Fall Travel to Northwest in Fall.

For Mr. Rainier, Google Randle, WA and Packwood, WA for campgrounds. We stay in Maple Grove RV Park in Randle. It is a KM Resort park - not sure of their policy if you are not a member. Might be worth a call.

Campgrounds in Packwood and Randle are strategically situated in the middle of Mt. Rainier, Mt. St. Helens, and Mt. Adams. Can easily spend a week exploring there.

It is Olympic NP NOT "Olympia" NP. Olympia is the state capital.

Pacific Beach State Park in Washington is one of our favorites.

Any state park on the Oregon coast is great. Harris Beach is our favorite in SW Oregon.

Safe travels

Olympia Nat'l Park - definitely stay in Port Townsend which is a terrific little town with lots to do in the area. Fort Worden state park is great - right on the water.

You can easily do day trips to Hurricane Ridge - Olympia NP, or take the ferry out of Port Angeles for a day at Victoria, Vancouver Island. Pick up the city bus to take you to Buchart Gardens and back to the ferry landing for nice restaurants.

From Port Townsend drive a short distance south to Bainbridge Island and pick up a fast ferry to Seattle's waterfront. It docks at the Aquarium. Then pick up the monorail to take you to the Olympic Space Needle. Then back to Pikes Market for lunch and shopping and walk down to the ferry for your return.

Pick three state park along the Oregon coast for the best experience on seeing the whole coast. At Astoria on the north end is Fort Stevens State Park, mid-coast is Carl Washburne by the famous Heceta Head Lighthouse (we gave tours there :) ); and at the southern part Cape Blanco at Port Orford has huge lovely sites and a quiet beach to walk and another lighthouse to tour. We've also stayed at Beverly Beach, Bullards Beach and Harris Beach. All are state parks.

Washburne and Cape Blanco don't take reservations but we've never had a problem getting in, especially if you plan it for in the morning when folks are leaving.

Have fun planning your trip!

How late in the fall? Remember when in the mountains in the fall you can encounter freezing temps and/or snow.
In the valley, along the I5 corodore you can expect cool and rain.
The coast, best time of year to visit is mid Septenber to mid October. But again expect cool and rain.
The coast is best visited traveling north to south. Any of the Oregon state parks, plus private parks like Netarts Bay, Salmon Harbor at Winchester Bay are two of the best for views.
