Scuba Diving in Mozambique with
Castelo do Mar



Snorkelling, sea safaris or merely relaxing on board will be welcome.

Shallow snorkelling off the Whaleboat wreck on the beach is perfect for the less experienced snorkeler.

Scuba diving Mozambique


Diving in Mozambique can be an extraordinary experience! Here you can tick off a bucket-list Marine Big 5! It’s well known that some of the best dive sports in the world are in Mozambique. Whilst Humpback Whale sightings are seasonal, Whale Sharks, Manta Rays, Turtles and Dolphins can be seen all year around.



Turtles – 5 of the world’s eight turtle species are found off the Inhamhane coast.

Manta Rays


Manta Rays – the Mozambique coastline from Barra up to Bazaruto is considered to be a hotspot.



Dolphins – quite common breaking the surface alongside boats, passing the front of the lodge in the Bay, or coming up playfully when diving or snorkeling.

Whale Sharks


Whale Sharks – after South America and Philippines, Mozambique ranks in the Top 5 destinations for diving with the biggest fish in the ocean.

Humpback Whales


Humpback Whales – migrate annually from Antarctica to the warm waters close to the equator where they give birth and breed and are normally seen from June to October (most likely in August).

It is great that you are coming for some diving! Our experienced staff will do their very best to ensure that your stay here will be great and unforgettable. In order to be able to do that, we have put together some general information for you to look through.



We are located in a malaria area. It is advised that you consult your doctor about what malaria prophylaxis to take. LARIUM / MEFLOQUINE / MEPHLIAM ARE NOT SAFE TO DIVE WITH. Other than that, it is a good idea to bring along a supply of mosquito repellent for prevention.

The small stuff


It’s not always the size that matters! What a lot of people don’t know is that we also have fantastic macro life in the shape of frogfish, nudibranchs, harlequin shrimps and other rare crustaceans, pipefish, leaf fish, dragon morays, ribbon eels, sea moths and much, much more!

The Big Stuff


This part of Mozambique is famous for its Megafauna – manta rays and whale sharks. The best chance to see mantas, in general, are on the deeper reefs where there are cleaning stations that the rays visit. By far the best chance to see whale sharks is actually not while scuba diving but on one of our ocean safaris. These majestic sharks tend to hang close to the surface where they feed and we go for a 2-hour boat trip with snorkel gear and swim with the whale sharks. On the Ocean Safaris, you also have the chance of seeing dolphins, mantas, turtles and in season (July – October) humpback whales.

Conservation Policy

Castelo Do Mar Scuba Diving (30)

We are always striving to dive with the minimum impact on our reefs and marine life. Because of this, we have a very strict, “Take only pictures, Leave only bubbles” policy and we don’t allow gloves as they tend to encourage people to touch corals and marine life.

General diving conditions

Castelo Do Mar Scuba Diving

The water temperature changes quite a lot throughout the year, from 19 degrees in July – August to 28 degrees in December – March. In April and October, it is usually around 24 degrees. Average visibility is ca 10-12 m. All our dives are done from 8,5M RIBs and we launch and beach through the surf zone. Since we do, at times can have fairly strong currents and because all our reefs are square profile (no wall diving), all our deeper dives are done with negative entries.

Certification requirements

As we are part of DAN Southern Africa’s safety partner program, we will only take you to the maximum depth allowed by your certification level. So if you are an Open Water diver and would like to visit our reefs that are deeper than 18m, you will need to complete the PADI Deep Adventure dive.This includes a little bit of studying to learn more about deep diving techniques, hazards, and procedures. An instructor will go through this with you in a short briefing. On the deep training dive, an instructor will be with you at all times and you will practice proper deep diving ascent and descent procedures and two staged skills.

This doesn’t take long and when it is done you carry on diving. This dive will be signed off on a training record. You may then continue deep diving with us with no additional training. It is also one of the mandatory dives required for PADI Advanced qualification, so you are on your way to the next level of certification. It is a PADI Standard that students have access to the PADI materials during and after the course, so you may find you need to purchase the PADI Adventures In Diving manual.

Not dived recently?

Castelo Do Mar Scuba Diving

As we are part of DAN Southern Africa’s safety partner program, if it has been more than a year since your last dive, we require that you complete a PADI refresher course. This includes a short theory session, a pool session where you refresh all your emergency and buoyancy skills and a dive. The PADI Medical statement needs to be completed for this program

PADI Medical Statement

Castelo Do Mar Scuba Diving

All students enrolling in any PADI course (including the refresher course) are required to complete this. All the different medical conditions that are affected by diving are listed. You need to read through each one, and if you find you can answer ‘YES’ to any question, then you will need to bring medical clearance signed by a doctor stating that you are ‘Fit to dive with no restrictions’ we are unable to begin any in-water training until signed clearance is received. It is very difficult and time-consuming to get this here in Inhambane, so it is a good idea to complete the form at home so as to avoid disappointment. Please note that the Medical Statement is not required for divers only doing fun dives and not enrolling in a course.
