Hong Islands (Koh Hong) Tour from Krabi: What to Know Before You Book

TL;DR: The Hong Islands (Koh Hong) day trip from Krabi centres on a hidden lagoon inside a limestone karst, called a ‘hong’ (room) in Thai, plus a roughly 400-step viewpoint hike with a 360-degree view over the Andaman Sea. A shared longtail boat tour runs about ฿1,000-1,245 (~US$30-38) per person and a shared speedboat about ฿1,300 (~US$39), both for a full day of around 6-7 hours, on top of a ฿300 (~US$9) Than Bok Khorani National Park fee for adults (฿150-200 / ~US$5-6 for children) that’s excluded from every tour price. Stops typically include Hong Island and its lagoon, Lao Lading Island, and Pakbia or Daeng Island for snorkelling, roughly 35-45 minutes from the mainland by longtail or 20-30 minutes by speedboat, noticeably further than the Krabi 4 Islands route. Compared with the 4 Islands tour, Hong Islands has fewer stops and a longer boat ride but a lower park fee, more dramatic limestone scenery, calmer beach-based snorkelling and the option to kayak. All prices ฿33 = US$1 (July 2026).

If you’ve searched “Hong Islands Krabi tour” or “Koh Hong tour,” you’ve probably seen the same striking photo: a longtail boat gliding into what looks like a secret room carved out of limestone, jungle-draped karst walls rising straight out of turquoise-green water. That’s the Hong itself, Thai for “room,” and it’s the reason this trip has become the main rival to the Krabi 4 Islands tour. This guide breaks down longtail versus speedboat pricing, the Than Bok Khorani National Park fee that catches people off guard, the roughly 400-step viewpoint hike, and a direct comparison with the 4 Islands route so you know which one, or both, to book. Every price and detail below is checked against current 2026 operator listings and national park fee schedules, sourced at the end.

What’s included in a Hong Islands tour?

A standard full-day tour includes hotel or pier transfer within the Ao Nang zone, a guide, snorkelling gear (mask, snorkel, life jacket), lunch, fruit and drinking water, the same core inclusions as Krabi’s other classic day trips. What it doesn’t include is the Than Bok Khorani National Park entrance fee, which is collected separately in cash rather than folded into the advertised tour price. Pickup from further out, in Krabi Town, Klong Muang or Tubkaek, usually carries an extra transfer charge on top of the standard price; the amount varies by operator, so confirm it when you book rather than assume it’s included.

Hong Islands tour options compared

National park fee (฿300 / ~US$9 adult, ฿150-200 / ~US$5-6 child) is additional on every option above. Prices compiled from Krabi tour operator listings; see Sources.

What is the Hong, and why does everyone want to see it?

The Hong is an enclosed lagoon inside Hong Island’s limestone karst, reached through a narrow rock channel, and it’s the single most-photographed stop on the tour. Hong means “room” in Thai, and the name describes exactly what you find: a sheltered pool of turquoise-green water walled in on all sides by sheer, jungle-draped cliffs, open only through a slim gap in the rock that boats and kayaks squeeze through. Water colour and depth inside change with the tide; at low tide you can see the sandy lagoon floor and fish moving through it, at high tide it reads as a deeper green-blue. Most tours give you roughly 20-30 minutes inside the lagoon to swim, wade or paddle before moving on.

The Hong Island viewpoint hike

The viewpoint trail climbs roughly 400 steps (commonly cited as 419 metal stairs) from the beach and takes about 15-20 minutes up at a normal pace. It’s mostly shaded, which helps, but the combination of heat, humidity and a genuine incline makes it more tiring than the step count alone suggests, so wear shoes with grip since the steps can be slick after rain. At the top, two viewing platforms look out over the surrounding limestone islands and the Andaman Sea, with Koh Phi Phi visible in the distance on a clear day. Not every tour schedule leaves enough time for the hike, so if the view is a priority, ask your operator how long you’ll actually have on Hong Island before booking.

Which islands does the tour actually visit?

A standard Hong Islands tour centres on Hong Island itself and typically adds one or two nearby stops: Lao Lading Island and either Pakbia Island or Daeng Island. Hong Island is where the lagoon and viewpoint are; Lao Lading has a couple of small, sandy beaches with clear, calm water; Pakbia and Daeng are used mainly as snorkelling stops. Some operators build a short kayaking session around Hong’s coves into the standard day, rather than as a paid extra, though this varies by tour. Because the exact secondary stops differ between operators, check the listed itinerary if a specific island matters to you.

What about the national park fee?

