There is a lot to do in Washington. We have three National Parks: Mt Rainier, Olympic, and North Cascades. Olympic has many easy trails in the rainforest and on the wilderness coast that are beautiful, accessible in June, and mostly flat. In addition to the natural parks, there is a huge amount of wilderness protected land and national forest that have gorgeous features. There is whale watching as well in the Salish Sea. Washington is home to many exceptional viticultural regions if you're into wine. Seattle itself has a great variety of museums, restaurants, and markets. Eastern Washington has beautiful state parks, dry rivers, scablands, recreational lakes, and more. It really depends on what you like doing.
