The Wave

Type

Both (Don Don is primarily a right-hander)

Bottom

Coral reef (outside); sand (inside)

Shape

Punchy, hollow outside; slow and forgiving inside

Length

75–150m (outside)

Skill Level

  • Who it's for: Beginner (inside) / Intermediate–Advanced (outside Don Don)
  • Why: Outside reefs are over coral with significant power; inside is safe sandy-bottomed fun.

Hazards

  • Coral reef on the outer breaks
  • Boat crossing required to reach outer reefs (short but necessary)
  • Strong current on bigger swells outside

Local Tips

  • Hire a local boat from the village, a small fee gets you dropped at whichever outer reef is firing.
  • The inside wave is one of Lombok's best beginner options when Selong Belanak is blown out.