Expect to pay ฿300 (~US$9) per adult and roughly ฿150-200 (~US$5-6) per child, in cash, on top of the tour price. Hong Island sits inside Than Bok Khorani National Park, so this is a government park entrance charge, not a tour company markup, and by regulation it can’t be bundled into the advertised rate. Your guide collects it from the group in cash, usually before or right after landing, so bring small baht notes since large bills can be hard for a guide to break for a full boatload of tourists. For comparison, this is actually lower than the ฿400 (~US$12) adult fee for the Mu Ko Poda park that covers the Krabi 4 Islands route, despite Hong being the longer boat trip.

Longtail or speedboat?

Speedboat gets you there faster and leaves more time on the islands; longtail is slower, cheaper and better suited to the narrow lagoon channel. A shared longtail runs about ฿1,000-1,245 (~US$30-38) per person for a crossing that operator comparisons put at roughly 35-45 minutes each way, versus about ฿1,300 (~US$39) and 20-30 minutes by speedboat. Longtail boats also have a shallower draft, which matters for getting into Hong’s lagoon channel at some tide levels, and their open, low-slung design gives an unobstructed view of the karst scenery on the way in. If you get seasick easily, or want to maximise time on the islands rather than in transit, the speedboat is worth the difference; if budget and atmosphere matter more, longtail is a perfectly good choice.

Hong Islands vs Krabi 4 Islands: which should you book?

Book the 4 Islands tour for a shorter ride and the classic Krabi postcard stops; book Hong Islands for one dramatic lagoon, a real hike and calmer snorkelling. The two tours depart from the same general area but go in different directions and have a genuinely different feel, so the right pick depends on what you want out of the day.

Both routes see similar volumes of daily tour traffic, so neither is meaningfully quieter than the other on an average day. If you only have one day in Krabi and want the highest-recognition photos, the Tup sandbar, Phra Nang Cave, pick the 4 Islands. If you’d rather trade some variety for one striking limestone lagoon and an actual hike with a payoff view, pick Hong Islands. With three or more days in the area, most travellers who do both come away glad they didn’t skip either, per Krabi tour operator comparisons.

Best time to go, and how to avoid the crowds

November to April is the recommended season, with December to March offering the calmest seas and clearest lagoon visibility. Monsoon season, roughly June to October, brings rougher crossings that can delay, reroute or cancel the trip, along with reduced visibility in the water. Most tour boats arrive in a similar 9am-12pm wave, so the lagoon and viewpoint can queue up fast in that window; arriving with an early or private departure noticeably thins the crowd, according to on-the-ground travel guides.

What should you bring?

• Reef-safe sunscreen (regular sunscreen is discouraged near the reef and lagoon areas on most Krabi tours)
• Shoes with grip for the roughly 400-step viewpoint climb (the steps can be slick after rain)
• A hat, sunglasses with a strap, and swimwear or a rash guard
• A dry bag or waterproof phone pouch, since you’re in and out of boats and water most of the day
• Cash in small baht notes for the national park fee
• A change of clothes for the boat ride back

Honest downsides

Hong Islands earns its reputation, but go in with realistic expectations.

• The boat ride is genuinely longer. At 35-45 minutes each way by longtail, you spend noticeably more time in transit than on the 4 Islands route, which cuts into time actually spent on the islands.
• It gets crowded too. Hong Islands is not a quiet alternative to the 4 Islands tour; most operators run the same 9am-12pm departure window, so the lagoon and viewpoint see similar boat traffic at peak times.
• The viewpoint hike isn’t for everyone. Roughly 400 steps in Krabi’s heat and humidity is more demanding than it sounds, and not every tour schedule leaves enough time to do it properly.
• The lagoon is tide-dependent. Water clarity, and how much of the “room” you can actually explore by boat or kayak, shifts with the tide, so the experience varies day to day.
• Snorkelling is easy, not spectacular. Shallow, beach-entry snorkelling suits beginners and families, but it won’t impress anyone chasing serious reef life.
• Weather can cancel or reroute the trip. The June-October monsoon brings rough seas that can delay departures or cancel the trip outright, same as most Krabi boat tours.

Bottom line

Hong Islands delivers what its name promises: one genuinely striking, enclosed lagoon, a hike with a real payoff view, and calmer, easier snorkelling than the 4 Islands route, in exchange for a longer boat ride and a similar level of crowding at peak hours. Book a longtail if budget and atmosphere matter more than speed, pay the extra for speedboat if you’d rather spend the saved time on the islands, and budget separately for the ฿300 (~US$9) Than Bok Khorani park fee.
