Dominica Sperm Whale Delirium 🇩🇲
Up Close with Ocean Giants
- Round 2 -
If you like the following, this trip might be for you:
Whale Delirium
The "Group of Seven", the best-studied pod of sperm whales in the world. They have roamed the coast of Dominica since 2005 and are one of the most famous pods, in particular for their tolerance to divers when being approached in a calm and considerate way. Dives take places after the whales are located by underwater listening devices! 🔈
Small Group Travel 🛥️
A group of only 6 divers goes out to venture for whales. This is one of the smallest groups of any dive trip we have to offer to any destination! A unique chance to get that one epic eye to eye shot with a whale, undisturbed by other dive groups! Important to note that this trip is a snorkelling and free diving trip only, so don't expect any scuba diving activity.
Stellar Accomodation
Located in the idyllic Soufriere Valley, Soufriere Guesthouse is the perfect place to stay and dive Dominica in a unique community setting. We come back here to relax from a day at sea, overlooking a garden in tranquility. A short walk into town as well, making it a perfect "base". 🌱
Cetaceans Dream 🌋
Laying embedded in the Caribbean, Dominica is surrounded by sheltered bays and deep underwater canyons. This environment provides shelter for a range of cetacean species in addition to sperm whales, such as common and bottlenose dolphins and humpback whales! Anything can happen here, you just need to be there!
Green Fertility 🌿
Formed from volcanic activity, the island's soil is incredibly fertile. Flowers and plants flourish around the island, making it a wondrous place not only for ocean lovers, but also for on land nature enthusiasts. We had a blast hiking and discovering the jungles here! 🌴
Authentic Travel 🇩🇲
As of yet, Dominica does not have the huge touristic influx that heavily impacted other places in the Caribbean. This means that big parts of the island still have their local atmosphere and really feel "different". We love this authenticity and we are sure you will too!
What Marcel Thinks
"Dominica is an absolute peach of an island: green, relaxed and full of marine life. The whale encounters are fairly spectacular: nowhere you can get up this close in such small dive groups. Regulations are also fiercely enforced animal disturbance is minimal. The local crew is also a true joy to hang out with. I would go back in a heartbeat."

Soufrière Guest House
Soufriere Guesthouse sits in the lush Soufriere Valley on Dominica’s southwest coast, surrounded by forest and within easy walking distance of natural hot and cold springs. The Soufriere-Scott’s Head Marine Reserve and Scotts Head Beach are close by, and Roseau is only around 8 km away, making it a genuinely convenient base without sacrificing the feeling of being off the beaten track.
Accommodation runs to five private en-suite rooms and two dormitory options, all with WiFi and hot water. Rooms include rainfall showerheads, and some have a patio with mountain views and their own kitchen setup. There is no air conditioning, something worth knowing before you book, but fans are provided and the valley setting keeps things cooler than the coast.
The communal spaces are a strong suit, with a well-equipped shared kitchen, a hammock-lined balcony, and yoga equipment available to guests. Reviews are consistently warm, with guests praising the cleanliness, spacious feel, and the hosts’ local knowledge. For the price, it punches well above its weight.
Although around 20 different whale families have been identified in Dominica, 10 families are regularly spotted since 1984. Sperm whales live up to 70 years and is believed that they encounter and interact with other whales on a regular basis, which means that they can remember each other over long periods of time.
According to scientists, these interactions are possible through a complex set of dialects of clicking sounds, often called ‘codas’. Although each unit has its own set of clicks, there does seem to be overlaps between these codas of different units. Fascinatingly, units who share similarities in sound repertoires tend to spend time together, while those with different repertoires never seem to do so.
One of the coda types frequently recognised amongst the Caribbean units is the ‘1 + 1 + 3’, which comprises of two short clicks separated by a pause, followed by three clicks in a row. For over three decades this sequence has been documented in the area.
The whale pods are located by underwater listening devices. When located, we gently approach and three people can slide into the water with the whales without disturbing their activities. Interactions can last 30 seconds or 15 minutes: that is up to the whales and how they behave. If an interaction lasts over a certain amount of minutes, the three people in the water will make way for three other guests on the boat. After that we rotate to ensure that all guests get a similar amount of time in the water with these ocean giants. In case of a short encounter, the next approach will be done by the three following guests in line.
Although there is no guarantee on the interaction time, days without any whale sightings are extremely rare. We often encounter other cetaceans in search of sperm whales and there will be lots of other marine life around to admire. As the action evolves several miles out to sea, and always in different spots, guests should be aware that this trip involves plenty of boat time searching and waiting for the right rewarding encounter. Looking out for action on the water, and swimming in order to approach the animals, will form part of this adventure.
Packed lunches, water, tea and coffee are provided on the boat. The water temperatures are around the low 20s C., so most guests are comfortable in a 3mm wetsuit.
