The morning starts before the town wakes: a long, low sky above the pier, coffee steaming in paper cups as the guides check fins and life jackets. Boats cut a slow ribbon across shallow turquoise; the sea is a bright, living thing that seems to breathe. Within an hour you're offshore, the island straggling behind like an afterthought, and then the radio crackles: whalesharks sighted. The boat slows to a hush and the water changes from mirror to infinite pattern — the pale spots of the world's largest fish drifting like slow, living constellations.

Bring reef‑safe sunscreen
Use SPF that’s mineral-based to protect coral and reduce chemical runoff; apply before boarding to avoid touching your face in the water.
Wear a snug mask
A properly fitting mask reduces fog and lets you relax in the water; rentals are provided but personal gear is often more comfortable.
Take seasickness medicine early
If you’re prone to motion sickness, take medication at least an hour before departure — the ride to whale shark grounds can be choppy.
Follow the guide’s distance rules
Only two swimmers enter per guide and each person can do a maximum of two rounds to limit disturbance to the animals.
