Washington - North Cascades National Park

My wife and I really enjoy the Diablo Lake Boat Tour. Note that reservations are required.

WA 20 goes through the North Cascades Natl. park.
There is quite a distance between points that would not justofy to me to set up at one location.
I would suggest staying a day or two around Rockport, Marblemount or Newhalem. There is a nice county park at Rockport right along the Skagit River. There is a Forest service campground near Newhalem. Marblemount as a couple small commercial parks. Nice park at Colinial Creek on Diablo Lake.
I would then move over by Mazama. There is several nation forest campgrounds along the way.
Next stop would be at Winthrop. Small town with western theme. Several commercial campgrounds in area and Perrygan State Park.
It is just to big to day trip from each end.

If you have done your home work you will already know about this web site.

The Park

The national park is a huge plot of land set mostly on its side, and has few access roads. Most of the accesses are off highway #20 as horse and back pac trails.

The east side is bounded by the State forests full of DNR camp sites.

Newhalem Wa is the one place that has an interpretation site just west of town, and the goodall camp ground is about 2 miles west from there. it is mostly for smaller rigs and is right on the river.

Next town west is Marblemount with a couple private campgrounds and services. There isn't much from there to Rockport where you'll find Steelhead RV park, and the day use area of Rockport State park. and the 530 highway to Arlington and I-5 to Seattle

Concrete is a small town west of Rockport, that is the entry to the Baker lake recreational area. that is also called the Mount Baker National forest. lots of bike and hiking trails.

highway intersects with I-5 at Burlington where we have all the big box stores and any service you need such as Freight liner M/H services. Camping World. and great restaurants.

To get to the only camp grounds with in the Cascades National Park you must go into Canada to the town of Hope and return to the US on 40 miles of improved gravel road.
That gets you to Lake Ross at the north end. where the US side of the border has several large M/H type camping spots.

There are many RV Parks/campgrounds in the area. Private, NFS, and state parks are available. We like to stay in Twisp at Rivers Edge. It is a little further "out" but we like to explore the Methow Valley. Winthrop can get a little crowded during peak season. If possible you should cross Hwy. 20. Baker Lake is really nice and the view will take your breath away.
