If you are driving to the coast from Portland on HWY 6 with an eventual destination at one of the cities North of Tillamook or just venturing down to coast for a tour of the Tillamook Chees Factory then the best way to travel is to take the Wilson River Loop road and cross the Wilson River and take a Left on Latimer Road which will allow you to avoid the town of Tillamook and save a few minutes on your trip. This is also the quickest way to get to the Cheese Factory as Latimer Road connects to 101 just South of the Cheese Factory and you will see it on your right hand side as you approach 101.
This is also the way to get to one of the busiest Wilson River boat launches right where the loop crosses the river to the right is a large parking lot and boat launch and pull out facility.
