Posted on Google AndreasTrustindex verifies that the original source of the review is Google. Total sympathische Mitarbeiter der Tauchschule. Nui hat einen schönen Refresher mit mir gemacht und Isa und Marie sind ebenfalls sehr interessante und total liebe Menschen, die deutsch sprechen und Ausbildung sowie Guiding machen. Der Trip zum Sailrock morgens war zwar verdammt früh (6 Uhr ging es aufs Boot), dafür waren wir die ersten am Spot und es gab auch ein leckeres und reichhaltiges Frühstück.Posted on Google Natthaporn JiratarachotiwatTrustindex verifies that the original source of the review is Google.

Bei Big Bubble habe ich meinen Open Water und advanced Open Water Kurs gemacht. Vielen, herzlichen Dank an Isa, meiner Tauchlehrerin. Du hast mir den Tauchsport sehr professionell und sicher beigebracht. Vielen Dank auch an die Big Bubble Crew vom Büro - sehr professionell und auf die Kunden orientiert. Dyan, Moss, Aten and Air - Danke für Die coolen Fundives. Und Poy - Deine positiven Vibes und Dein pinker Octopus bleiben mir immer in Erinnerung. Das Glück war auf meiner Seite. Ich habe zweimal einen Walhai gesehen. Auch sonst ist es auf Koh Tao wunderbar zum Tauchen. Sehr viele unterschiedliche Tauchplätze. Vom Wrack bis zu schönen Riffen und unglaublich eindrücklichen riesigen Fischschwärmen. Mich hat das Tauchen gepackt und ich komme bald wieder zurück auf diese schöne Insel. Lieben Dank an Tisha. Bei unserem allerersten, gemeinsamen Tauchgang haben wir tatsächlich einen Walhai gesehen...Was für ein Zeichen... Danke, dass Du mich zum Tauchen inspiriert hast. Es hat sich eine neue Welt für mich aufgetan. Gut Luft, allen die diese Rezension lesen - kommt nach Koh Tao, es ist fabelhaft......Posted on Google MadiTrustindex verifies that the original source of the review is Google. Me and my friend had a great experience with big bubble! I did the try dive for 1 day and felt very supported and had a lot of fun too :) Dyan was a super good instructor 👌

PADI Open Water, Kho Tao – Our Open Water Dive instructor, Dyan, was so friendly and patient with us novices. Small class meant we got lots of attention. I was also impressed with the diving school… read more for other reasons. Firstly, it is one of the only Thai owned and run dive school and has been established for 30 years. Secondly, their beach access and bar with basic bubble bungalow accommodation across the road made the whole experience more enjoyable.

Best Diving School – Best diving instructor – This was such a great experience, I had the best time with the best instructor, ICE, who made me feel very comfortable and safe. Everything was done in a very… read more safe way. Everything about the dive was reviewed first by my partner instructor ICE. It is a smaller diving school in a small town and this means that there are far fewer people who sign up than in the big cities. This makes it a cozy relaxed atmosphere with plenty of space on the boat. My biggest recommendation to the diving school, instructor ICE, as well as his colleagues. I will definitely return.
