About this experience
Divers must have a certification for this trip. Divers without certification must book Discover Scuba Diving Koh Tao is an island just north of Koh Samui and is an excellent choice for the variety of dive sites there. From shallow, rocky sites to huge pinnacles, and a wide array of hard and soft corals, not to mention an abundance of marine life, there really is something for everyone. Your day will start with us picking you up at your hotel approximately 7:00 am. We will take you to the pier where you can enjoy some light breakfast and coffee/tea and meet Discovery Divers Team. The boat will leave the pier at 8:00 am. It takes approximately 80 minutes to reach Koh Tao by speedboat. Upon completion of the second dive the boat will return to Koh Samui, and you will be back at your resort around 3:30 pm.

Koh Tao is an excellent choice for beginners and experienced divers alike. There are about 12 different dive sites that we generally visit and which dive sites we do on a particular day will depend on the prevailing weather and dive conditions. Among dive sites available are Chumphon Pinnacle, Mango Bay, Shark Island, Twin Rocks, Japanese Gardens, as well as others. Generally we depart from our pier about 8:50 and return to the pier about 16:00. This tour is available for certified divers, and snorkelers also. All trips are taken our own Discovery Divers speedboats and include all equipment.

Amazing diving experience in Koh Toa from Koh Samui
Very professional organisation, with safety first, good supervising and instruction, nice diving spots and explanations about what to see, underwater life. Very good diving instructor, good food on the boat, transfer from the hotel etc. Everything organized online directly with Discovery Dive Centre.

Diving apparently good, but beware hidden extra charges. Disappointing purchasing experience.
My daughter throughly enjoyed her diving trip, seeing moray eels, groupers, barracuda and felt safe. And a good lunch. My significant gripe was the disappointing way that the trip was booked. On the website, I was able to select which hotel we were staying at (apparently within their complimentary pick up zone) - it was clearly on the drop down list. I then paid a significant deposit for the trip. Some significant time later, after money changed hands, a message appeared advising me that there would be an additional 1500 Baht for transport to/ from the hotel. They did not back down when challenged. This naturally goes against all sorts of trade descriptions / consumer rights / laws. The outfit apologised for “confusion”, but the only confusion is the way that they seem unaware that they are duping people. We ended up funding taxis to within the revised pick up zone. Suggest be very careful booking… An alternative company, which we have had a very positive experience with, is 100 Degrees East.

Very good always again!
General a good organisation of the trip. Staffs and necessary equipment in a really good condition nothing to complain!
Response from the operator: Thank you for the review. We pride ourselves on making sure we have top-of-the-range equipment and our highly experienced staff. We hope to see you back again.

First Class Company to dive with!
I went on another couple of dives with Discovery Divers and had another great experience. They have the best equipment, great dive guides (Filip, Pierre and Nai) and you will have a great day and experience with them. Fantastic communication with timely hotel pick up, pre dive orientation and post dive review to keep your dive log book up to date. They take you to great dive sites. I will be back diving with them in December!
Response from the operator: Thank you so much Garrett. We are so happy you enjoyed your first true "fun dives" after doing your Open Water Course and we are thrilled you got to experience the best our team and dive sites have to offer. Our staff has been doing this for a long time, and it goes to show that it doesn't matter who you are buddied with, you will have a great day regardless. SEA you in December!

What's not to like
My son and I had truly great time with Tom, our Thai guide, who is a superb diver. The Discovery operation is relaxed and really friendly, yet truly professional. Highly recommended. A fast boat and good lunch. What's not to like.
Response from the operator: Thank you for the great review, Charles. After 26 years, we have perfected the ultimate blend of fun, friendly, safe, and organised. We appreciate you highlighting these points and recognising this too. We can't wait to see you both back again!

Why this scores 72
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Koh Tao 2-Dive Day Trip from Koh Samui for certified divers: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Koh Samui.
How much does Koh Tao 2-Dive Day Trip from Koh Samui for certified divers cost?
+
Prices start at $5750 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Koh Samui usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Koh Tao 2-Dive Day Trip from Koh Samui for certified divers take?
+
Plan for about 8 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Koh Samui is not rushed.
Is Koh Tao 2-Dive Day Trip from Koh Samui for certified divers worth it?
+
It holds an Outty Ranking of 72 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.9/5 across 91 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Koh Samui, and how flexible the cancellation terms are.
Can I cancel or reschedule Koh Tao 2-Dive Day Trip from Koh Samui for certified divers?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Koh Tao 2-Dive Day Trip from Koh Samui for certified divers suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 8-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Koh Tao 2-Dive Day Trip from Koh Samui for certified divers?
+
Around 32 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Koh Samui can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Koh Samui and add a light layer if any part of the 8-hour experience runs outdoors or after sunset.
Where does Koh Tao 2-Dive Day Trip from Koh Samui for certified divers start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Koh Samui within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Koh Samui?
+
On Outty we rank every Koh Samui experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Angthong National Marine Park VIP Small Group Tour, Cooking Class in Koh Samui with Micro Organic Garden, Half Day Elephant Home Sanctuary in Samui. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Koh Samui?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Koh Samui?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
