Snoqualmie Falls is one of the easiest and most family-friendly stops you can make near Seattle. The main viewpoint is just a short walk from the parking lot, and there's also a trail down to a lower observation area if you want to get a little closer. It can definitely get a bit crowded, especially on weekends, but it's easy to see why. The falls are beautiful year-round, and despite the number of visitors, it still feels like a worthwhile stop to take in one of Washington's most iconic waterfalls.
