The World's Largest Waterfall
Dry Falls is located in Central Washington in the heart of the Grand Coulee. 3.5 miles wide and 400 feet tall, it dried out after the last Ice Age flood thousand of years ago, but it was once the largest waterfall known to have existed on earth. There's a great indoor exhibit at the Dry Falls Visitor Center right next door and plenty of outdoor activities in/around Dry Falls State Park. Make sure you have your Discover Pass for parking.
