Recommended by us
Namtok Ron Khlong Thom
Warm spring water cascades through a series of natural rock pools, different to any waterfall you've visited before. About an hour from Koh Jum by longtail and road.
Tiger Cave Temple
Climb 1,260 steps to a viewpoint that looks out over Krabi and the Andaman. The Buddha footprint at the top makes it a pilgrimage for Thai visitors. Go at dawn before the heat.
Emerald Pool
A spring-fed turquoise pool in the middle of lowland rainforest, a day trip from the island. Go early (before 9am) before the tour groups arrive from Krabi.
Krabi 4 Island sunset cruise
A 4.9 from 1,934 guests: four islands by longtail ending with a bioluminescent night swim. The Koh Jum equivalent of a proper Krabi evening out.
Krabi jungle tour
A 4.7 from 337 guests: hot springs, the Emerald Pool, and Tiger Cave Temple in one day. Saves renting a scooter for three separate trips.
Get to Koh Jum
Fly into Krabi, then take a taxi to Laem Kruat pier and the longtail ferry across, about 30 minutes on the water.

When to go
Koh Jum
Gulf coast · Koh Samui, Koh Phangan, Koh Tao
From June to September, Koh Jum is in its rainy season while the Gulf coast has its best months. Compare the two coasts
Nov–Feb Calm seas mean the longtails from Klong Jirad Pier and Koh Lanta run reliably. Koh Jum draws a quieter crowd than Phi Phi, uncrowded beaches and clear water with no jet-ski noise.
Mar–Apr Warm and still pleasant; boat connections remain dependable. A good time to find your own patch of beach without peak-season prices. The island stays calm even when Songkran grips the mainland.
May–Oct Several small resorts close entirely for the low season. Boat schedules thin out as seas become unpredictable. If you're happy with solitude and cheaper rates, a few guesthouses stay open.

About Koh Jum
Last updated June 2026
Picture a small island where fishing boats still outnumber tourist boats, where you can walk the entire coastline in a day, and where the biggest decision is which empty beach to claim as your own. That’s Koh Jum, a laid-back island in Krabi province that attracts travelers seeking authentic Thai island life without the crowds. This Andaman Sea hideaway draws visitors who prefer hammocks to nightclubs, local seafood shacks to resort restaurants, and dirt roads to tuk-tuk traffic. Within Krabi’s island collection, Koh Jum sits between the popular Phi Phi Islands and Koh Lanta, offering the perfect middle ground of accessibility and tranquility.
Top Things To Do
Days on Koh Jum revolve around the coast and the fishing village life that still shapes the island’s character. The beaches on the western and northern sides of the island stay quiet even in peak season. Snorkelling off the beaches and longtail boat trips to nearby reefs are the main water activities. Walking or cycling through the villages gives you a look at a way of life little changed by tourism. Its small rivers and canals make for good kayaking. Many visitors simply move between beach, hammock, and the small cluster of restaurants near the main pier.
Where To Stay
Koh Jum has a small number of beachfront bungalow resorts and guesthouses on the northern and western coasts. Accommodation runs from simple bamboo bungalows to small boutique resorts; there are no large hotel chains on the island. During peak season (November through April) the better properties book out, so reserving ahead is worthwhile.
Getting There
The island sits in Krabi province between the Phi Phi Islands and Koh Lanta. Longtail boats and speedboats run from Krabi Town’s Klong Jirad Pier and from Koh Lanta; schedules increase during the dry season. Most travelers fly into Krabi Airport, transfer to the pier, and take the boat crossing from there.
Best Time To Visit
Koh Jum sits on Thailand’s Andaman coast, which means the wet season runs from May through October. Plan your visit between November and April for the best weather - sunny days, calm seas perfect for swimming, and minimal rainfall. The dry season offers ideal conditions for exploring the island and enjoying beach time. December through February brings the coolest temperatures and lowest humidity, though this is also peak season. March and April get quite hot but remain dry.
Practical Tips
As a small island, Koh Jum likely has limited ATM access, so bring sufficient cash from Krabi or the mainland. English may be less common than on more touristy islands - basic Thai phrases help with local interactions. Transportation around the island would typically be on foot, bicycle, or motorcycle taxi on smaller roads. The island’s fishing village character means casual dress is appropriate, though respect local customs when visiting any religious sites.
Insider Tip: The island splits into a busier north end (near the main pier) and a quieter south end. Arriving on the first morning ferry from Krabi gives you the beaches largely to yourself before any day visitors arrive.
