Visit the monumental 12-metre golden Big Buddha Temple rising over a rocky island ridge, then Wat Plai Laem with its 18-arm Guanyin statue over a fish-filled lake.

A private 60-foot luxury sailing yacht sunset cruise past the pristine Koh Som coast, chilled champagne served on deck as the Gulf turns gold.

Breakfast, Lunch, Dinner

Day 4 | Island Archipelagos from the Sky & Hidden Bars

Rising before dawn for a private doors-off helicopter flight tracking the ring of barrier reefs and tiny jungle islets, the coral reefs visible through turquoise water below.

After landing, transfer to a completely isolated sandbar for a white-linen hot breakfast set up by the private crew — the water gently lapping at the edge of the table.

Koh Phangan

A private high-speed dive vessel to Koh Tao for crowd-free scuba diving or snorkelling at Shark Island and Hin Wong Pinnacle — vibrant coral walls, sea turtles, and shimmering schools of fusiliers.

Possibility of black-tip reef sharks, hawksbill turtles, and whale sharks. Private dive master guides through the best sites.

Day 7 | Coral Walls of Koh Tao

Day 8 | Jungle Spa & Bonfire Star Dinner

A peaceful day at the resort with a traditional coconut-oil scrub at the jungle spa using local organic ingredients.

Inclusions & Price

Deposit Offer

Hold 2027 for half the usual deposit

Confirm any 2027 departure with a 15% deposit instead of the usual 30%, booked before 31 December 2026.

  • Your balance is not due until 60 days before departure.
  • The reduced deposit holds your camps, permits and internal flights at today’s rates, so a mid-year price movement does not reach you.
  • Applies to new 2027 bookings only and cannot be combined with a group discount on the same booking.
Solo Travellers

30% off the single supplement

Travelling on your own? We cut the single traveller supplement by 30% across selected 2027 departures.

  • The supplement covers the sole-occupancy cost a camp charges when a room sleeps one rather than two.
  • Available on selected camps and dates — your specialist will tell you which of your nights qualify before you commit.
  • Nothing changes about the journey itself: same guide, same vehicle, same rooms.
Group Offer

Bring three, the fourth travels free

Book four guests on a 2027 group departure and the fourth guest’s safari cost is on us.

  • The waiver covers the land portion — camps, meals, guiding and game drives.
  • International flights, visas, gorilla and chimpanzee permits and personal spending are excluded, as those are paid to third parties per head.
  • All four guests must travel on the same departure date and book together.

Journey Details

Travel Kit

Duffel, sun hat, rain shell and day pack

  • Your duffel — A soft-sided Finders & Keepers Safaris duffel, sized for domestic flights and easier than a hard case on train platforms, ferry jetties and old-town lanes.
  • What is inside it — A wide-brim sun hat, a lightweight packable rain shell for tropical downpours, and a foldable day pack for temple mornings and market afternoons.
  • Yours to keep — The bag and everything in it is a gift, not a loan.
  • Packing around it — Slip-on shoes save time at temples, where you remove them repeatedly, and one set of clothing covering shoulders and knees is essential for religious sites.

Note

Monsoon timing varies by coast

The Andaman coast (Phuket, Krabi) and Gulf coast (Koh Samui) have opposite monsoon patterns, so the ideal season depends on which coast your itinerary includes.

  • Early starts — The best of this journey happens at dawn — before the heat, the crowds and the haze. Your guide will confirm what time you will be collected from your hotel.
  • Tailoring this journey — If you would like this package with more or fewer days, arranged for a group, a family or a solo traveller, or with add-ons, reach out and we will tailor it for you.
  • Route changes — Your guide or driver may alter the route in certain circumstances, but every destination set out in the itinerary will be covered.

Documents

Visa-free for most nationalities

  • Passport — Valid for at least six months beyond your arrival date, with at least two blank pages for stamps.
  • Visa exemption — UK, EU, US, Canadian, Australian and some ninety other nationalities enter under a 60-day visa exemption, extendable once by a further 30 days in country.
  • Digital Arrival Card — The TDAC is compulsory for every foreign arrival by air, land or sea and must be filed within the 72 hours before you travel. It is free.
  • Proof of onward travel — Airlines routinely refuse boarding without a confirmed onward ticket inside your permitted stay.
  • Medication — Several common codeine and pseudoephedrine medicines are controlled substances in Thailand. Carry prescriptions in their original packaging with a doctor’s letter.
  • We handle the paperwork — We complete and submit your visa, eVisa or travel-authorisation applications on your behalf. You supply the documents once; we do the filing, track the approval and hold the confirmations for you.
  • Where you must appear in person — A few consulates insist on biometrics or a short interview that nobody can sit on your behalf — China requires fingerprinting for some nationalities, as do European and United States visas. We still prepare the entire file; we simply book you a single appointment and brief you beforehand so one visit settles it.
  • Before you travel — Entry rules change frequently and without much notice. Your specialist confirms the current requirements for every passport in your party at the time of booking, and checks them again before you fly.

Guaranteed Departures

Private, tailor-made departures on your dates, or join a small group

  • Once confirmed, you travel — When your departure date is confirmed, it is guaranteed. We do not cancel, merge or reschedule a confirmed departure for commercial reasons, however the final numbers fall.
  • What confirms a departure — A departure becomes confirmed once the agreed number of travellers has been reached and paid for in line with the agreed payment schedule. Places held without payment do not count towards it.
  • If the minimum is not reached — Where a group departure has not reached its agreed numbers, we tell you early rather than late, and you choose: move to the next available date, continue at a revised small-group rate, or take a full refund of everything you have paid.
  • Solo journeys — Solo and tailor-made itineraries carry no group minimum at all. Your dates are confirmed the moment your deposit is received.

A deposit of 30% is required to confirm your booking, with the balance due 60 days before departure. All itineraries can be tailored — extend a stay, add a destination, or adjust the pace to suit you. Comprehensive travel insurance covering trip cancellation, medical evacuation and personal effects is required for all guests. Your dedicated specialist remains on call throughout your journey for any changes or assistance you need.

  • What to pack — Light layers and slip-on shoes, which you will take off repeatedly at temples, shrines and traditional inns. Shoulders and knees must be covered to enter most religious sites, so pack at least one modest set you can throw on. A light rain shell handles the tropical downpours, and the highlands and northern cities run far cooler than the coast — bring a proper warm layer if your route climbs.
