The Dalles area of Interstate Park is incredibly fascinating and it is easy to lose track of time as you explore the amazing rock formations. By visiting the website for the park, you can learn about the geologic history that goes back over a billion years and involves earthquakes, volcanoes and glaciers. Add to that, roaring water that grinds rocks against rocks and you have the Dalles, known for its potholes. It’s kind of like a giant rock playground. The part of the park hosts some excellent rock climbing, canoe rentals and is walking distance to the small downtown of Taylors Falls, where you will find shops, food and beverages of all kinds. If you are not a camper, there are other accommodations available in town and nearby.
