Power 360 Sightseeing and Snorkel Cruise Antigua
Antigua looks different from the water. This six-hour power catamaran trip carries you past sea caves, beaches, historic harbors, and the dramatic Pillars of Hercules, then pauses for snorkeling and lunch before returning along the coast. It is part sightseeing tour, part beach break, and part open-water ride.
I like the full-island route, which gives you a broad sense of Antigua in one day, and I like the easy hotel pickup offered at selected resorts. Lunch, alcoholic drinks, and snorkeling gear are included, so the price covers more than a simple boat ride.
The main caution is the Atlantic crossing. It can be rough for about 20 minutes, and a full boat may leave you with limited seating or little room to move. If you get seasick or dislike a lively ride, this is not the safest bet.
Key points to know before booking

- Antigua from the water: You circle much of the island rather than visiting one beach and turning back.
- Two striking coastal sights: The boat passes the Pillars of Hercules and Devil’s Bridge, with time for sightseeing and photos.
- Snorkeling plus beach time: The reef stop may include a chance to snorkel or relax on shore, including Green Island on some outings.
- Lunch and open bar: A meal is served onboard, with drinks such as beer and Antiguan rum punch included.
- A lively boat ride: The Atlantic side can be rough, while the more sheltered coastal stretches are usually smoother.
- Large-capacity catamaran: The boat can carry up to 130 people, so comfort depends heavily on how full the departure is.
A six-hour circle around Antigua
This is one of the more ambitious boat outings from St. John’s. Rather than spending the day at one reef, you get a moving view of Antigua’s coast, with stops for major natural sights, snorkeling, food, and a look at English Harbour.
The boat is called the Excellence, and pickup commonly begins around 9:30 a.m. at selected hotels. Resort pickup and drop-off are valuable here because they remove the need to arrange a taxi to the marina. The tour duration is about six hours, not counting the ride from your hotel to the departure point.
I would think of this as a full half-day outing that can stretch into the afternoon. You are not simply being transported to a snorkeling site. You are committing to a substantial boat journey, and that is the heart of the experience.
The catamaran gives you several ways to spend the day. You can sit outside for the views, move inside if conditions allow, snorkel at the reef, relax on a beach, or stay onboard with a drink and watch the coast pass. The choice matters because not everyone in a group wants the same kind of day.

The Atlantic crossing is the tour’s big test

The first fast stretch can be rough. The open Atlantic has larger waves than the sheltered waters along Antigua’s western and southern coasts, and the crossing may feel like a short roller coaster ride.
The crew generally warns you when the sea is expected to get choppy. Still, practical preparation helps. Take motion-sickness medicine before departure if you need it, sit near the middle of the boat if you can, and keep a hand free for balance. The bow is the most exposed area, and spray can reach it.
This is also where the boat’s size matters. The listed maximum is 130 people, and accounts of different departures range from comfortable to very crowded. On a busy day, seats may be limited, especially when the boat first heads out and everyone wants an outside position.
I would not book this trip for someone with serious motion sickness, recent back surgery, or significant back problems. It is also not designed for people who need wheelchair access, and the stated fitness level is moderate. Children must be at least four years old, but the rough ride may still be tiring for young children.
Once the boat reaches calmer coastal water, the mood changes. The ride becomes easier, and you can focus on Antigua’s coves, beaches, homes, and landmarks. The contrast between the rough opening and the smoother second half is one reason the trip can feel demanding at first but relaxing later.
Pillars of Hercules: Antigua’s natural gateway

The boat cruises by the Pillars of Hercules, a notable rock formation near the entrance to English Harbour. The name refers to the tall limestone pillars rising from the water, and the site is best appreciated from the boat because you see the rocks framed by the sea.
You should have a camera ready before the boat reaches the formation. The stop is listed at about 30 minutes and includes cruising by and snorkeling. The water around this part of the coast is a useful introduction to the underwater portion of the day, though visibility and marine life can vary with weather and sea conditions.
The Pillars are also a good example of what this trip does well. You are not only swimming at a reef. You are connecting the snorkeling stop with the island’s larger coastal story, moving between rock formations, harbor entrances, beaches, and historic sites.
Do not expect a long guided walk or a land visit here. The attraction is viewed from the boat, and the time is shared between sightseeing and water activity.
Devil’s Bridge and the power of the eastern coast

Devil’s Bridge is Antigua’s most famous natural arch, carved by the sea along the rugged eastern shoreline. The boat cruises by for around 20 minutes, giving you a view of the rock bridge and the exposed Atlantic coast.
This side of Antigua feels very different from the calm postcard beaches. The water has more force, the shore is more open, and the rock formations show what years of waves can do. From the boat, you get the drama without having to walk over uneven ground.
The drawback is that this section can be harder to hear. Several people have found the spoken descriptions difficult to follow when sitting at the bow, especially with engine noise, wind, and music. If learning about the sights matters to you, try to sit where the onboard announcements are easiest to hear rather than choosing the most exposed seat.
The tour also points out coastal homes and landmarks along the way. The commentary can include famous houses, including Eric Clapton’s former home, though the quality of the narration depends on your position and the noise level onboard.

