Scuba diving in the clear waters of Koh Tao

Dive Onda by LUM

Strategic partner

Recommended by LUM. We send every guest to Dive Onda. Ask us to arrange it and we'll sort the pick-up, introductions, and everything in between.

Why this collab

Ready to dive Koh Tao? We've got you covered with our strategic partners at Dive Onda. First breath underwater or levelling up your certification — it's high-vibe diving backed by top-tier coaching.

What we love most is how they handle group dynamics: dive solo with a personal coach, as a couple, or in a small group making new friends — they adapt to your vibe. Dedicated attention that makes diving effortless: flawless buoyancy, smooth technique, total confidence.

And with in-water HD video feedback, you review your dives on screen and watch your progress step by step. Relaxed, personal, super fun — top-notch coaching done your way.
