Where the turtles live.
Turtleneck is exactly what it sounds like — a shallow reef where green turtles have established a quiet residency. The reef is healthy hard coral over 5–20 metres, with patches of seagrass at the deeper end which the turtles graze through the day.
On a typical dive you'll see 3–5 turtles — usually green turtles, occasionally hawksbills. They're habituated to divers and tolerate close approach if you stay slow and respectful. Beyond the turtles: hard coral garden, butterflyfish, parrotfish, the occasional reef shark passing in the deeper sand.
"If you've come to Bali to see turtles, this is the dive."
Open Water-friendly. Best paired with Blue Lagoon (5 minutes' boat away) for a turtle-and-macro morning. Currents are gentle, viz is reliable, conditions are forgiving.
