The best islands to visit around Phuket in 2025

Why island hopping around Phuket is a must

Phuket serves as a convenient “hub” for exploring the surrounding archipelago in the Andaman Sea and Phang Nga Bay. Many of the region’s most iconic landscapes, pinnacles of limestone, hidden lagoons, vibrant reefs — lie just a short boat ride away.

Because Phuket is such a magnet for tourists, many day-trips and island-hopping tours depart from here, making access relatively easy and logistically viable.

Still, not all islands are equal in terms of crowd levels, distance, and what they offer, especially as tourism rebounds and demand grows. In 2025, being smart about when, where, and how long you visit will make all the difference in having a magical experience instead of a crowded one.

Below we break down islands by proximity, “must-see” status, and lesser-known gems, along with tips to help you choose what fits your style.

Major, well-known islands: essential visits

Koh Phi Phi (Phi Phi Don, Phi Phi Leh, Bamboo Island, etc.)

Why go: The Phi Phi group is arguably the most famous island cluster in southern Thailand. Dramatic limestone cliffs, clear bays like Pileh Lagoon, Maya Bay (when open), Monkey Beach, and plenty of snorkeling and diving opportunities make these islands perennial favorites.

What to expect in 2025: The islands remain very popular, so early departure times are advantageous to beat the crowds. Also, environmental regulations have become stricter — for example, Maya Bay has been periodically closed to visitors for ecological recovery (especially during certain months) to relieve pressure on marine life.

How to get there: Private Speedboat tours from Phuket are the common way to explore Phi Phi islands in style. The jounrey takes about 45-60mins one way. You can book a private speedboat with our company.

Tips:

• Stay overnight on Phi Phi Don if you have the time — you’ll get quieter dawn and dusk experiences when day-trippers leave.

• Check in advance whether Maya Bay is open (or closed) when you plan to visit.

• Book tours ahead in peak season (Nov–Apr) to secure good boats.

Phang Nga Bay islands (James Bond Island, Hong Island, etc.)

Why go: If you enjoy dramatic karst cliffs, mangrove caves, sea kayaking, and dramatic scenery, the islands in Phang Nga Bay are iconic. James Bond Island (Koh Tapu) is a classic postcard image.

What to expect in 2025: This area remains very popular with day-trip operators. Many tours also combine other nearby islands or hole-in caves (sea caves, lagoons).

How to get there: Our Phang Nga bay tours depart from Phuket by speedboat; you can also find combined tours that link with or other islands.

Tips:

• Do not miss our kayaking or cave canoeing tour at Phang Nga bay.

• Try to go in the morning when light is best and crowds are lighter.

• Bring insect repellent and sun protection, as some interior mangrove or cave areas can have mosquitoes.

Khai Islands: A Family-Friendly Paradise Near Phuket

Why go: The Khai Islands are especially popular with families and first-time snorkelers. The shallow waters teem with fish, and you can literally wade into the sea and be surrounded by schools of vibrant tropical species. The beaches are powdery white, and the gentle slope into the sea makes it safe for children to play and swim. Unlike some larger islands, the Khai group offers a more relaxed and intimate vibe, giving you the feeling of being on your own private beach escape.

What to expect in 2025: Facilities are simple but adequate, small beach cafés, sun loungers, and umbrellas are available, making it easy to spend a leisurely day. The popularity of the islands means they can get busy in the middle of the day, so arriving early in the morning or later in the afternoon ensures a quieter experience.

Tips for your visit:

• Bring reef-safe sunscreen and a GoPro or underwater camera — the snorkeling is excellent right off the beach.

• If you’re traveling with kids, Khai Nok is the most developed and family-oriented.

• Consider combining the Khai Islands with a stop at nearby Rang Yai for a diverse island-hopping day.

Koh Yao Noi & Koh Yao Yai

Why go: These islands in Phang Nga Bay are more relaxed, less overrun by large tours, and offer a more local, low-key vibe. You’ll find rice fields, villages, mangroves, and nature walks.

What to expect: Quiet beaches, slower pace, possible home stays or boutique resorts, local fishing villages, and a chance to see more rural life.

