Snorkel marathon

The best part of the Snorkel Marathon is simple: you get three chances to see Bonaire’s underwater world, not just one rushed stop. The boat ride adds fine city views, drinks, and time to enjoy the water between sites. Guides including Jermaine and Germaine are also a real asset, sharing local stories and adjusting the outing when wind or water conditions change.

I like the small-group limit of 15, especially since some outings have had only two or three couples aboard. I also like the nearly three-hour format, which gives you time to settle into the water instead of racing through a single reef. The catch is the boat transfer: you must climb into a small dinghy from the dock, then use a ladder to board the larger boat. That is a serious point for anyone with limited mobility.

Key points to know before booking

Snorkel marathon - Key points to know before booking

  • Three snorkel stops: Each stop is planned for about 50 minutes, with Klein Bonaire often the favorite.
  • Small groups: The maximum is 15 people, though some departures have been much smaller.
  • Dinghy transfer required: You board the main boat from a small rubber dinghy, then climb a ladder.
  • Pickup is included: Hotel pickup is offered, and cruise passengers can be collected near the port gate.
  • Gear and drinks included: Snorkel equipment, alcoholic beverages, private transportation, shade, and an onboard toilet are provided.
  • Good value at $75: The price covers a half-day boat outing with three water stops, rather than a single short swim.

Three Bonaire snorkel sites in one half-day

Snorkel marathon - Three Bonaire snorkel sites in one half-day

This outing is built around variety. You leave from Kralendijk, ride out by boat, and stop at three different places for roughly 50 minutes each. That structure matters because water conditions and marine life can vary from one location to the next.

At one site, you may find calmer water and easy fish watching. At another, the water may be deeper, with coral formations and larger open-water views. Klein Bonaire is often the high point, and some outings include a drift snorkel there. One account describes about 30 minutes in the water at Klein Bonaire, while the general schedule allows about 50 minutes per stop, so the exact time may depend on conditions and the day’s route.

The crew has taken groups to different sites when wind made the original plan less suitable. That flexibility is useful in Bonaire, where a sheltered stop can make a much better swim than a fixed route on a rough day.

You should keep expectations sensible. Many people have seen turtles, dolphins, colorful fish, coral, and a broad range of sea life. Others have found one stop less impressive than the others, or had a day when fish were less plentiful. Three locations improve your odds, but nature does not perform on a timetable.

The boat ride adds more than transportation

Snorkel marathon - The boat ride adds more than transportation

The ride between stops is part of the outing, not just dead time. You can sit in the shade, have a drink, and look back toward Kralendijk from the water. The city views give the day a pleasant rhythm: swim, climb aboard, dry off, watch the coast, then prepare for the next site.

The boat is described as a comfortable sport-fishing style vessel or small yacht, rather than a large sightseeing boat. That fits the small-group idea and gives the crew more room to respond to the day’s conditions. You are not being moved through a large, fixed program with a crowd of strangers.

An onboard toilet is available, and shade is provided. Life vests are available for anyone who wants one. These details may sound minor, but they make a difference during a three-hour outing, especially if you are not used to spending that long on a boat.

Alcoholic drinks are included. Snacks have also been provided on outings, though the listed inclusions specifically guarantee drinks and snorkel gear rather than breakfast. If you need a full meal before swimming, eat beforehand. Breakfast is not included, and towels are not supplied.

The dinghy transfer is the main practical concern

You do not simply walk from the dock onto the main boat. The outing begins with a transfer by small dinghy, and you must climb down from the pier, ride a short distance, and then get onto the larger vessel. At the end, you repeat the process in reverse.

Once aboard, you also use a ladder to enter and leave the water. The crew assists and has helped people who needed extra care, including someone recovering from surgery. Still, assistance does not remove the physical demands of the transfer.

I would not book this if you have a walking condition, poor balance, or serious difficulty climbing ladders. The operator specifically says it is not recommended for people with walking conditions. If you are in your 50s or older and reasonably mobile, the transfer may be manageable, but you should be honest about your strength and agility.

Wear something that lets you move freely. Keep your hands available for the ladder and follow the crew’s instructions. The crew has been praised for patience and help, but you should not treat this as a step-free boat tour.

A small crew can make the snorkel feel personal

The maximum group size is 15, and the actual number can be much lower. Some departures have had only six people, one other couple, or even a single booking party. That can make a large difference in the water.

With fewer people, you are less likely to spend the whole stop waiting for a crowd to enter or leave. The guides can keep an eye on the group, offer help with equipment, and spend more time pointing out sea life or explaining Bonaire.

The named guides vary by departure. Jermaine and Germaine receive especially warm praise, while other outings identify Rich, Larry, Jordy, or the captain and assistant by name. The consistent theme is local service, practical help, and a friendly approach. Some guides are lifelong residents, giving the ride an island perspective as well as a snorkeling focus.

