Black Stone is an advanced left-hand reef break in the Nusa Dua chain, named for the dark reef visible at low tide.
A wedgy, powerful left with a critical takeoff zone. On bigger swells, the wave produces thick barrels. The takeoff is steep and demands commitment.
Wet season (October-March) with solid SE swells at 4-8ft. Best at mid tide. Needs size to really turn on.
Paddle from the Nusa Dua beach or short boat ride.
