Despite the absence of the higher quality diving sites found on the northern side of Koh Tao, Koh Samui does have some unspoilt diving sites to explore.

Trips are made to the Ang Thong Marine National Park, to the Southern islands of Samui or to Koh Tao.

Accommodation facilities range between budget beach bungalows and 5 star resorts.

Hi, can you give me the price for the PADI open water course? Thank you!


James July 22, 2017


Can you let me know where you are going diving on Thursday, Friday & Saturday next week.

I land in to Koh Samui at 7:30am is it possible to go be picked up from the airport and go diving then? I realise some boats leave at 8am, wasn’t sure if there are any other boats going out or if there are shore dives or closer dives you can do?



Mark August 01, 2017


Do you have the equipment for the Diver Propulsion Vehicle (DPV) Speciality course for 2 people this week.
We are both advanced open water divers and above 12 years.

Many Thanks

Hi there,

We are looking at either 2 or 3 dives and wondering what is the package price for the best dive site? On either Saturday or Sunday.

Below are a list of enquiries that we have:

1) One of us will need a general refresher’s course. Wondering how long would this take and do we take the refreshers course on the dive day itself or the previous day?

2) How big would the dive group be?

3) If we would like to put in 2-3 dives and including the Sail rock, would the dive sites be calm, simple safe ones?

Thanks, May

Hi, My wife and I are heading to Koh Samui in late November and are looking to get our PADI open-water qualification (we may also have a friend joining us, so potentially a group of 3).

I wanted to inquire on the price for this course and understand if I could do the course on non-consecutive days?

I have also read, it can be possible to complete the eLearn and pool qualifications remotely, is it an option to complete this in Melbourne Australia prior to arriving in Koh Samui?

My husband would like to do a dive master course over the Christmas / New Year period. He has completed the PADI rescue course and EFR (still within its 24 month validity). He is an experienced diver (over 100 dives). He does not want to become a dive instructor but would like to complete the dive master course in any case. Is it possible to do it in 2 weeks (late Daecember / early Januray?
Kind regards,
Deirdre and Sebastien


Sebastien October 14, 2017

My husband is interested in doing a divemaster course. Could you please give me some information (price? duration? etc…) He has already completed the Padi rescue diver and EFR. He doesn’t want to make a career as a dive instructor, just for him personally.

Hi, I’m looking for the prices for your beginner courses.


JOHN October 26, 2017

My wife Ally and I are travel agents specializing in scuba related travel, mostly to Mexico, the Caribbean, and Hawaii. We are traveling to SE Asia in January to check out the diving. We are interested in two days of diving in Phuket, 16 & 17 January. Our party will consist of three divers. We are also looking for a suitable place to stay for four nights (15 Jan – 19 Jan) if you have any recommendations, we would appreciate it. Please let me know the best price

Best regards,
John Hicks

Dear Sir or Madam,

we’re two girls from Germany (1 Diver, 1 Non-Diver) who would like to book a half day trip with 2 or 3 dives.

I have 19 logged dives (last one on 30 October at Koh Phi Phi) and my friend tried Scuba diving in Mallorca and did another two dives in Mexico in June but has no certificate. Is there a possibility to go diving together and if yes, how much would that cost for each of us including all equipment and fees?

Furthermore, we are really interested in a diving trip to Khanom (pink dolphins). Do you sometimes go there?

We just arrived at Koh Samui and stay at Banburee Resort & Spa only until 4th of November. Do you have some tours today or tomorrow?

Thanks in advance for your help.

Best regards,
Linda and Aileen

How much for the PADI Open Water diving course?


Ken December 05, 2017

Interested in both a Beach dive and a 2 tank boat dive in late March, 2018, for me and my 14 year old son. We are both PADI OW certified, but very much at the beginner level.

1) What boat dive do you recommend for beginner level divers?
