Phi Phi vs Similan: which island suits your trip?
Choose Similan for world-class diving and pristine, crowd-free beaches. Choose Phi Phi for easy access, white-sand bays, lively nightlife, and the flexibility of a day trip from Phuket or Krabi. Both are stunning, but they serve very different travellers.
- Best for divers and nature lovers: Similan Islands (Mu Ko Similan National Park) — remote, biodiverse, and genuinely untouched.
- Best for beach-lovers, backpackers, and first-time island-hoppers: Koh Phi Phi — accessible, social, and packed with things to do above the waterline.
- Seasonality split: Similan is closed May through October each year; Phi Phi runs year-round, though rough-season cancellations happen.
Quick pick: One day and you want beaches? Go Phi Phi. One day and you dive? Go Similan. Have two days? Do both, on separate days.
Key takeaways
Phi Phi suits most travellers for beaches, snorkelling, and easy access; Similan is the right choice for serious divers and anyone who values pristine, crowd-free nature during the November–April window.

Phi Phi vs Similan: the key differences at a glance
The two clusters sit in opposite directions from Phuket, attract different crowds, and reward different priorities. Here is how they stack up across the dimensions that actually matter for planning.
| Dimension | Phi Phi Islands | Similan Islands |
|---|---|---|
| Best for | Beach-lovers, couples, backpackers, nightlife | Divers, snorkellers, nature lovers, solitude-seekers |
| Top activities | Snorkelling, swimming, hiking, kayaking, nightlife | Scuba diving, snorkelling, short hikes, wildlife spotting |
| Launch point | Phuket or Krabi | Khao Lak (primary); Phuket (longer) |
| Travel time | ~90 min by speedboat from Phuket | ~60–90 min by speedboat from Khao Lak |
| Crowds & vibe | Generally busy with a lively, party-friendly atmosphere | Remote, quiet, minimal infrastructure |
| Season & access | Open year-round; tours may be cancelled during the monsoon months | Open November–April only |
| Typical trip length | Day trip or 1–2 nights | Day trip or 2–6 night liveaboard |
| Cost range | 1,500–4,000 Baht (day trip) | Higher; park fees + longer transfers + liveaboard costs |
| Marine life | Good snorkelling; coral and reef fish | Exceptional diving; 500+ fish species, manta rays |
Quick takeaways:
- Phi Phi is the easier, cheaper, more social option — and it works for almost any traveller type.
- Similan demands more planning, more budget, and a specific travel window, but the underwater world is in a different league.
- Similan trips generally cost more than Phi Phi visits, reflecting park fees, longer transfers, and liveaboard pricing.
What to expect on the Phi Phi Islands
Koh Phi Phi is actually two islands. Koh Phi Phi Don is the inhabited one, with guesthouses, beach bars, fire shows at Tonsai, and a viewpoint hike that rewards you with one of the best panoramas in southern Thailand. Koh Phi Phi Leh is uninhabited and home to Maya Bay, the cove made famous by the film The Beach, which now operates with timed-entry access to protect the recovering coral.
Core highlights:
- Maya Bay (Phi Phi Leh): iconic limestone cliffs, turquoise water, and a strict daily visitor limit to manage reef recovery.
- Pileh Lagoon and Loh Samah Bay: calm, sheltered water ideal for snorkelling and swimming.
- Monkey Beach: a short longtail ride from Tonsai; wild macaques and clear shallows.
- Bamboo Island: a quieter white-sand strip north of Phi Phi Don, often included on speedboat day trips.
- Viewpoint hike: a 20–30 minute climb above Tonsai that gives you the classic twin-bay shot.
For snorkelling, the best spots around Phi Phi include the waters around Phi Phi Leh and Bamboo Island, where visibility is generally good outside the monsoon months. The reef fish are colourful and plentiful, though the coral has taken pressure from years of heavy visitor traffic.
Phi Phi’s nightlife is real and unapologetic. Tonsai Bay fills up after dark with fire dancers, beach bars, and live music. It suits backpackers and couples who want to combine a beach day with a social evening. Families with young children can still enjoy Phi Phi, particularly on quieter northern beaches, but the party strip is not easily avoided.
Travel from Phuket takes roughly 90 minutes by speedboat, or around 2 hours by ferry. From Krabi, the crossing is shorter at around 45 minutes by speedboat. Rough seas between May and October can cause cancellations, so book with an operator that offers flexible rescheduling.
Pro Tip: Book an early-departure speedboat tour to reach Maya Bay before 10 AM. The cove is noticeably quieter in the first hour, and the light is better for photos.
