Krabi Island Comparison: All the Main Options Laid Out

Krabi sits in the middle of some of the best island scenery in Southeast Asia. The problem is working out where to actually go. Most visitors have two or three days at most, and everyone online seems to have a different favourite. This guide walks through the main options, including where the hype outruns the reality, so you can pick the right one for your trip.

Quick comparison

If you just want the short version, here is the shape of each place at a glance.

Now the honest version of each one.

The Hong Islands (Koh Hong group)

The Hong Islands are a small cluster inside the Hat Noppharat Thara, Mu Ko Phi Phi National Park, roughly 8 kilometres from Ao Nang. The main island, Koh Hong, is famous for a hidden lagoon (locals call it "the room") enclosed by limestone cliffs. You reach the lagoon through a narrow gap in the rock and the whole thing opens out into a calm saltwater pool with sheer walls on every side. It's the kind of thing that sounds overhyped until you see it in person.

Koh Hong is the best day trip in the Krabi area if you want a mix of swimming, snorkeling, beach time, and a bit of an adventure with the lagoon. The water around the islands stays clear most of the year, the reefs are healthy, and the crowds are much lighter than Phi Phi. There is a 360-degree viewpoint at the top of Koh Hong itself (419 metal steps, built in 2020) that gives you a panoramic view across Phang Nga Bay on a clear day.

You can't stay overnight. The islands are inside a national park and commercial activity is limited, so all visits are day trips. Most tours leave Ao Nang between 9 and 10 in the morning and return in the mid-afternoon. There are longtail options (cheaper, slower, more atmospheric) and speedboat options (faster, covers more stops including Lao Lading, Lao Ka and Pakbia).

Best for

• Day trippers staying in Ao Nang or Krabi Town
• Families who want something to do that isn't just a beach
• Snorkelers and photographers
• Anyone who wants to see the "hidden lagoon" everyone posts on Instagram

Skip it if

• You are staying on Phi Phi already (Koh Hong is a separate trip from the other side of the mainland)
• You want to stay overnight on an island
• You are chasing the nightlife scene

Phi Phi Islands

Phi Phi is the most famous island group in the Krabi area, mostly thanks to Maya Bay appearing in The Beach with Leonardo DiCaprio back in the early 2000s. Phi Phi Don is the main inhabited island, with hotels, bars, restaurants and ferry connections to Krabi and Phuket. Phi Phi Leh is the uninhabited one with Maya Bay, Loh Samah Bay and the Viking Cave.

Phi Phi is beautiful, no argument. The limestone cliffs dropping into turquoise water, the shape of Maya Bay, the sunset views from Phi Phi Don's viewpoint, all of it looks like the photos. The catch is that everyone knows that. Day trip boats from Phuket, Krabi, Koh Lanta and Ao Nang all converge on Phi Phi Leh around 11am, and Maya Bay can have dozens of boats parked at the entrance at once. The authorities closed Maya Bay for three years (2018-2021) to give the reef a chance to recover.

Best for

• Travellers who want to stay overnight on an island with a party scene
• Honeymooners booking a resort on Phi Phi Don's quieter side
• Anyone who considers seeing Maya Bay a bucket list item

Skip it if

• Crowds ruin your enjoyment
• You want quiet snorkeling (it exists, but you have to time it before or after the rush)
• You only have one day trip and want the best experience for your baht

Railay Beach

Railay isn't technically an island, it's a peninsula. But the cliffs around it cut it off completely from the mainland, so the only way in is by longtail boat. The ride from Ao Nang takes about 15 minutes and costs a few hundred baht.

There are actually four beaches in the Railay area. West Railay is the postcard one, a wide strip of soft sand backed by cliffs. East Railay is a mangrove side with the cheap accommodation and bars. Phra Nang is the most beautiful, a tiny beach tucked under a cliff, with a cave at one end. Tonsai is the climbers' beach, rougher and more alternative in vibe.

Railay is a place you relax at, not so much do things at. It has a few caves to explore, Phra Nang cave, some viewpoints, and a big rock climbing scene. The snorkeling is mediocre, the sea floor is mostly sand, and the water can be cloudy depending on tide and season. If you're comparing on snorkeling alone, Railay loses to Koh Hong easily.

Best for

• Couples who want a quiet beach with good food nearby
• Rock climbers (it's one of the best spots in Asia)
• Travellers who want one day completely off-schedule

Skip it if

• You want to snorkel, Koh Hong is better
• You prefer beaches with lots of shade and calm shallows
• You're a budget traveller during peak season, prices get silly

Koh Lanta

Koh Lanta is for people who want to stay longer. It's bigger than the other islands, about 27 kilometres long, with a mix of beaches, jungle, a small national park at the southern tip, and enough restaurants and cafes to keep you busy for a week. The vibe is much more laid-back than Phi Phi, and significantly less touristed than Railay.

Getting there takes effort, which is part of why it stays quieter. The ferry from Krabi Town takes about 2 hours and only runs in high season. A minivan plus ferry combo takes a similar time. Once you're there, you're basically staying until your next stop, because day-tripping in and out of Lanta doesn't work well.

Lanta is not a day trip destination. It's a "base yourself here for 4-7 nights and explore slowly" destination. If your trip is mostly day trips from Krabi, Lanta is not your pick. If you want to slow down, it absolutely is.

Best for

• Longer stays (4 nights or more)
• Travellers who want a calm island base with some local life
• Couples, remote workers, anyone who's tired of the usual Krabi tour circuit

Koh Jum and the quiet ones

Koh Jum is between Krabi and Koh Lanta and is what Lanta used to be about 20 years ago. Very little development, mostly small family-run bungalows, no banks, no 7-Eleven, limited electricity at some of the smaller resorts. It's the off-grid option for people who want to disappear.

Koh Jum works best as a 3-5 night stay with a day trip or two. Don't come for the nightlife, don't come for the infrastructure, come for the quiet. Ferries run twice a day in high season and not at all for a big chunk of low season.

Other "escape the crowds" options in the area include Koh Yao Noi and Koh Yao Yai (between Krabi and Phuket, bigger, more family-friendly) and Koh Ngai (further south, even quieter than Jum). Each has a different flavour but they all share the same basic philosophy of "less is more."

So which one should you pick?

It depends entirely on how long you have in Krabi and what you actually want. Here is how to think about it.

If you have one day

Go to the Hong Islands. It is the best day trip in the area by a clear margin, it has the best mix of swimming, snorkeling, scenery and uniqueness for the time invested, and it's close enough that you don't lose half the day in transit. Book the longtail tour if you want the classic Thai experience, or the speedboat if you want more stops in less time. See our Hong Islands tours.

If you have two days

Day 1: Hong Islands. Day 2: Railay Beach. These two together give you a bit of everything: the lagoon and snorkeling action on day one, a relaxed cliff-beach day on day two. You can do Railay as a day trip (cheap longtail from Ao Nang) or stay overnight if you want a different vibe from wherever you're based.

If you have three days or more

Add Phi Phi if you want to see Maya Bay. Book early morning or late afternoon boats to avoid the midday crowds, or better yet, stay overnight on Phi Phi Don so you're on the island before the day boats arrive. Alternatively, use the extra day to explore the mainland (Tiger Cave Temple, Emerald Pool, hot springs, Ao Thalane mangroves) which is usually underrated.

If you have a week or more

Consider splitting your time between Krabi (day trips to Hong, Railay, maybe Phi Phi) and a base on Koh Lanta or Koh Jum for a slower second half. Krabi gives you the excitement and Lanta/Jum gives you the wind-down. It's the combination most repeat visitors recommend.
