Great overnight stop driving the cascade loop. I arrived in time to go into the city offices, they were helpful and friendly. There seems to be two locations: one is to just park along the street next to the park, where there are restrooms. (Great bakery/restaurant) I parked further down with picnic tables right by the river. At this location there's free showers and a restroom which look clean. There are two locations with envelopes to pay next to both restrooms. It's an open area with different businesses, there was one tenter and two vehicles dry camping.
