The sun drops behind a black volcanic ridge and the ocean exhales cool air as the boat eases away from Kailua-Kona’s harbor. High-intensity LED lights cut into the dark water like beacons; within minutes, the surface becomes a stage. Manta rays — broad, winged silhouettes — circle and turn, funneling plankton into gaping mouths as you float, buoyed by a wetsuit and the hush of the Pacific.

Arrive Early for Check-In
Plan to arrive at least 30 minutes before departure to complete briefings, get fitted for a wetsuit, and stow belongings securely.
Motion Sickness Prep
If you’re prone to seasickness, take a preventative medication or use acupressure bands before boarding — the short ride can still be bumpy at dusk.
Respect the Animals
Keep a safe distance, avoid white lights or flash photography, and follow guide instructions — mantas feed on plankton and tolerate calm, non-intrusive observers.
Protect Your Camera
Use a secure wrist strap or chest mount for GoPros; the operator often provides photo packages but personal gear should be tethered in the water.
Snorkel Mask (if you prefer your own)
A well-fitting mask reduces fogging and increases comfort during a night swim.
Light Wetsuit or Rash Guard
Keeps you warm and buoyant during extended time in cooler evening water.
Reef-Safe Sunscreen
Apply before boarding to protect skin and the marine environment; no lotions in the water after briefing.

Anti-Seasickness Medication or Bands
Useful for those prone to motion sickness on the boat transfer and during surface intervals.
