

This is a route promoted by various Chambers to promote business. It uses US2 and WA20 to cross the Cascades, and US97 (and another state road) to connect them on the east side. In the more populated west side there are various options, including I5, WA9, and the drive along Whidbey Island.

Most of these roads have been discussed on this board.

The latest was about a temporary closure on WA20 due to a mud slide last Sunday evening. The east end was also in the news with fores fires. All roads are open now, but you will see fire scarring.

There was also a recent thread asking about the fastest route from Calif to the North Cascades Park - which WA20 passes through.

Any specific questions?

What kind of camping do you want? hiking? other recreation?
