If your sister lives on the peninsula and you're going camping, make sure you go to:
- Hoh River Valley (the only temperate rain forest in north america, although the best time of year to go is spring when it's POURING and the spanish moss is literally dripping and the moss bottomed streams run clear clear clear)
- Hurricane Ridge (on a clear day you can see to Vancouver Island)
- Hot springs (either Sol Duc or Olympic)
- Port Townsend (historic Victorian town)
- Port Gamble (historic company mill town...the working class version of Port Townsend)
- Poulsbo (settled by Swedes, lots of interesting shops on the main street by the marina)
- Sequim (if you're here in the August, some of the lavender fields shouldn't be harvested yet)
- Ocean beaches (Many people say Ruby Beach is there favorite)
I assume you'll be arriving in Seattle. You'll probably want to take one or two days. My places to take visitors (some already mentioned)
- Pike Place Market
- Pioneer Square
- Kerry Park (on south slope of Queen Anne...best view of the city skyline/harbor with Mt. Rainier in the background. This is the money shot!)
- Ballard Locks (aka Hiram A. Chittenden Locks)
- International District (specifically Chinese restaurants and Uwajimaya, a large Japanese market/department store)
- Public art in Fremont (Waiting for the InterUrban, Troll, Lenin, Rocket) as well as funky shopping and some good restaurants
- UW (because I happen to work there). Suzzallo Library Reading Room is the second most beautiful room in the state (after the state capitol rotunda) and the world's largest book is on display. Also the Burke museum has an excellent local history/culture collection incl. native american stuff
- Alki Beach (West Seattle) more view of the skyline and people watching along the promenade. good restaurants along the beach as well.
In addition, Victoria, BC is a 1 1/2 ferry ride from Port Angeles and if you're staying on the peninsula, it's very easy to include as a day trip or an overnight. Except for Butchart Gardens (which is the model for the gardens at the EPCOT Canada pavillion) all the main sights (Provincial Parliament, BC Museum, high tea at the Empress Hotel, shopping (Murchies tea and Roger's chocolate YUM!) are downtown around the Inner Harbor (where the ferry docks). Butchart Gardens is about a 1/2 hr north of downtown, but many many buses so very easy to get to without a car.
So there's a start. Do you have specific things you like to do on vacation (might give me a better sense of what to recommend). Let me know if you make it to the UW, I'd be happy to show you around.
