Salt air and the slap of small waves set the rhythm as the fast boat cuts out from Sanur toward Nusa Lembongan and the larger, wind-battered cliffs of Nusa Penida. You step onto the deck with a snorkel vest in hand and the sea spread wide — the day is planned around three shallow coral sites with a priority stop at Manta Bay when conditions allow.
