Kenneth the guide and Max the boat man, we’re courteous friendly and knew what they were doing. Kenneth had everything organised and was great when we got in the water. Just an FYI for slightly older ladies who struggle to get back into the boat if the steps are too high out the water for you to step/climb on to: get them all the stand on the side of the deck so it leans deeper into the water and thus the steps are deep enough for you to access with ease!! All in all a great day out!

The guide was very punctual, arrived our hotel 20 mins before 8am which was very impressive as some guides/agencies don't keep time that well. He was also friendly and helpful, taking many photos of our family. The tour included drinks but not food. The tour time (around 4-5 hours) was perfect for our family especially for my old parents, who can't do longer boat trips. Overall it was the best value compared to price. Thank you!

Alles in allem ein wirklich sehr schöner Ausflug. Besonders gut finde ich, dass man nur als kleine private Gruppe den Ausflug machen kann. Wir wurden direkt an unserem Hotel (ganz im Norden) von einem kleinen Bus abgeholt und an den kleinen Hafen an der Thong Krut Pier im Süden der Insel gebracht. Von dort aus ging es dann direkt auf ein Long Tail Boot. Nach circa 15-20 Minuten Fahrt erreicht man die Insel Koh Madsum. Die Insel hat einen traumhaften Strand und eignet sich besonders für Postkarten ähnliche Fotos. Es gibt dort eine Bar an der man Getränke und Kleinigkeiten zum Essen kaufen kann. Man kann super auf der Insel schwimmen gehen und entspannen. Bei der zweiten Insel konnte man auch noch mal sehr gut schwimmen und vor allen Dingen über einem Riff schnorcheln. Unser Guide war absolut nett. Soft Drinks waren auf dem Boot kostenfrei. Zusätzlich bekamen wir kostenlos die Schnorchel Ausrüstung (mit ganz neuen Mundstücken!) zur Verfügung gestellt. Fazit: Spaß für die ganze Familie!
