The Big Island Manta Ray Night Snorkel is one of Hawaii’s most unique wildlife encounters. You float near the surface while manta rays glide below, feeding on plankton attracted by underwater lights. The setting is calm, bright, and unforgettable – perfect for beginners and confident swimmers alike.
Only a few places in the world offer manta viewing this close, and Kona is the most reliable. The rays move like slow, sweeping wings beneath you, sometimes just inches away. Because you stay on top of the water the whole time, the experience feels easy and peaceful rather than intense.
How the Tour Works
Most trips begin at Honokōhau Harbor. You check in, get fitted with gear, and ride a boat to a manta viewing zone. After a short briefing, you enter the ocean holding onto a light board that floats at the surface. The lights attract plankton, and manta rays soon arrive to feed.
The in-water portion usually lasts 30–45 minutes, and wetsuit tops help keep you warm. Guides remain close to assist and share helpful manta facts.
What You’ll See
Manta rays often have 10–12 foot wingspans and move with smooth, gentle motions. They loop and glide through the glow below you, creating a scene that feels dreamlike and quiet. Many guests describe it as peaceful, slow, and surprisingly emotional.
