If you are going in the summer, take 20 thru the park and down into Mazama. Stop at the Mazama store and get the sea salt baguette…you won’t regret it. They also do coffee drinks and good iced chai. Continue on to Winthrop, have lunch/ dinner at the School House Brewery in Winthrop or the Highway 20 Pizza. Next town in Twisp, the Twisp Pub has a really good selection of beer form all over the area. Winthrop has the most places to sleep from a hostel to camping, Pine Near in Winthrop has teepees and Pearrygin Lake has rvs , but you need reservations for that. The swimming in Pearrygin Lake is really good too. There a really good coffee place in Twisp, the Blue Star…it’s just outside Twisp. Also, take my word for it, stop in Hank’s Grocery store in Twisp… it’s an experience…look up as you shop the aisles. Hanks has the best prices for food and gas of all the towns, so wait till you get there for gas, especially. You can take the back roads and see the Grand Coulee Dam. Taking that route will get you to Spokane. After Spokane is Cour d’Alene, big, big lake, kinda touristy but that lake is impressive. Get ready for crossing the Idaho panhandle. It’s a lot uphill and twisty/windy. Just as you come to the MT boarder is the 100,000 Silver Dollar Saloon. Go inside and see the silver dollars but don’t eat the food…truly horrible. You can go either the back roads way to Flathead Lake, there is a hot springs that way or you can take the highway to Missoula and go north from there to Flathead and Glacier. I prefer the back roads to Flathead. Have a great time…it’s a special part of the world.