What to expect on the Similan Islands
The Similan Islands are a national park archipelago (Mu Ko Similan) sitting roughly 70 km off the Phang Nga coast. There are no resorts on the islands themselves, no nightlife, and no permanent population. What you get instead is some of the most biodiverse marine habitat in Southeast Asia.
The park records over 500 fish species and more than 200 coral species, and the dive sites range from gentle slopes for beginners to deep walls and pinnacles where manta rays and occasional whale sharks appear. Sail Rock (near Island No. 8) is one of the most celebrated dive sites in the region. Island No. 4 has a famous boulder formation called Donald Duck Rock, and the white-sand beaches on several islands are genuinely pristine.
Core highlights:
- Sail Rock / Island No. 8: top-tier scuba site with strong currents, pelagic fish, and dramatic underwater topography.
- Donald Duck Rock (Island No. 4): a recognisable granite formation above and below the waterline.
- White-sand beaches: several islands have beaches that see almost no foot traffic outside tour groups.
- Manta rays and whale sharks: seasonal sightings, more likely November through March.
- Short hikes and viewpoints: a handful of marked trails on certain islands give elevated views over the Andaman Sea.
Travellers consistently describe Similan as far less developed and more pristine than Phi Phi. The remote feel is a feature, not a flaw, for the right traveller. Day trips depart mainly from Khao Lak, which sits about 80 km north of Phuket. Liveaboards depart from Khao Lak and typically run 2–6 nights, giving divers access to multiple sites and the chance to reach deeper, less-visited spots.
The park closes every year from May through October. Plan your trip between November and April.
Pro Tip: Book your Similan liveaboard at least 2–3 months ahead for the November–January peak window. Berths on reputable vessels sell out quickly, and last-minute availability is rare for the better boats.
How to choose the right island for your trip
The honest answer is that this decision comes down to four questions.
Ask yourself:
- Do you scuba dive or want to learn? If yes, Similan is the priority.
- Do you dislike crowds and prefer quiet, undeveloped settings? Similan again.
- Are you travelling with children, first-time snorkellers, or people who want beach time and evening options? Phi Phi is the better fit.
- Are you visiting between May and October? Similan is closed. Phi Phi is your only option.
Decision flow by traveller type:
- Committed diver (certified, 3+ days available, November–April): Go Similan, ideally on a liveaboard.
- Casual snorkeller or beach-lover (any season, 1 day available): Go Phi Phi — the snorkelling is good, the logistics are simple, and you can be back in Phuket for dinner.
- Couple wanting romance and quiet beaches (November–April): Similan for the day, Phi Phi for the overnight stay. They complement each other well across two days.
- Backpacker or solo traveller on a budget: Phi Phi, where shared speedboat tours start from around 1,500 Baht and accommodation on Phi Phi Don is plentiful.
- Family with young children: Phi Phi, where calmer bays and shorter transfers reduce the stress.
- Photographer or wildlife enthusiast (November–April): Similan for underwater shots; Phi Phi for landscapes and the viewpoint.
On combining both: operators advise against putting Phi Phi and Similan into a single day. They sit in opposite directions from Phuket, and the combined boat time leaves you exhausted with little time at either place. If you have two days, split them: one per destination.
Getting there: travel times, costs, and the Similan closure
Launch points and travel times
Getting to Phi Phi from Phuket takes roughly 90 minutes by speedboat or around 2 hours by ferry. From Krabi, a speedboat covers the distance in about 45 minutes. Phuket’s Rassada Pier and Ao Nang in Krabi are the main departure points.
Similan is a longer journey. Most day trips and liveaboards depart from Tab Lamu Pier in Khao Lak, which is about 80 km north of Phuket. The drive from Phuket to Khao Lak takes roughly 1.5 hours, followed by a 60–90 minute speedboat crossing to the islands. Factor in an early start: most Similan day trips leave the pier before 8 AM.
Typical costs
Day-trip prices vary by vessel type. Speedboat tours generally run from around 1,500–4,000 Baht per person for a shared group trip, with private charters sitting considerably higher. Ferry crossings to Phi Phi are cheaper but slower. Similan day trips cost more than Phi Phi equivalents once you factor in the national park entrance fee, longer fuel costs, and equipment hire.
Liveaboards are the biggest cost variable for Similan. A 2–3 night diving liveaboard from Khao Lak typically runs several times the price of a Phi Phi day trip, and that gap widens for premium vessels with smaller groups and more dive sites.
| Trip type | Destination | Typical price range (per person) | Duration |
|---|---|---|---|
| Shared speedboat day trip | Phi Phi | 1,500–4,000 Baht | 1 day |
| Ferry day trip | Phi Phi | 1,500–4,000 Baht | 1 day |
| Shared speedboat day trip | Similan | Higher than Phi Phi equivalent | 1 day |
| Liveaboard (2–3 nights) | Similan | Significantly higher | 2–3 nights |
Seasonality and the Similan closure
The Similan Islands national park closes every year from May through the end of October. The closure allows the marine ecosystem to recover from visitor pressure. Exact opening dates can shift slightly depending on park authority decisions, so check current notices before booking.
