Boat Tour to Johnny Cay & Aquarium in San Andres Island

Two bright Caribbean stops make this San Andrés boat trip appealing: Rocky Cay, sometimes called Johnny Cay in the tour title, and the shallow Aquarium, also known as Rose Cay. I like the easy five-hour plan, which gives you about two hours at Rocky Cay and three hours at the Aquarium without trying to cram the whole island into one morning.

I also like the small maximum group size of 10 people and the help available from qualified staff. Cecilia Forbes receives especially warm praise for her organization and personal attention. The main caution is important: the boat is simple, the ride can be wet, and the exact island plan can change with weather or local authorities.

Key things to know before booking

• The advertised island names need checking: The experience is sold as Johnny Cay and Aquarium, while the detailed route lists Cayo Rocoso, or Rocky Cay, and Cayo Acuario. Confirm the exact stops before booking.
• The Aquarium is the longer stop: You get about three hours in water close to one meter deep, with clear conditions suited to seeing fish from near shore.
• Bring water shoes: The Aquarium can be rocky, and walking barefoot may be uncomfortable or unsafe.
• Budget for extra charges: The price is $39.50 per person, but dock taxes of 15,000 COP per person are not included. Food, drinks and some equipment cost extra.
• Weather controls the day: Strong rain, wind or rough water can cancel or change the route. A different date or full refund is offered when poor weather cancels the activity.
• Expect transport more than guiding: You receive boat transport and an internal bay tour, but the island time is largely yours to enjoy at your own pace.

What the $39.50 price really buys

At $39.50 per person, this is a reasonably priced way to reach two of San Andrés Island’s best-known water stops. The value comes from having boat transportation arranged, a reserved place on the island excursion, staff assistance and a roughly five-hour outing.

That price is not the complete cost. You should add a 15,000 COP dock tax per person, plus another listed 15,000 COP charge for Rocky Key. The wording makes these fees look like separate charges, so I would confirm the total amount with the operator before the morning of the trip.

Food and drinks are not included. Snorkeling equipment may also involve an extra payment, and one important equipment problem has been reported: gear was offered, but the mouthpiece needed to use it was not available. I would bring your own mask and snorkel if you already have them.

The tour makes sense if you want a straightforward island outing rather than a private boat charter. It is less attractive if you expect a full guided marine lesson, premium transport or every cost to be covered in advance.

Starting at Muelle Portofino at 8:30 am

The meeting point is Muelle Portofino, at Cra. 1 #2304 in San Andrés. The stated start time is 8:30 am, and the activity ends back at the same meeting point after about five hours.

Allow time to find the pier and arrive early. Your confirmation is sent at booking, and the operator may contact you with guide and meeting instructions before departure. Keep those messages handy. One poor experience came from confusion about tickets and arrival information, so do not wait until the last minute to check where you need to go.

The boat includes an internal tour of the bay. That part gives you a useful look at San Andrés from the water, but you should set your expectations correctly. This is not presented as a long historical or ecological narration. It is primarily transportation between island stops, with staff available to help.

The maximum group size is 10 people, which should make boarding and general coordination easier than on a large excursion boat. Still, the boat itself may be basic. Several accounts describe it as small or uncomfortable, with seawater splashing passengers and soaking bags when the sea is rough.

Use a dry bag or sealable plastic pouch for phones, wallets and passports. Sunglasses and a hat are useful, but secure them well. Salt spray is not kind to electronics.

Rocky Cay, or the Johnny Cay question

The first listed stop is Cayo Rocoso, commonly written as Rocky Cay. The tour title refers to Johnny Cay, however, and several descriptions discuss Johnny Cay as the main island visit. Because those names are not interchangeable in the supplied details, I would ask the operator exactly which cay is included on your date.

The planned stay at Rocky Cay is about two hours. The appeal is simple: rock, sand, clear Caribbean water and time to rest without a packed schedule. This is the sort of stop where I would swim, sit in the shallows, take photographs and let the clock slow down.

Do not expect a long list of organized activities. The experience is mainly a beach and water outing. Food and drinks are not included, so plan to buy them separately if available or carry what the rules allow.

Johnny Cay can be closed by local authorities. One booking went ahead without that stop because officials had shut it, and another weather-affected plan replaced an island visit with the Aquarium and a mangrove area. This is not necessarily a failure by the operator. San Andrés boat trips depend on wind, rain, waves and official access decisions.

The practical lesson is to treat the named islands as weather-dependent highlights, not guaranteed scenery under every condition. If Johnny Cay is the main reason you are booking, ask about the current access status before departure.

The Aquarium, Rose Cay and shallow water

Cayo Acuario, also called Rose Cay, is the strongest part of the trip for many people. The water is described as close to one meter deep, creating the unusual feeling that you can walk far out while still standing.

The clear water makes this a good place for simple snorkeling. Fish may be visible from near the shore, and one particularly enthusiastic account described the visibility as good enough to see fish without swimming far from land.

That shallow water does not mean bare feet are a good idea. The bottom can be very rocky, and water shoes are one of the smartest things you can pack. They protect your feet while entering the water and make it easier to move around comfortably.

You may also see stingrays and small sharks in the area. The available advice describes the sharks as non-biting, but you should still follow staff instructions and give marine life space. Do not chase, touch or crowd animals simply because the water is shallow.

