Best Boat Trips from Koh Samui: Pig Island, Koh Tan & Island Hopping

2. Private longtail boat to Pig Island and Koh Tan

See the private Koh Tan and Pig Island longtail itinerary for the current boat capacity and available departures.

Best for flexibility

A private longtail is one of the most attractive ways to do the Pig Island route.

Instead of joining a fixed group schedule, you hire the boat for your own party.

Depending on the operator, that can give you more control over:

• departure time;
• time at Koh Tan;
• time on Pig Island;
• lunch;
• snorkeling;
• pace.

The traditional Thai longtail also makes the journey itself feel more distinctive.

Who should book private?

Private makes most sense for:

• families;
• groups of friends;
• couples who value privacy;
• travellers celebrating something;
• anyone who dislikes large tour groups.

If you are travelling with four or more people, always compare the total charter price with the combined cost of shared tickets.

The difference can be smaller than expected.

3. Ang Thong Marine Park boat trip

Compare Ang Thong snorkeling and kayaking from Samui. Review the departure, inclusions and conditions for your date.

Best for scenery

Mu Ko Ang Thong National Marine Park is the major scenery-focused boat excursion from Koh Samui.

The park contains dozens of islands with:

• limestone cliffs;
• lagoons;
• beaches;
• viewpoints;
• kayaking routes.

This is a much bigger-feeling trip than Pig Island.

A typical day includes:

• longer boat journey;
• kayaking;
• viewpoint walk;
• beach stop;
• lunch;
• swimming;
• sometimes snorkeling.

Who should choose Ang Thong?

Choose Ang Thong if you:

• want dramatic landscapes;
• enjoy kayaking;
• do not mind a full-day trip;
• want a bigger adventure;
• are comfortable spending longer on a boat.

Important seasonal point

Mu Ko Ang Thong has a seasonal tourism closure. The Tourism Authority of Thailand’s published 2024 schedule ran from 1 November to 15 December; confirm the current year’s dates with the park or operator before booking November or December. See the official published schedule.

If you are visiting Koh Samui around that period, check current park access before booking.

4. Koh Tao + Koh Nang Yuan boat trip

Compare Koh Tao and Koh Nang Yuan from Samui. Review the departure, inclusions and conditions for your date.

Best for snorkeling

If snorkeling is the main reason you want a boat trip, Koh Tao is the stronger full-day option.

Koh Tao is well known for diving and snorkeling, while Koh Nang Yuan is famous for its sandbar and viewpoint.

Compared with Pig Island, expect:

• earlier start;
• longer travel;
• more time on a fast boat;
• a full-day schedule;
• stronger emphasis on underwater activity.

Who should choose Koh Tao?

Choose Koh Tao if:

• snorkeling is your main priority;
• you are comfortable on fast boats;
• you want a full marine day;
• you do not mind a longer journey.

If you only want one easy snorkeling stop plus a beach experience, Koh Tan is more convenient.

5. Private speedboat charter

This private Pig Island and snorkeling speedboat trip is a south-coast option. It does not imply that Koh Tao or Ang Thong is included; agree any longer route and its price separately.

Best for groups who want to cover more ground

A private speedboat costs more than a shared ticket, but it can be useful if your group wants a customised day.

Possible itineraries may include:

• Pig Island;
• Koh Tan;
• southern beaches;
• snorkeling;
• lunch;
• sunset;
• additional island stops.

The main advantage is speed.

Compared with a longtail, a speedboat lets you cover more distance in less time.

Who should choose a speedboat?

Choose private speedboat if:

• your group wants flexibility;
• you want faster transfers;
• you have a larger budget;
• you want to combine more stops.

For a simple Pig Island + Koh Tan trip, a longtail is often enough.

Longtail boat vs speedboat

This is one of the most common decisions.

Longtail boat

Best for:

• atmosphere;
• private groups;
• short southern routes;
• slower pace;
• traditional experience.

Advantages:

• classic Thai style;
• excellent for photography;
• often used for private charters;
• perfectly suitable for Koh Tan and Pig Island.

Downsides:

• noisier;
• more exposed;
• can feel bumpier;
• slower.

Speedboat

Best for:

• faster transfers;
• longer routes;
• shared tours;
• travellers who want efficiency.

Advantages:

• quick;
• practical;
• better for longer distances.

Downsides:

• ride can still be rough;
• often larger group;
• less atmospheric than a longtail.

For Pig Island, speed is less important because the route is already short.

Shared tour vs private boat

Shared tour

Shared trips are usually best for:

• solo travellers;
• couples;
• budget-conscious visitors;
• people who want everything organised.

They commonly include:

• transfers;
• guide;
• snorkeling gear;
• boat;
• lunch or drinks.

The downside is a fixed schedule.

Private boat

Private boats are best for:

• families;
• groups;
• flexible timing;
• travellers who dislike crowds;
• special occasions.

You may pay more, but you control the boat and schedule.

Half-day vs full-day boat trip

This is one of the easiest ways to narrow your choice.

Half-day

Choose a half-day boat trip if:

• you have limited time;
• you are travelling with children;
• you want a simple excursion;
• you want to keep part of the day free;
• you do not love long boat rides.

