16-24. So if it was me. Depending on what time you fly into SeaTac. I would head straight to Leavenworth. Spend the next day in and around the town. You won’t miss a ton of sights on 2 of the drive is at night. After Leavenworth I would head over to Winthrop. Drive between the two is a ton of orchards. Apples and cherries mostly. I would try to book a room at riverside edge in Winthrop. Everything is walking distance in town. There are some cool hikes outside of town if you go up the methow. Falls creek sticks out as an easy hike with good views. Hit school house brewery for best food in town with good beer. Avoid Mexican restaurant and cider house for food. I would then pop over 20, stop at any of the areas for a great hike on the way over. I would then kick north to either glacier or maple falls. Stay up at a cabin or one of the ski bum hotels up there. That should put you about mid afternoon on the 19th if my math is mathing. Depending on how tired you are from hiking and sitting in a car I would either go up to baker that day or the next. Artist point is about the coolest hike I have ever been on. I usually do it atleast once a year. But it is a long hike. That would get you to the 21st. I would then head west to anacortes or oak harbor, If you want to check out some cool island towns anacortes, ferry out to the little island towns. If you want to check out Olympics I would go oak harbor and then ferry over to port Townsend. Once on the peninsula my knowledge is somewhat shaky. I have been up through hoh, but I don’t have any names or places. I do know if you are wanting to see cool landscape it’s tough to beat. Mostly old grown timber once you get off the main roads. That’s about all I got. If you need clarification on anything let me know and I’ll get you answers.
