Essential Travel Tips for Visiting Thailand’s Islands

Before diving into which island is best for your travel style, it helps to know a few key things about how to plan your trip. From weather patterns to getting around, here are the essentials to keep in mind.

When Is the Best Time to Visit the Thai Islands?

Thailand’s islands have two main seasons and are split between two coasts, which don’t share the same weather patterns:

  • Andaman Sea (West Coast) – Includes Phuket, Krabi, Koh Phi Phi, Koh Lanta
    Best time to visit: November to April (dry, sunny days)
    Rainy season: May to October, with heavy afternoon downpours and rougher seas

  • Gulf of Thailand (East Coast) – Includes Koh Samui, Koh Phangan, Koh Tao
    Best time to visit: January to September
    Rainy season: October to December, although showers tend to be short

If you're planning to go island hopping, it’s usually best to stick to one coast depending on the season.

Getting Around the Islands

Thailand makes island-hopping fairly simple, with multiple transport options depending on your budget and route:

  • Ferries and Speedboats: The most common way to travel between islands. Book in advance during peak season. Companies like Lomprayah and Seatran run reliable services.

  • Domestic Flights: Useful if you're short on time. Airports on Phuket, Krabi, and Koh Samui connect to Bangkok and other cities.

  • Minivans + Ferries: A budget-friendly way to get to islands from cities like Bangkok or Chiang Mai.

Tip: Use services like 12Go Asia to check routes, times, and book tickets in advance.

Should You Island Hop or Stay Put?

It depends on how much time you have:

  • 1 week or less: Choose one island and explore it fully

  • 10–14 days: Combine two or three nearby islands (e.g. Koh Samui → Koh Phangan → Koh Tao)

  • Longer trips: Mix coasts if the season allows, or go off the beaten path

Entry Requirements and Visas

For most nationalities, Thailand offers visa-free entry for 30–60 days (depending on your passport). Always double-check before you fly. Extensions are possible from within Thailand if you want to stay longer.

Find Your Perfect Thai Island: A Guide by Travel Style

Thailand's islands are as diverse as the travellers who visit them. Whether you're looking to dance until sunrise, unwind in peace, or explore underwater worlds, there’s a Thai island that fits your style perfectly. Below are hand-picked recommendations based on what kind of trip you're after.

For Party Lovers: Koh Phangan

Why go: Known globally for the Full Moon Party, Koh Phangan is the heart of Thailand’s island party scene. But there’s more than just one wild night—expect fire shows, beach raves, and plenty of late-night action across the island.

Best beaches for nightlife: Haad Rin (Full Moon central), Ban Tai, Haad Yuan (accessible only by boat)

Other highlights:

  • Black Moon, Half Moon, and Jungle Experience parties

  • Sunset bars and live DJ sets

  • Affordable beach bungalows and party hostels

Need to know: Avoid visiting during major party dates if you’re not into the scene—some areas can be loud and crowded.

For Wellness and Yoga Seekers: Koh Phangan (North) or Koh Yao Noi

Why go: The northern and eastern coasts of Koh Phangan are a world away from the party scene. Quiet, serene, and filled with wellness retreats, it’s a hub for digital detoxes, healing therapies, and yoga by the sea. Koh Yao Noi, closer to Phuket, offers similar peaceful vibes with a more exclusive feel.

Top spots:

  • Srithanu village (Koh Phangan) – yoga studios and vegan cafés

  • Island Yoga (Koh Yao Noi) – laid-back retreats in nature

Other highlights:

  • Thai massage courses

  • Herbal steam saunas

  • Plant-based restaurants and beachside meditation

For Honeymooners and Couples: Koh Lipe or Koh Yao Yai

Why go: Looking for romantic sunsets, quiet beaches, and boutique stays? These islands offer just that. Koh Lipe, near the Malaysian border, is all about white sand and turquoise water. Koh Yao Yai (and its sister island, Koh Yao Noi) offer a more local, luxury escape with far fewer tourists.

Best for:

  • Private beachfront villas

  • Couples kayaking and snorkelling

  • Candlelit seafood dinners by the shore

Travel tip: These islands are slightly harder to reach but well worth the journey for peace and seclusion.

