Review of Koh Tao’s First Light Snorkel Adventure: four bays, early waters, onboard Thai lunch, practical tips, and honest drawbacks.

“Les plus: guide expérimenté, connaît bien les lieux, tres gentil. Une personne avait le mal de mer et a reçu un traitement a bord rapidement. Le capitaine connaît également bien les lieux.

Sensation de picotement lorsquon est dans l'eau mais qui disparait lorsqu'on se rince a leau fraiche. Repas: riz blanc, poulet bouilli, 3 morceaux de légumes, aucune épice.
