The waters around Phi Phi in Thailand are home to colourful coral reefs, tropical fish and larger marine species, making the islands a natural playground for anyone curious about what lies beneath the surface. But should you stay close to the surface with a snorkel or head deeper with scuba gear? The answer depends on your confidence in the water, experience level and what you hope to see. Comparing the two can help you choose the right experience or plan to enjoy both during your stay.
Overview
When it comes to experiencing the marine world in this part of Thailand, snorkelling, island hopping and scuba diving around Phi Phi are not to be missed. Snorkelling is easy to pick up and works well for travellers who want a relaxed introduction to the reefs, particularly around sheltered bays and shallower waters. Scuba diving takes you further below the surface, opening access to deeper reefs, wrecks and specialised dive sites. Both can reveal colourful coral and fascinating marine life, but the experience, preparation and level of commitment are quite different.

Ideal Locations
Phi Phi’s surrounding waters offer excellent opportunities for both activities, although the locations you choose can shape the experience. For snorkelling, Pi Leh Bay and Loh Samah Bay are popular stops, with clear waters and easy opportunities to explore the underwater scenery. Resorts on Phi Phi Don, such as SAii Phi Phi Island Village, can arrange boat excursions to these and other nearby bays, making it convenient to explore beyond the immediate shoreline. Such properties also offer access to popular dive sites such as Koh Bida, Phi Phi Leh, Shark Point and the King Cruiser Wreck, which provide a wider range of underwater environments. Some dive centres additionally arrange excursions to multiple sites, allowing certified divers to explore according to their experience level.
Activity Differences and Experience Needed
Snorkelling is generally the simpler option for travellers who want to explore marine life without extensive preparation. You should be comfortable swimming, but you typically don’t need prior snorkelling experience. Equipment such as masks, snorkels and fins can often be rented or provided by resorts and excursion operators, making it easy to join a trip during your holiday.
Scuba diving requires more preparation because you need appropriate training and certification. However, not being a certified diver doesn’t necessarily mean you have to miss out. Resorts with professional dive centres will offer introductory experiences as well as recognised training and certification programmes. Equipment can also usually be rented through the dive centre, reducing the need to travel with bulky gear.
Marine Life Diversity
Both snorkelling and diving can introduce you to Phi Phi’s colourful underwater ecosystem. Depending on the location and conditions, snorkellers may spot clownfish sheltering among sea anemones, blacktip reef sharks, turtles and schools of tropical reef fish. The relationship between clownfish and sea anemones is particularly interesting to observe, as both species benefit from their close association.
Divers can encounter similar marine life while also exploring deeper sections of reefs where additional species and underwater habitats may be found. Around the wider Andaman region, dive excursions can offer opportunities to encounter larger species such as bamboo sharks, whale sharks and other shark species.
Depth, Exploration and the Overall Experience
The biggest difference between the two activities is the underwater perspective they provide. Snorkelling keeps you close to the surface, making it ideal for taking in the colours of shallow reefs while still enjoying the surrounding scenery. It can also be easier to combine with island-hopping, swimming and beach visits in a single day.
Scuba diving allows you to descend further and spend more time exploring underwater environments. This makes it possible to investigate deeper reefs, underwater rock formations and wreck sites that aren’t accessible to snorkellers. For certified divers, sites such as the King Cruiser Wreck provide a very different type of experience from exploring a shallow tropical bay. The right choice ultimately depends on whether you prefer an easy-going introduction or a more immersive adventure.
Cost Comparisons
Snorkelling can be one of the more accessible ways to explore Phi Phi’s marine environment. If your resort provides equipment or you join an excursion where gear is included, there may be little additional cost beyond your accommodation. Private or full-day boat trips, however, will cost more.
Scuba diving costs vary considerably depending on whether you need introductory training, certification or guided dives. The following 2026 rates provide an indication of available dive experiences, but prices can change and should be confirmed directly with the dive centre or resort before booking.

Who Each Activity is Best For
Snorkelling is ideal for:
- Travellers who have little or no previous experience with underwater activities.
- Families who want an easy activity that can be combined with swimming and island excursions.
- Couples who prefer a relaxed way to explore Phi Phi’s clear waters.
- Visitors who want to spend a short amount of time in the water without committing to a full dive experience.
- Travellers who enjoy shallow reefs, colourful fish and the flexibility to move between different bays and beaches.
Scuba Diving is ideal for:
- Certified divers who want to explore Phi Phi’s deeper underwater environments.
- Travellers interested in wrecks, deeper reefs and more immersive marine encounters.
- Those willing to complete introductory training or certification during their holiday.
- Experienced divers looking to explore established sites around Phi Phi and the wider Andaman Sea.
- Travellers who want to spend more dedicated time underwater rather than combining marine exploration with a broader island-hopping itinerary.
For travellers staying at a resort on Phi Phi Don with access to a dive centre, it can be particularly convenient to experience both. You could begin with snorkelling around the islands’ scenic bays and then progress to a guided dive if you discover that you want to explore further below the surface. Pro tip: Look to stay at a resort that not only offers these activities but also has a marine discovery centre, allowing guests to learn more about the local ecosystem while enjoying the surrounding waters.
Conclusion
Snorkelling and scuba diving each reveal a different side of Phi Phi’s marine beauty. Snorkelling offers an accessible way to enjoy colourful reefs and tropical marine life, while scuba diving opens up deeper environments, specialised dive sites and a more immersive underwater experience. Rather than choosing one over the other, travellers with enough time can combine both. Doing so gives you the best opportunity to appreciate the full range of marine life and underwater landscapes around Phi Phi.
