The first platform you hit doesn't have the best view but it gets better as you keep walking. Make sure you park across the street as that lot is free. It was only a half hour drive from our hotel in Bellevue. Speaking of time, it's crazy how close they are to the Seattle area given how quiet and the remote the area is. Personally I don't think they're a must do if you haven't been to Seattle before and are having trouble deciding what to prioritize, but they're definitely worth a stop if you have the time. These falls aren't very wide but they are very tall and quite a site. I've visited Seattle dozens of times over the years and we frequently travel on the I-90 on road trips so I'm quite amazed I'd never been here before.
