A 4 island tour Krabi private boat costs from about ฿4,050 for a small-group longtail charter and ฿8,900–฿10,995 for a private speedboat in 2026. You get the whole boat. Your own departure time, your own pace around Phra Nang Cave Beach, Chicken Island, Tup Island and Poda Island. Split four or five ways, a private longtail costs about what a shared seat does, minus the crowd.
Introduction to the 4 Island Tour
Overview of the 4 Island Tour
The 4 island tour Krabi private boat option is the classic island-hopping day with the strangers deleted. One captain, one boat, your lot and nobody else. Exclusivity's the obvious perk. The real one is time. Leave at 07:30 and Phra Nang Beach is nearly yours. Stay on the sandbar till the tide swallows it, or hang around on Poda for a sunset the shared boats never see.
The scenery's the same as on any 4 Island Tour: limestone sea stacks, green water, white sand. A private boat just lets you see it when it looks its best.
Islands Included in the Tour
- Tup Island — two islets and the Talay Waek sandbar. Private boats can time the stop exactly to low tide.
- Chicken Island — the chicken-head pinnacle and the best reef snorkeling on the route.
- Poda Island — long beach, shade, lunch spots and the sea stack.
- Phra Nang Cave — the Princess Cave shrine and the beach below the Railay cliffs.
Every one of these islands looks best at the edges of the day. At midday the light's flat and the beaches are busy. Early or late, you get colour and room to breathe. Stop-by-stop details are in the island guide.
Understanding the Private Boat Experience
Types of Boats Available
Private boat rental comes in four sizes, roughly:
| Boat | Group size | Price range (whole boat) | Best for |
|---|---|---|---|
| 4 Islands Private Longtail | Up to about 8 | From ~฿4,050 | Couples, families, small groups |
| Larger longtail or two boats | Up to about 20–28 | ~฿5,950–฿10,850 | Big groups, parties |
| Private speedboat | Up to about 20 | ฿8,900–฿10,995 | Comfort, rougher months, adding more stops |
| Catamaran or yacht | Varies | Quoted on request | Sunset cruises, celebrations |
For most people the 4 Islands Private Longtail is the sweet spot. It lands right on the beach, there's only the one engine making noise, and lots of charter boats throw cushions and a shade canopy on the bow deck. Go for a private speedboat if you want to tack on Hong Island or Railay West, or if it's rainy season.
Safety Measures and Regulations
Same rules as the shared boats. Krabi Tours operators and private boat rental outfits should give you a life jacket per passenger (ask for child sizes), a registered boat and a licensed captain. The registration number's painted on the hull, so look.
- Ask for the operator’s TAT licence number if you book on the beach.
- Do not let the captain overload the boat for a “quick extra stop”.
- Agree on the snorkel spot before you anchor, away from boat lanes.
- If the sea looks rough, accept the captain’s call to turn back.
Safety is where the cheapest beach deal can bite you. A straight-talking operator, a clean boat and proper life jackets are easily worth a few hundred baht.
Tour Providers and Booking Information
Comparing Tour Providers
Who does the private 4 island tour Krabi? Mostly the same online agencies that run shared tours, plus a few smaller charter specialists. What they published in September 2026:
| Provider | Private longtail | Private speedboat | Notes |
|---|---|---|---|
| Koh Tour Krabi | From ฿4,050 per group | From ฿10,995 | Lunch box ฿100 pp, guide ฿1,200, transfers extra outside Ao Nang |
| Viagotour (bigtourkrabi.com) | On request | ฿8,900 | Deposit option, pay rest in cash |
| Ao Nang Beach longtail counter | Around ฿6,000 advertised for 3–5 people, negotiable | — | Walk-up, cash |
| Krabi Castaway Tours and other charter specialists | Quote on request | Quote on request | Ask for a written itinerary and inclusions |
Compare what you get, not just the number. Boat size, hours on the water, inclusions, the three newest reviews. A “cheap” private longtail minus lunch, guide and transfers can easily end up costing more than the pricier all-inclusive one.
Booking and Availability
Checking availability is easy: pick a date on an operator’s site, choose “private”, and the calendar says whether a boat's free. Booking one goes like this:
- Choose longtail or speedboat and the group size.
- Pick a start time — 07:30–08:00 for empty beaches, or after 13:00 for sunset.
- Add extras: lunch, guide, transfers, fins.
- Pay the deposit and save the voucher and WhatsApp contact.
Season matters. Private boats are the first thing to sell out in late December, January and over Chinese New Year, so book a week ahead then. May–October, the day before is usually fine. You can also just walk up and charter on Ao Nang Beach; get the route, hours and price in writing before you step aboard. The booking guide covers the rest.
Cost and Additional Services
Understanding the Cost
A private boat tour costs four things: the boat charter, the park fee per head, transfers, and food and guiding.
| Component | Typical 2026 price |
|---|---|
| Private longtail charter | From ~฿4,050 (small group) to ~฿4,750 (about 8 people) |
| Private speedboat charter | ฿8,900–฿10,995 |
| National park fee | ฿200 per adult, ฿100 per child, cash |
| Lunch box | About ฿100 per person |
| English-speaking guide | About ฿1,200 per boat |
| Private transfers outside Ao Nang | About ฿500–฿1,200 per group |
What pushes the price around: season (December–February is firmest), group size (bigger boats cost more, less per head), hours on the water, where you get picked up. The per-person maths is what sells it. Koh Tour Krabi’s own listing works out at roughly ฿810 each for five people on a small longtail and about ฿594 each for eight. Both beat plenty of shared speedboat seats. So fill the boat. Bring your cousins.
Additional Services and Amenities
Extras you can add on a private charter:
- Lunch boxes or a restaurant lunch on Poda Island (vegetarian and halal options).
- Snorkeling gear — masks usually included, fins sometimes extra.
- A private English-speaking guide.
- Cool boxes with drinks and fruit.
- Cushions and shade on the bow deck.
The fancier stuff shows up on speedboat, catamaran and yacht charters. Towels, sunset drinks, a photographer, dinner on the beach. Charter specialists like Krabi Castaway Tours and the bigger agencies will quote for special packages too: proposals, birthdays, sunset plankton swims. Get all of it in writing.
Tour Itinerary and Experience
Duration and Itinerary Details
Typically a private 4 island tour means 4–6 hours on the water. Krabi Tours agencies and similar operators do half-day (about 4–5 hours) and full-day charters. Here's a sample early itinerary on a 4 Islands Private Longtail:
| Time | Stop | What you do |
|---|---|---|
| 07:30 | Ao Nang Beach | Board your private longtail |
| 07:50–08:40 | Phra Nang Cave Beach | Swim before the crowds arrive |
| 08:55–09:40 | Chicken Island | Snorkel the reef |
| 09:50–10:50 | Tup Island | Walk the sandbar at low tide |
| 11:00–12:30 | Poda Island | Lunch, swim, shade |
| 12:50 | Ao Nang | Back for the afternoon |
What makes a private day: an empty Phra Nang, the sandbar at exactly the right tide, nobody herding you back to the boat. If the charter runs longer, add Railay West. Or end with a sunset on Poda. I'd pick the sunset.
