This is not an alpine mountain road, the kind I typically reserve for a \"very good\" rating but I´m giving it 4 stars to get your attention. If your headed to the coast anywhere near Corvalis you need to forget about Hwy 20 and take Hwy 34, the Alsea Highway road. Hwy 20 is the route preferred by tourists, RVs and trucks. Forget about it. Take the Alsea Hwy and you will be raving too. The road surface is excellent as it undulates while taking numerous turns through thickly forested terrain. Several times you´ll find yourself in a tunnel of trees. There´s nobody out there ... because they are all on 20! And when you get to the coast stop in for some chowder or fresh Dungeness crab! Enjoy!
