Need a Great Vacation spot on West Coast…PLEASE HELP!!!!?

My girlfriend and I try to go on a vacation every year to a new spot. Two years ago she was pregnant we decided to go to the AZ. and did the train ride up to the Grand Canyon then drove to Hoover Dam and then followed to Vegas. Last year we had our little boy and decided to go to S.F. which was fun and easy with all the attractions. This year I’m stuck without any ideas. Would like to stay on West Coast, was looking at New Mexico, Oregon, Washington, and Colorado but have no idea what to do there. Any ideas would be greatly appreciated. “No ski resorts or theme parks the kid is too young for that”