Do remember that a small-group cap is not a promise of a private boat. Up to 15 people can book, and partner bookings may affect the final group. If privacy matters greatly to you, ask about the expected group size before you go.

What makes Klein Bonaire special

Snorkel marathon - What makes Klein Bonaire special

Klein Bonaire is the stop most often singled out as a favorite. Its clear water, coral, fish, and open setting can make it feel more rewarding than a quick swim close to town. One outing included a drift snorkel there, allowing the current to carry the group while the crew managed the boat position.

The word drift is important here. You are not necessarily swimming a straight out-and-back route. Conditions, mooring availability, wind, and the captain’s judgment shape how the stop works.

A warning is worth noting: one delayed departure reached the preferred area after the moorings were already full. The group had to change its timing and missed the most anticipated stop in the ideal way. That appears to be an exception rather than the normal plan, but it shows why an early pickup and prompt departure matter, especially for cruise passengers with limited time ashore.

The crew has also changed sites when needed. That is better than forcing a poor stop in rough water, but it means you should see the schedule as a plan rather than a guarantee.

Pickup works well for hotels and cruise stops

Snorkel marathon - Pickup works well for hotels and cruise stops

Roundtrip transportation is included. Hotel pickup is offered, and cruise passengers have been collected just outside the port gate before a short drive to the dock. The transfer from the cruise area to the boat has been described as about five minutes, and the dock may be walkable for some people, though arranged pickup is easier.

For a cruise visit, the 3-hour-15-minute duration fits a half-day ashore, but you must allow time around the tour. Do not schedule a tight shore-side activity immediately after returning. The dinghy transfer, equipment handling, and drive back to your pickup point all require a little breathing room.

The stated pickup arrangement can vary by location, so confirm the meeting point when booking. A mobile ticket is accepted, and confirmation normally arrives at booking. Reservations made within 16 hours of departure are confirmed as soon as possible, subject to availability.

The tour runs in the morning or afternoon. Morning may suit you if you want more time afterward in Kralendijk. Afternoon can work well if you prefer a slower start, but your exact water conditions will depend on the day.

Is $75 a fair price?

Snorkel marathon - Is $75 a fair price?

At $75 per person, this is a solid value if you want a proper boat outing rather than a short shore swim. The fee includes private transportation, snorkel gear, alcoholic drinks, and three scheduled stops. You also get shade, an onboard toilet, and a small-group format.

The price looks even better when the boat carries only a handful of people. You may receive nearly private attention without paying a private charter rate. That is not guaranteed, but the group cap gives you a better chance than a large excursion boat.

The value is less clear if you are mainly interested in one famous site and do not enjoy boat time. You could spend part of the 3 hours and 15 minutes traveling between stops, waiting for the group, and managing the ladder. The three-stop plan is the reason to book, not simply the promise of one perfect reef.

You also need to budget for anything not supplied. Towels and breakfast are excluded. The listed drinks include alcoholic beverages, while food details can vary, so arrive fed and bring what you need for personal comfort, provided it fits the operator’s rules.

Who should book the Snorkel Marathon?

Snorkel marathon - Who should book the Snorkel Marathon?

I would recommend this outing to a confident swimmer who wants several chances to see fish and coral around Bonaire. It suits couples, families with older children, cruise passengers, and small groups that prefer local guides over a packed excursion.

It is especially appealing if you value time in the water. Three stops give you a better sample of the coast than a one-site trip, and the nearly 50-minute periods leave room to look around without racing.

The experience is less suitable for anyone who needs a flat, easy boarding process. The dinghy and ladder are not small details. If you have limited mobility, a recent injury, or discomfort in deep water, choose an outing with easier access.

I would also avoid booking it as your only Bonaire plan if missing a specific site would ruin your day. Wind, mooring availability, group timing, and sea conditions can change the route. The crew appears willing to adjust, but adjustment can mean giving up a preferred stop.

Cancellation and weather notes

You can cancel for a full refund up to 24 hours before the start time. Changes or cancellations inside that window are not accepted for a refund.

The outing requires suitable weather. If poor weather forces cancellation, you are offered another date or a full refund. The same applies if the minimum number of bookings is not reached.

That policy makes an early booking reasonable if your schedule is flexible, but keep the 24-hour cutoff in mind. If you are arriving by cruise and your port call is uncertain, read the timing carefully before paying.

Should you book it?

Book the Snorkel Marathon if you want three water stops, a local crew, and a small boat at a reasonable price. Klein Bonaire, the relaxed pace, and the chance of a very small group are the strongest reasons to choose it.

Skip it if climbing from a dinghy and using a boat ladder sounds unsafe or exhausting. Also think twice if you need a guaranteed visit to one exact site. For an able-bodied snorkeler who wants more than a single quick swim, this is a well-priced half-day outing with a good chance of seeing Bonaire’s coral, fish, turtles, and island views.