For Backpackers: Koh Tao or Koh Phi Phi

Why go: Budget-friendly stays, lively nightlife, and a strong sense of community make these islands a hit with backpackers. Koh Tao is especially popular with travellers learning to dive, while Phi Phi combines social hostels with epic views.

Top things to do:

  • Get PADI certified on Koh Tao (some of the cheapest diving in the world)

  • Hike to Phi Phi Viewpoint for sunrise

  • Meet fellow travellers at beach bars and fire shows

Budget tip: Stay in dorms or fan bungalows to keep costs low, and eat at local markets instead of tourist restaurants.

For Budget Travellers: Koh Chang or Koh Lanta

Why go: These larger islands have a relaxed pace, good infrastructure, and a range of cheap guesthouses, hostels, and street food options—perfect for saving cash without missing out on experiences.

What to expect:

  • Beautiful waterfalls and national parks (especially on Koh Chang)

  • Quiet, spacious beaches

  • Scooter-friendly roads to explore independently

Ideal for: Long-term travellers, digital nomads, and anyone seeking value for money.

For Luxury and Comfort Seekers: Koh Samui

Why go: One of Thailand’s most developed islands, Koh Samui blends five-star resorts with fine dining, beach clubs, and wellness facilities. It’s also incredibly accessible, with its own airport and regular connections to Bangkok.

Luxury highlights:

  • Spa treatments and private pool villas

  • Brunch spots, wine bars, and chef-led restaurants

  • Yoga, golf, and private boat charters

Insider tip: Base yourself in quieter areas like Mae Nam or Choeng Mon for a more refined experience.

For Off-the-Beaten-Path Explorers: Koh Kood or Koh Mak

Why go: Far from the party crowd and tourist routes, these eastern islands near the Cambodian border are all about unspoiled nature, barefoot luxury, and a slow, meaningful pace.

Expect:

  • Empty beaches and clear water

  • Wooden piers, waterfalls, and mangrove forests

  • A small number of eco-resorts and family-run stays

Good to know: These islands take longer to reach and have limited infrastructure—but that’s exactly the point.

Final Tips and Travel Hacks for Exploring Thailand’s Islands

Before you pack your bags and head for the tropics, here are a few insider tips to help make your island adventure smoother, cheaper, and more enjoyable.

Book Transport in Advance During Peak Season

Ferries and flights between the islands can fill up fast during December to March and around Thai holidays. Use platforms like 12Go Asia or direct ferry company websites to lock in your seats—especially if you're moving between multiple islands.

If you're flying into Koh Samui, book well in advance—flights are limited and often pricey due to its private airport.

Don’t Over-Island Hop

It’s tempting to try to see everything, but too much island-hopping can eat into your time with boat rides, transfers, and packing/unpacking. For trips under 10 days, stick to 2–3 islands max, and choose ones that are logistically close together (like Koh Samui → Koh Phangan → Koh Tao).

Travel Light (Seriously)

Ferries, speedboats, and island roads aren’t made for massive suitcases. Pack light, opt for a backpack or soft duffel, and include:

  • Quick-dry towel

  • Reef-safe sunscreen

  • Dry bag for boat trips

  • Water shoes or sandals with grip

  • Light layers for island breezes or AC

Carry Cash—and Don’t Rely on One ATM

Many islands, especially smaller ones like Koh Mak or Koh Kood, have limited ATMs. Bring enough Thai baht to cover your first few days, and be aware that card payments might not be accepted in smaller guesthouses or restaurants.

Download Offline Maps

Internet coverage is decent but patchy in some areas. Google Maps or Maps.me with offline downloads can save you a lot of stress—especially when finding your accommodation or hiking a trail.

Watch the Weather—but Don’t Panic Over Rain

Tropical weather changes fast. A “rainy” forecast doesn’t always mean non-stop showers. Often, it’s a quick downpour followed by sunshine. Keep plans flexible and bring a light rain jacket or poncho, just in case.

Respect Local Culture and Island Life

Even the busiest islands have traditional roots. Dress modestly when away from the beach, learn a few Thai phrases (like sawasdee for hello and khop khun for thank you), and avoid stepping on coral or disturbing wildlife while snorkelling.