Snorkeling, Green Island, and time off the boat

The snorkeling stop is the day’s main activity away from the catamaran. You are fitted with equipment, enter the water at one of Antigua’s reef areas, and have time to look for coral and sea life.
The stop can be active rather than effortless. A large group may mean a line for masks and fins, and the water session can feel more like a workout than a quiet swim if many people enter at once. If you want a calm snorkeling experience with lots of time to inspect the reef, a smaller dedicated boat may suit you better.
If you are not keen on snorkeling, you are not left without options. The outing can include a beach stop at Green Island, where you may sit on shore with a beer or rum punch while others use the water. Some departures also include time at two beaches, but the exact shore time depends on the day’s route and sea conditions.
This flexibility makes the trip work well for mixed groups. One person can snorkel, another can swim, and someone else can simply enjoy the beach and scenery. Bring water shoes because the shoreline and seabed may be uncomfortable under bare feet.
The crew is expected to help with equipment and boarding. One particularly thoughtful touch described from the boat was a crew member named Ray bringing a conch shell to a passenger who was too seasick to snorkel. That does not change the rough-water issue, but it suggests that the staff can be attentive when someone needs help.
Lunch, rum punch, and the social side of the boat

Lunch is served onboard after the water activities. Food has included grilled chicken and fish with salad, and it is widely regarded as one of the stronger parts of the outing. The meal is practical rather than fancy, but a hot plate after swimming is exactly what most people need.
Alcoholic drinks are included, with beer and rum punch among the options. The Antiguan rum punch is part of the cruise’s relaxed holiday mood, but pace yourself. The sun, wind, motion, and alcohol can combine quickly, especially if you have already felt uneasy on the Atlantic crossing.
The boat can take on a party atmosphere, with music and a steady drink service. That suits you if you want a sociable day and do not mind noise. It may not suit you if you want quiet commentary or a peaceful reef trip.
Food allergies and dietary needs deserve attention before you board. At least one account raised concerns about limited choices for a restricted diet. Ask about ingredients when booking or before lunch rather than assuming a substitute will be available.
English Harbour adds history to the route

The cruise to historic English Harbour gives the sightseeing a useful change of pace. This sheltered harbor area is closely tied to Antigua’s naval past and is one of the island’s best-known cultural and coastal areas.
You see the harbor from the water rather than taking a full land tour of Nelson’s Dockyard. That means you get atmosphere and geography, not a detailed museum visit. If you have already planned a land excursion to English Harbour, this cruise will not replace it, but it offers a pleasant first look at the harbor’s position and surrounding coast.
For me, this is one of the trip’s most worthwhile features. A beach-only boat trip can blur together after a few hours. Passing English Harbour, Devil’s Bridge, the Pillars of Hercules, and the island’s beaches gives the day a stronger sense of place.
The onboard explanations are useful when you can hear them. Music, wind, and engine noise may compete with the guide, so listen closely when a landmark is announced and ask a crew member if you miss something.
Is $146.32 a fair price?

At $146.32 per person, this is not a cheap afternoon on the water. It is a fairer deal if you use the included parts: hotel pickup and drop-off at selected hotels, the six-hour boat trip, snorkeling, lunch, and alcoholic drinks.
A separate taxi, boat charter, snorkeling trip, meal, and drinks could quickly cost more. You are also paying for the chance to see a broad section of Antigua from the sea, which is difficult to duplicate on land in one half-day.
The value drops if you mainly want a quiet snorkeling session. A crowded boat, limited seating, noisy commentary, and a rough opening could make the cost feel high. The best value comes when you want variety: sightseeing, swimming, a beach pause, lunch, drinks, and a lively boat ride all in one booking.
The tour is usually booked about two weeks ahead. That is a useful planning guide, especially during busy resort periods, but availability and minimum numbers still apply.
What to pack and where to sit
Bring a swimsuit, towel, sunscreen, water shoes, a change of clothes, a camera, cash, and water. Keep valuables protected from spray, particularly during the Atlantic crossing.
If you are prone to motion sickness, take your usual remedy before the boat leaves. The tour is not recommended for people with motion sickness, and waiting until you feel ill may be too late.
Try to board early enough to choose a seat with some shelter and a clear view. The bow offers the strongest ride and the most spray. A more central position should be easier on your stomach, though seating can be tight on a full departure.
I would also bring a light cover-up. The Caribbean sun is strong, and six hours on the water can leave you more exposed than you expect. Cash is useful for any personal needs, even though the main meal and alcoholic drinks are included.
The experience is weather dependent. If poor weather forces a cancellation, you can receive another date or a full refund. The booking is otherwise non-refundable and cannot be changed for personal reasons, so check the forecast and your schedule before paying.
Who should book the Power 360 cruise?
I would choose this for a first visit to Antigua when you want to see the island from the water without arranging several separate activities. It suits couples, families with older children, and resort visitors who want a social day with food, drinks, scenery, and a short snorkeling session.
It is especially useful for a mixed group. Strong swimmers can snorkel, beach lovers can relax on shore, and sightseers can stay onboard for the coastal views. The included pickup also makes it simple for people staying at selected hotels.
I would skip it if you need a quiet, spacious boat, a highly detailed history tour, or a gentle ride from start to finish. People with back problems, recent back surgery, serious motion sickness, or mobility limitations should choose another activity.
