A good friend of mine and I will be taking Coast Starlight down to Portland from Seattle in early May. The whole reason we are going to Portland is to see Multnomah Falls and Ramona Falls. Is there any kind of transportation that will take us from Portland to Multnomah and Ramona Falls? We are 20, just under the right age to rent a car for the day, and we do not really want to rent a cab to take us there because it would be outrageously expensive! Are there any low-cost alternatives at all?
