swim-through
Diver's rock tunnel
A swim-through is an underwater passage or tunnel that divers can pass through, typically a natural formation in rock or coral: The reef has several swim-throughs popular with snorkelers.
In video games, particularly racing or flying sequences, a swim-through is a checkpoint ring or gate the player must navigate through to complete an objective.