The planned stay is about three hours, longer than at Rocky Cay. That gives you time to swim, snorkel, eat something, dry off and enjoy the color of the sea without rushing back to the boat. The Aquarium is not a formal aquarium building. It is a shallow marine area where the water and fish are the attraction.

Conditions can affect the experience. With higher tides or stronger currents, crossing parts of the area may become difficult. One outing used a glass-bottom boat when walking across was not practical. That option is not promised in the tour details, so consider it an example of how the day may be adjusted rather than a guaranteed feature.

What the guide actually does

Cecilia Forbes is the name most closely connected with the strongest service comments. She has been praised for being attentive, organized and generous with practical advice about the trip and other places to visit on San Andrés.

The operator states that Cecilia speaks English, which may matter if you are booking an English-language experience. Still, guide assignment can vary, so I would confirm your language needs in advance rather than assume a particular person will lead your outing.

This is a good fit if you want someone to help with timing, meeting instructions, island arrangements and basic orientation. It is not the right choice if you want a guide beside you throughout every swim or a detailed lecture at each stop.

The distinction matters. The service includes qualified personnel and an internal bay tour, but the island hours are designed for independent relaxation. You will generally have time to set your own pace rather than follow a continuous guided program.

Boat comfort, boarding and sea conditions

The boat ride to the cays is part of the fun, but it is not luxury transport. Accounts describe a basic boat and occasional discomfort. When the sea is choppy, spray can hit your face, salt water can irritate your eyes and bags can get soaked.

Wear quick-drying clothes and avoid carrying anything that cannot handle water. A lightweight cover-up is more useful than formal beachwear. If you are prone to motion discomfort, consider taking your usual remedy before departure, though no specific motion-sickness service is included.

Boarding can also require care. On a rough-water day, getting off the boat may involve stepping or jumping into the water. That can be awkward when many people are leaving at once. Water shoes help, and you should wait for staff instructions instead of rushing.

The tour is best suited to people comfortable with a basic boat, wet conditions and changing sea behavior. Families can participate because most people can join, but parents should pay close attention during boarding and in the water. Anyone with mobility concerns should ask the operator about current boarding conditions before booking.

Weather can rewrite the route

San Andrés weather is the deciding factor on this outing. Rain and strong wind can prevent the boat from reaching Johnny Cay or another planned stop. In one carefully managed plan, the group visited the Aquarium and then went to a mangrove area after weather made the original route unsafe. A later attempt to reach Johnny Cay was also stopped by conditions.

That flexibility is sensible. The sea is not a sightseeing schedule, and safety should come before completing every advertised stop. You may be offered a replacement plan, a new date or a refund if poor weather cancels the tour.

The cancellation terms are favorable if your plans change: cancel at least 24 hours before the local start time for a full refund. Changes or cancellations inside that 24-hour window are not accepted for a refund. If the operator cancels because of poor weather, you are offered another date or a full refund.

I would avoid placing this excursion on the final morning of your holiday. A weather cancellation may leave no time to reschedule, especially when the tour is popular and commonly booked about 20 days ahead.

What to pack for a better day

A few small choices can make a large difference:

• Water shoes for the rocky Aquarium bottom and wet boarding
• Your own snorkeling equipment, if possible
• A waterproof pouch or dry bag for valuables
• Sunscreen, applied generously and reapplied during the long beach stops
• A towel and spare dry clothing
• Cash for dock taxes, food, drinks or optional purchases
• A hat and sunglasses that can handle wind and spray

Sunscreen deserves special attention. You can spend most of the day exposed on the beach or in shallow water, where the breeze makes the sun feel less intense than it is.

Do not count on the $39.50 fare to cover lunch, drinks, dock charges or snorkeling gear. Preparing for those extras keeps the day simple and prevents a small island trip from becoming an unexpectedly expensive one.

Who will enjoy this five-hour outing

I would recommend this tour to you if you want easy access to clear water, a half-day away from San Andrés town and plenty of time to swim or relax. It works especially well for couples, friends and solo visitors who are happy to enjoy the islands without constant narration.

It can also suit families, provided everyone is comfortable with a simple boat and careful water entry. The shallow Aquarium is appealing for people who want to see marine life without going far offshore.

I would hesitate to recommend it if you want a private experience, a large comfortable boat, a guaranteed Johnny Cay stop or a fully guided snorkeling lesson. The operator’s own response to one unhappy booking makes the product’s role clear: it guarantees a place on the island excursion, not a personalized tour.

That is a fair distinction, but it should be clear before you pay. You are buying access and transport, not a tailor-made day.

Final verdict: book it with the right expectations

I would book this boat tour if your priority is clear water, beach time and a simple route to the cays at a moderate starting price. The Aquarium is the main draw, and the combination of shallow water, fish and a three-hour stay gives you time to enjoy it properly.

Before booking, confirm whether your departure includes Rocky Cay, Johnny Cay or both. Ask about the 15,000 COP dock taxes, language support, snorkeling equipment and the current weather outlook. Bring water shoes, protect your bags and accept that the sea may change the plan.

For a relaxed half-day on San Andrés, this is a sensible choice. For luxury, detailed guiding or guaranteed island access, choose something more specialized.
