The Arch is a boat-access site on the Grand Turk Wall featuring a combination of vertical wall, reef, and cave topography.

Divers encounter mild currents, though surge and stronger flows can occur, particularly near the cave entrance. Visibility ranges from 10 to 30 metres, and water temperatures remain between 26 and 30 degrees Celsius. Due to the cave structure and potential for surge, this site is suited for intermediate divers with solid buoyancy control. Night diving is available to explore the site after dark.
