I've been to Multnomah Falls twice and wouldn't mind going back. It's very beautiful. I haven't tried any hiking there, but would like to. This is a good place to bring visitors and you can even take them along the Columbia River Gorge senic highway. There is a on site gift store and restaurant, but the restaurant doesn't have many vegetarian/vegan items;-(
Pros: it's free!, the beauty
Cons: crowded in summer