Phi Phi operates year-round, but the monsoon months (roughly May–October) bring rougher seas and a real risk of tour cancellations. If you are visiting in this window, book with an operator that offers free rescheduling and check conditions 48 hours before departure.
Pro Tip: Travelling in November? Both islands are open, the seas have calmed, and crowds have not yet peaked. It is one of the best windows to visit either destination.

A day trip works fine for casual snorkellers at either destination; for understanding the different tour types and planning, see our Great Barrier Reef Tour Comparison: Outer vs Inner vs Island. Serious divers, though, will find a Similan day trip rushed. The liveaboard format gives you more sites, better conditions at dawn and dusk, and none of the race-back-to-the-pier pressure.
Sea conditions, safety, and conservation rules
Safety on the water
Rough seas are the main risk on both routes, particularly between May and October. Speedboats in choppy conditions can be uncomfortable and occasionally dangerous. Choose a licensed operator, confirm that lifejackets are provided and worn during crossings, and take seasickness tablets the night before if you are prone to motion sickness. Reputable operators will cancel or reschedule when conditions are unsafe — if an operator is pushing ahead in clearly rough weather, that is a warning sign.
Scuba diving in the Similans requires a valid open-water certification at minimum. Some advanced sites require higher certification levels. Always dive with a guide who knows the local currents.
Environmental rules and conservation
The Similan Islands park closure (May–October) is the most significant conservation measure in place. During the open season, rules include:
- No touching or standing on coral.
- No anchoring on reefs (reputable operators use mooring buoys).
- No feeding fish or collecting marine life.
- No single-use plastics on the islands.
Maya Bay on Phi Phi Leh has its own access restrictions following a multi-year closure that allowed the coral to begin recovering. Visitor numbers are capped, and swimming in certain zones is restricted. These rules exist because the bay’s ecosystem was severely damaged during its peak tourism years.
Pro Tip: When choosing a Similan operator, ask directly whether they use mooring buoys at dive sites. Operators who anchor on reefs are not following park rules, and the damage is cumulative. A good operator will answer this question without hesitation.
Safety checklist:
- Reef-safe sunscreen (standard sunscreen is banned at many protected sites).
- Rash guard or wetsuit for snorkelling (sun protection and jellyfish).
- Dry bag for electronics.
- Dive certification card if you plan to scuba dive.
- Travel insurance that covers water sports.
What Phuket operators actually see and recommend
Operators running tours from Phuket and Khao Lak see a consistent pattern: travellers who book Phi Phi expecting a quiet, remote experience are often surprised by the crowds, while travellers who book Similan without realising the logistics involved sometimes find the early starts and longer transfers more demanding than expected.
The most common piece of advice from experienced local guides is to match your choice to your primary activity, not to a photo you saw online. Phi Phi looks stunning in pictures, but on a busy day in high season, Maya Bay has a queue. Similan looks remote in pictures, and it genuinely is — but getting there requires commitment.
Group tours are fine for both destinations, but private charters make a meaningful difference on Phi Phi, where a smaller boat means fewer stops at the busiest spots and more flexibility on timing. For Similan, the liveaboard versus day-trip question matters more than private versus group: a day trip gives you a taste, but a liveaboard gives you the destination.
Operators also handle cancellations differently. The best ones offer free rescheduling with 24–48 hours’ notice when weather is the cause. Always confirm the cancellation policy before paying.
Pro Tip: Book Phi Phi tours for Tuesday to Thursday if your schedule allows. Weekend departures from Phuket carry noticeably more passengers on shared boats, and the popular bays are busier as a result.
A local perspective on choosing between the two
When someone asks which island to pick, the answer I always come back to is: what are you actually going to do when you get there? Phi Phi is one of those places that delivers exactly what it promises — beautiful water, a social atmosphere, and enough variety to fill a full day or two nights comfortably. It is repeatable, too. Many travellers visit more than once and find something different each time, whether that is a quieter beach on the northern end of Phi Phi Don or a sunrise kayak before the day-trippers arrive.
Similan is a different kind of trip. The underwater world there is genuinely exceptional, and the beaches are among the cleanest in Thailand. But it rewards preparation. Go in the right season, book the right operator, and give it enough time — and it will be the highlight of a Thailand trip. Rush it or arrive in the wrong month, and you will miss what makes it special entirely.
The core decision rule is simple: match your activity and your available season to the island, not the other way around.
