What Does a Freediving Trip to Koh Samui Cost? The Full Budget

A one-week freediving trip to Koh Samui costs most people somewhere between 25,000 and 55,000 THB per person (roughly £550–£1,250 / $700–$1,550 / €650–€1,450), all in. That covers your return flights to the island, a 3-day beginner course, six or seven nights of accommodation, food, and getting around. The single biggest variable is not the diving — the course price is fixed — it is how you fly in and where you sleep. Below is the honest, line-by-line breakdown so you can build your own number instead of guessing.

I get asked about total trip cost almost as often as I get asked about the course itself, and I understand why. The course price is easy to find. What people actually want to know is the real number that lands on their card by the end of the week. So let me lay it out the way I would if you messaged me on WhatsApp.

The course: 7,500–12,000 THB (the fixed part)

This is the one line you can pin down exactly, because our prices are published and include equipment rental and certification:

• Discovery Freediving — 7,500 THB/person (2 days). The taste-test if you are not sure freediving is for you.
• Beginner Course, Level 1 — 9,500 THB/person (3 days). The one most travellers come for: zero experience to certified, confident open-water dives.
• Advanced Course, Level 2 — 12,000 THB/person (3 days). For divers who already have a Level 1 and want to go deeper.
• Guided fun dives — 4,500 THB/person if you are already certified and just want to dive.

Everything in that list includes your gear and your certification card. There is no hidden "equipment fee" or "certification fee" added at the end — a trick that is sadly common in dive tourism. For the rest of this article I will use the 9,500 THB beginner course as the anchor, since that is what most first-time visitors book.

Flights: 4,000–40,000 THB (the biggest swing)

This is where budgets diverge most, because it depends entirely on where you are flying from.

Getting to the island

Koh Samui has its own airport with direct flights from Bangkok (about one hour, Bangkok Airways operates several daily). A Bangkok–Samui return runs roughly 4,000–9,000 THB depending on season and how early you book. If you fly the cheaper budget route — into Surat Thani on the mainland, then a bus-and-ferry transfer — you can cut that to around 2,500–4,000 THB return, at the cost of a few extra hours each way.

Your international leg to Bangkok is the wildcard. From Europe expect roughly 20,000–40,000 THB return; from within Asia or Australia, often 8,000–18,000 THB. I cannot control that number, but it is worth saying: Koh Samui's airport is a genuine money-saver compared with Koh Tao, which has no airport and requires a ferry of two to six hours. With us you fly in and you are at your hotel 30 minutes later — no lost day on a boat. (More on that in the honest Koh Samui vs Koh Tao comparison.)

Accommodation: 4,000–35,000 THB for the week

Koh Samui has the full range, and the island is small enough that nowhere is more than 30 minutes from the dive centre. For a week (6–7 nights):

• Budget (guesthouses, hostels, simple fan or AC rooms): 500–800 THB/night → ~4,000–5,500 THB for the week.
• Mid-range (comfortable AC hotel or pool resort, the sweet spot most students choose): 1,500–3,000 THB/night → ~10,000–20,000 THB.
• Comfortable (4–5 star beachfront resorts): 5,000 THB/night and up → 35,000 THB+.

Most travellers stay around Chaweng, Lamai or Bophut. Prices climb noticeably in peak season (December–February), so booking early matters more for your wallet than for your diving.

Food, transport and the rest: 5,000–12,000 THB

Day-to-day living in Koh Samui is affordable. A meal at a local Thai restaurant is 80–150 THB; a sit-down dinner at a tourist spot 300–600 THB. Budget on food is easily 400–600 THB/day; eat at nicer places and it is 800–1,500 THB/day. Over a week, call it 5,000–10,000 THB for food.

For getting around, a scooter rental is about 200–300 THB/day, or use the island's songthaews and Grab taxis. Add a small buffer for a SIM card, a massage or two, and the odd boat trip. Realistically 2,000–4,000 THB covers transport and incidentals for the week.

Three sample budgets for a one-week trip

Putting it together for one person on a 7-day trip built around the 3-day beginner course (flights from within Asia assumed; add your own long-haul leg if flying from further):

These are honest planning numbers, not a quote — exchange rates drift and your long-haul flight will move the total. But they are the right shape: a lean trip lands near 24,000 THB, a comfortable one with nice rooms and short flights closer to 45,000, and a properly indulgent week well past that.

How to spend less without cutting the diving

• Travel March–June. You get the year's best visibility and whale-shark season at shoulder-season prices, because it falls between the two main tourist waves. See the best time of year guide.
• Book flights early. Bangkok–Samui fares swing the most; a few weeks' notice can halve them.
• Stay mid-range, not budget. The jump from a 600 THB room to a 1,800 THB pool resort is small against the trip total and makes the rest-and-recover side of a diving week far better.
• Combine the course with a real holiday rather than flying in just for three days — the flight cost is the same whether you stay 3 nights or 10, so a longer trip is better value per day. The 5-day Koh Samui itinerary shows how to build the week around the course.

What is not in the budget (and does not need to be)

You do not need to buy any equipment. A beginner course includes mask, fins, wetsuit and everything else — and I would actively talk you out of buying gear before you have done a course, because you will buy better once you know what you actually like. You do not need dive insurance for a recreational course, though a general travel-insurance policy that covers watersports is always sensible. And there is no deposit required to hold course dates with us — you reserve on WhatsApp and pay when you arrive.

Ready to put a real number on it?

The honest summary: budget around 25,000 THB for a lean week and 45,000 for a comfortable one, with your long-haul flight added on top. The diving itself is the cheap, fixed part — and the part you will remember.
