#9 South to #20

#108 West for a short bit, then back on #101
#101 North etc......
Highway only route from New West is 1000kms round trip total. Add to this any backroads which you must do, and it is definatley an overnight trip. An early departure (ie: 6:30am or 7:00am) and you could actually do the whole thing in one day, but you'd have to cruise at 140-160 all the time.
#101 South along the Hood Canal is scenic, curvy, and full of cars/RV's, so plan on practicing your blitz passing skills. No point in going further South of Shelton unless you intend on exploring B roads South of Olympia and Aberdeen on the coast. The entire west side of the peninsula is a waste of time. All the trees are gone in the Quinault Indian Reservation and you only get a brief peek at the coast line. Best to stay up North, or go further South.
Nothern section (between Forks and Port Angeles) is beautiful, with fewer cars, nice pavement, and a very scenic section along Lake Crescent with about 100 25-25mph turns in a row. Surface is groovy so you can't really push it. No matter, it's usualy busy with cars so just sit back and enjoy the view.
If you are up this way, you must take in the B roads #113, #112 to Neah Bay and Ozette. New riders should be very cautious here as there are many blind and decreasing radiuss turns. Even at slow speeds it's a great road.
Skip the west side and just go down and up the East side of the peninsula, or stay along the North side and go to Neah Bay. With an early start you could easily go to Neah Bay and back in one day.
Do not speed anywhere around Sequim (about 30 minutes West of Port Townsend) as it is a known hot spot with the locals. There is a small espresso hut in the middle of hot spot that wiill give you a free latte if you bring in your speeding ticket. Police frequently use helicopters.
