A typical day on this expedition includes up to 4 dives, including early morning or night dives timed with spawning events:
Light breakfast → briefing → Dive 1
Full breakfast → relaxation → briefing → Dive 2
Lunch → relaxation → briefing → Dive 3
Snack → relaxation → briefing → Dive 4 (sunrise, sunset, or night dive for spawning)

Dive sites are mostly in the Rock Islands Southern Lagoon (UNESCO World Heritage Site), with some dives at Peleliu. Skiffs transport groups to dive sites in 5–15 minutes.

Moorish Idol & Twin Spot Snapper Aggregations
This expedition focuses on two spectacular spawning events:
Moorish Idol aggregation: Over 1,000 Moorish idols gather for full moon spawning, attracting hunting reef predators.
Twin Spot Snapper spawning: Thousands of snapper rise from the deep at dawn, drawing bull sharks and oceanic blacktips in a dramatic underwater “firework display.”
