Très bons contacts directs avec l’agence pour organiser l’activité.
Et très bon prix 👌😊
Prise en charge à l’hôtel de qualité.
Très bonne surprise avec le beau buffet qui nous attendait à notre arrivée pour le petit-déjeuner 👏👌🤩
Ensuite briefing de la journée par notre excellent guide et son équipe.
Nous étions 25 dans le bateau.
Trajet de 110min jusqu’aux îles avec boissons (eau et pepsi). Et des fruits plus tard.
3 sorties de snorkeling de 30 minutes environ dans de très beaux sites regorgeant de très beaux poissons dont des poissons clown (“Nemo”).
Bon déjeuner sous forme de petit buffet pris sous les arbres sur l’île de Surin Nord.
Ensuite visite du village de Mokens sur l’île de Surin Sud.
Et enfin, retour en 110 minutes avec café glacé ou jus et une bonne petite pâtisserie.
Et en rentrant à la base, surprise: un buffet nous attendait à nouveau pour les plus affamés.
Précision: l’ordre des activités peut changer en fonction de la météo et du niveau d’eau.
