Simply known as "The Big Rock," this massive boulder on the northwestern shore of Lake Cushman is one of Washington's best cliff jumping spots. With a maximum drop of approximately 17 feet, the height of the drop isn't necessarily intimidating, which makes this spot accessible to nearly everyone. That being said, The Big Rock is notorious for drawing a rather large crowd because of the approachable jump and the easy access from N Lake Cushman Road/NF-24. Get there before lunch on a weekday, however, and you'll likely have the rock to yourself.
Want to avoid the crowds of the The Big Rock? Head east 0.7 miles to the North Shore West swimming beach or an additional 0.9 miles to North Shore East swimming beach and your odds of having more a more tranquil lakeside experience are pretty good.
Swimming holes and cliff jumping can be extremely dangerous and unpredictable outdoor activities that pose significant risks regarding personal safety. Changing water levels, unseen rocks, and river bottoms that have shifted with currents and seasonal weather can turn a well-known jumping area into a serious hazard. Prior to engaging in these activities, extensively scout the current conditions, and understand the risks involved with serious injury and the logistical challenges of evacuation from the water so you can make safe decisions.