Best option: Pig Island + Koh Tan

Full-day

Choose a full-day trip if:

• the boat trip is one of your holiday highlights;
• you want dramatic scenery;
• you want serious snorkeling;
• you do not mind a long day.

Best options: Ang Thong or Koh Tao

Morning vs afternoon boat trip

Morning departures are the easiest default for most travellers.

Advantages include:

• cooler temperatures;
• more of the day left afterward;
• lower risk of afternoon heat;
• often more predictable conditions.

Afternoon trips can still be attractive if:

• you dislike early starts;
• you want sunset;
• you want a slower holiday schedule.

For Pig Island, both morning and afternoon departures are available with some operators.

Sunset boat trips

Compare the itinerary on the Pig Island and Koh Tan sunset trip with dinner; sunset colours and snorkeling visibility depend on conditions.

Sunset trips are more about atmosphere than sightseeing intensity.

A sunset cruise can be a good choice for couples who want:

• slower pace;
• drinks or dinner;
• coastal views;
• late-afternoon light.

Some operators combine sunset with Pig Island or southern Koh Samui.

Others simply cruise along the coast.

Do not confuse a sunset cruise with a snorkeling-heavy itinerary.

They serve different purposes.

Which boat trip is best for families?

For most families:

Why?

• short crossing;
• half-day option;
• pigs;
• snorkeling;
• beach;
• less time sitting still.

A private longtail is especially attractive for families because you can adjust the pace.

Which boat trip is best for couples?

Couples have several good options.

Pig Island private longtail

Best for a relaxed half-day.

Sunset cruise

Best for atmosphere.

Ang Thong

Best for adventure.

Koh Tao

Best if you both love snorkeling.

Your choice should depend on what kind of day you want rather than which tour sounds most romantic in the title.

Which boat trip is best for older travellers?

This depends on mobility and comfort.

Consider:

• boarding style;
• toilet availability;
• shade;
• boat size;
• walking required;
• transfer length.

Pig Island is close, but longtail boarding can still be awkward.

Ang Thong often involves more walking and steep steps.

Koh Tao involves a long day on a fast boat.

Always check the exact physical demands.

Best boat trip if you get seasick

No boat is completely immune to motion.

But shorter journeys are usually easier.

That makes Pig Island + Koh Tan the most logical option.

You can also:

• sit near the centre of the boat;
• face forward;
• avoid heavy meals before departure;
• use your usual motion-sickness medication if appropriate for you.

If seasickness is severe, do not choose a long Koh Tao transfer simply because it has better snorkeling.

Best boat trip for snorkeling

Two clear options:

Easy snorkeling:

Koh Tan

Dedicated snorkeling:

Koh Tao

Koh Tan works because it is close.

Koh Tao is more focused.

If snorkeling is just one thing you want to do, choose Koh Tan.

If it is the entire point of the day, consider Koh Tao.

Best boat trip for scenery

This is the route to choose if the visual landscape matters most.

Pig Island is fun and photogenic.

Ang Thong is more dramatic.

Best boat trip for photography

This depends on your style.

Pig Island

Best for unusual travel photos.

Longtail boat

Best for classic Thai boat imagery.

Ang Thong

Best for landscapes.

Koh Nang Yuan

Best for sandbar and viewpoint images.

Sunset cruise

Best for golden-hour shots.

Best boat trip for a group

Private charter.

If you are travelling with five, six or more people, do the maths before booking shared seats.

A private longtail can sometimes offer better value once the group is large enough.

You also gain:

• privacy;
• flexible schedule;
• fewer strangers;
• easier family logistics.

How much should you pay?

Prices vary by:

• route;
• boat type;
• group size;
• inclusions;
• season;
• private vs shared;
• transfer zone;
• lunch;
• guide.

Do not compare tours purely by the headline price.

A cheaper option may exclude:

• hotel transfer;
• national park fee;
• snorkeling gear;
• lunch;
• island fee.

Always compare the total cost.

What should a good tour include?

At minimum, check for:

• clear itinerary;
• boat type;
• pickup details;
• snorkeling equipment;
• life jacket;
• insurance;
• guide;
• drinks;
• lunch if advertised;
• fees;
• cancellation policy.

A well-written listing should make these obvious.

What should you bring?

For most Koh Samui boat trips:

• swimwear;
• towel;
• sunscreen;
• hat;
• sunglasses;
• rash vest;
• dry bag;
• waterproof phone case;
• water;
• cash;
• change of clothes.

For full-day trips, also consider:

• light jacket;
• extra snacks;
• power bank.

What happens in bad weather?

Boat trips can be:

• delayed;
• rerouted;
• shortened;
• rescheduled;
• cancelled.

The deciding factor is not simply rain.

Wind and sea state are often more important.

A rainy but calm morning may still be usable.

A sunny but very windy day may not be.

Always follow the captain’s decision.

Best season for Koh Samui boat trips

For Pig Island and Koh Tan, the most reliable period is generally late January through April.

May through September can still be very workable.

October becomes more unsettled.

November is usually the most difficult month for sea conditions around Koh Samui.

Different routes may have additional seasonal constraints, such as marine park closures.
