Cool things to see and do in Washington State. ?

Question

I am planning on driving across the State next week. Looking for things outside downtown Seattle.

Answer 1

Mt St Helens volcano center-SW of Seattle I-5 freeway toward Longview-Kelso(hope u have a car)--then over to Columbia River follow it to the Pacific Ocean,either way up or down the river is a nice drive. Maybe go up into the Olympic mt, range near Port Angeles--catch a ferry  into the The San Juans islands--Have fun!
