We rode on I84 for the first 10 miles then we exited to the Historic Columbia River Highway. Cars were allowed on the road for the first few miles and then the road turned into a paved bike trail - no vehicles allowed. Today was a sightseeing day with beautiful waterfalls, views of the river, more amazing rain forest, and negotiated a long staircase manhandling the loaded tandem.
One of multiple beautiful falls.
