Two young boys are playing on a beach, crouched down and interacting with the dark sand. They appear to be building something, perhaps a sandcastle. The water's edge is near them, with small waves lapping the shore. In the background, several boats are visible on the water, which extends to the horizon under a cloudy sky. The beach itself has some seaweed or debris scattered on it.
