Kona Ocean Guide
Kona and the west side of Big Island has an abundance of beautiful beaches and amazing ocean swimming. The water is warm, the coastline is dramatic, and most “best day ever” stories here involve a mask and snorkel, fins, and salty hair.

1. Manta Ray Night Snorkel
This is one of those experiences that people talk about for years.
What it feels like
Slipping into the ocean at night feels like entering another world. The water is calm and quiet as darkness wraps around everything. You float on the surface, breathing steadily through your snorkel, held gently by the slow rise and fall of the sea. Below, soft lights glow like moons underwater, illuminating clouds of plankton drifting in the dark.
Then they arrive. Manta rays glide in with an effortless grace that almost doesn’t seem real. Their wingspan feels enormous up close, yet their movement is slow, fluid, and calm. They loop and spiral beneath you, sometimes passing so near you can sense the shift of water as they move. There’s no fear, just awe and a feeling of being very small and very welcome in something vast and alive.
What to bring

Towel and a warm layers for after

2. Best Snorkel Spots
Snorkeling here is all about conditions. These areas come up for a reason. Pick based on what the ocean is doing that day and the kind of entry you want.
A popular snorkel beach with reef life close to shore and facilities on site. It can be a very easy way to get time in the water.
Hawaiʻi County Parks – Kahaluʻu Beach Park
Two Step is well known for clear water and strong snorkeling when it’s calm. Entry is over lava rock, so it’s the kind of spot that feels great when conditions are mellow and not worth forcing when they’re not.

Kealakekua is one of the most memorable bays on the island. The water often reads deeper and cleaner, and the cliffs give the whole place a dramatic scale. Many people experience it by kayak or boat, and it’s worth scanning the park info before you go.

3. Diving
If scuba is on your list, the “right fit” usually comes down to your comfort level, the style of trip you want (boat vs. shore, day vs. night), and how much guidance you prefer. Kona Honu’s trip page lays out the main categories without overcomplicating it.
4. SUP / Kayaking at Kealakekua Bay
Paddling is one of the best ways to experience the coastline when conditions are calm. Kona Boys is a long-running local outfitter focused on Kealakekua-area paddling, with rentals and tours.