How to get there: Our Krabi island tours include Koh Yao islands as stops.

Tips:

• Stay at least one night to slow down and experience daily routines.

• Rent a scooter or bike to explore the interior.

• Be flexible with dining and services, options may be more limited compared to tourist hotspots.

Krabi Islands: Limestone Giants and Hidden Lagoons

A little further from Phuket but absolutely worth the journey, the Krabi Islands showcase some of Thailand’s most iconic seascapes. Towering limestone cliffs rise straight from emerald waters, concealing secret lagoons, caves, and perfect snorkeling spots. From the famous Hong Island and its breathtaking lagoon to smaller gems like Pak Bia, Lao Lading, and Phak Bia, the Krabi archipelago is a dream destination for both adventurers and photographers.

Why go: Unlike the busier Phi Phi, the Krabi islands balance natural beauty with a calmer pace. Hong Island is the star attraction, offering kayaking into its hidden lagoon — an unforgettable experience surrounded by cliffs so high they feel like natural walls. The smaller islands nearby provide pristine beaches and excellent snorkeling, while day tours often combine several stops to give you a complete taste of Krabi’s charm.

What to expect in 2025: Krabi’s national parks continue to enforce conservation rules, which keeps the islands cleaner and the reefs healthier. Expect designated swimming zones, eco-friendly kayak tours, and limits on the number of boats entering lagoons at any given time. While day-trippers from Phuket and Krabi Town ensure a steady stream of visitors, the atmosphere is still more tranquil than the Phi Phi group.

Tips for your visit:

• If possible, book a private speedboat tour to explore at your own pace.

• Don’t miss kayaking in Hong Lagoon at low tide when the hidden chamber is most accessible.

• For a truly special experience, consider an overnight tour that lets you wake up surrounded by Krabi’s limestone seascape, it’s far quieter once the day boats leave.

Koh Rang Yai & Koh Rang Noi

Why go: These islands just off Phuket’s east coast (north of Phuket Town) are quieter getaways for half-day escapes.

What to expect: A peaceful beach day, fewer crowds, maybe just a handful of restaurants or beach huts.

How to get there: Local longtail boat or small boat from piers on the east side of Phuket. Or book our private Speedboat for a island hopping tour including Rang Yai island.

Timing, seasons, and logistics to maximize your visit

Best time to go

Phuket’s “high season” typically runs from November to April, when weather is most favorable and seas are calmer (less rain, more sunshine). During May to October, monsoon influence can make sea crossings rough and rain more frequent.

However, even in the shoulder or off-peak months, mid-day sea conditions are often fine — especially closer islands. The trick is to check local forecasts, book with reputable operators, and build in buffer days in case a transfer is canceled or delayed.

Booking & tours in 2025

• Book in advance for popular islands (Phi Phi, Phang Nga Bay, etc.) during peak times, especially for morning departures.

• Be aware of any environmental closures or restricted access (e.g., Maya Bay closures).

Travel tips & reminders

• Sun & sea safety: Bring reef-safe sunscreen, a hat, water shoes or fins.

• Packing: Waterproof pouch, dry bag, light clothes, swimwear, insect repellent.

• Cash & essentials: Many smaller islands have limited ATM access; carry cash and basic supplies.

• Respect nature: Don’t touch coral, avoid boisterous behavior in reefs, and pack out your trash.

• Best times of day: Early morning and late afternoon offer better lighting, fewer crowds, and calmer seas.

  
  

Final thoughts

In 2025, traveling around Phuket offers more than just beach time — it’s a chance to connect with marine nature, explore dramatic landscapes, sample local communities, and get away from crowds (if you plan smartly). The trade-off is choosing which islands to prioritize, how far to venture, and when to go.

For first-time visitors or shorter stays, combining Phi Phi and Phang Nga gives you the highlights. If you have more time and an adventurous spirit, add Krabi islands and Yao islands to your list. And if you prefer quieter, slower rhythms, focus on the Yao islands, Racha, or the "middle" islands (like Rang Yai) where fewer tours intrude.
