The gift shop sells coffee and pastries on the left side and gifts on the right side. We walked down to the lowest viewing area without going to the trail to go to the very bottom of the falls.
The top level is accessible, and after that, you need to go down some stairs. There are several viewing level areas with great views. Coming down from the walkway has stairs but I also saw hills, so perhaps it is accessible. There is a covered walkway over the road to reach the waterfall side. Across the street is a free and bigger lot. It has the gift shop and bathroom and a small parking lot that costs $7 for up to 2 hours, then $5 an hour. When you enter, left is Salish Lodge and Spa, so turn right to the go to the small paid parking lot.
Informative signs such as below give the history. Beautiful 270-foot waterfalls and the first hydroelectric power plant in the Pacific Northwest.
