Dive Information at Thonga

Our resident Instructor is PADI trained and certified and offers a variety of courses to suit your individual requirements to get you breathing underwater and exploring the spectacular coral reefs at Thonga.

Diving at Thonga has been rated as some of the best in the world by seasoned divers. This coastline is typically verged by a continental shelf stretching for about three to five kilometres out to sea, before giving way to deeper, abyssal waters, but the shallow shelf immediately offshore is cut through by several canyon like reefs, relics of riverine erosion from a time when the ocean level was lower than it is today.

Diving is weather and tide dependent, as these affect boat launchings and at times can be cancelled at the last minute. Our PADI trained and certified instructors are passionate about the Indian Ocean and are able to share this infectious love of the sea by taking you to beyond the breakers and below the surface.

Thonga Home Reef – Gogos

Gogos is our most exciting and beautiful reef. Situated just beyond the backline, right in front of our lodge, makes the boat trip to this site less than 5 minutes!   The name Gogos means ‘Old Woman’ in Zulu and it refers to the old woman Angelfish that swim mid-water above the reef, playing with and biting diver’s bubbles.

Gogo’s depth ranges from 10 metres to a maximum of 18 metres and has a combination of a main, solid reef structure with rock and coral outcrops in impressive shapes and formations. Sand patches between the reefs often offer Ray sightings. As if the reef structure isn’t impressive enough, this reef offers a prolific array of fish, not only in numbers but also variety.  Then add other sea-life like turtles, shrimps, lobster, anenomies, tiger cowries and you can see why a good dive on Gogos is hard to beat.

There is also a resident potato bass who has surprised many of our divers by seeming to appear from nowhere to join in the fun!

3 Sisters

This reef offers spectacular big game and reef fish. It is situated a little further offshore, with an average depth of 16 metres and a maximum of 22 metres. On the northern side of the reef a small ledge starts developing into a wall as we move southwards. It’s a good idea to bring a dive torch along, as there are several deep caves and crevices where moray eels, different type of shrimp and other interesting sea-life are frequently spotted. Further south the wall fades to a steep slope and the sandy bottom is replaced by more reefs with plenty of interesting hiding places. A cloud of Yellow Banded Snapper usually hovers at the base of the slope.

Higher up the incline are more caves with anything from Lobster to Lionfish present.   On the south side the slope gradually fades out again to a flat reef.


A world of underwater entertainment … this very exciting reef offers spectacular coral, canyons and swim-throughs. Waterworld is situated only a couple of hundred metres from the shore and starts at a depth of 7 metres with a maximum depth of 14 metres. From the minute we roll over and descend down to the reef it feels like an amusement park. Swimming down the canyons, there is coral splashed out on the walls, which goes up and over into the next cove and canyon.

For the experienced diver, there are two swim-throughs, guarded by Chubs and Baardman.

This reef is absolutely covered in pristine coral. Because of the depth, this underwater playground seems to attract a lot of playful, juvenile fish of all species. Brightly coloured fusiliers often swim over in mid-water. Turtles are plentiful and can often be seen sleeping in caves or heading up to the surface for some fresh air. The sighting of a regal angel is also possible. However, this dive is more suitable to calm sea conditions.

Open Water Referrals

For those people who want to do the full open water certification course but who do not want to spend their time at Thonga studying dive theory and in the pool, we recommend you do all your training at home and then just bring along all the relevant documents. We will then do your 4 x open water dives at Thonga. Remember, you will have to do your training with a PADI instructor.

For those who have not dived within the last 24 months is strongly recommended to take the refresher course. Safety is our first priority and the resident PADI instructor will guide you through the course.

Continuing Education

Advanced Open Water Diver and Junior Advanced Open Water Diver

This qualification provides the qualified diver with additional experience through a structured, well-supervised course and will allow you to dive up to depths of 30m. There are two mandatory dives, the Deep Diver and the Navigation Diver and 3 elective dives.

At Thonga Beach Lodge Marine Centre we make every effort to ensure that our guests have an awesome experience, but we will not compromise safety and will not take people diving if we feel they are not capable of diving the current conditions. All courses are weather and tide dependent.

Boat Launching

Boat Launching (Diving & Ocean Experience)

The boat is launched with a tractor in front of the lodge and can only be done around the low tide because of the large shore break waves that come up at high tide. When the tide is low in the morning launches will be done early, when the low tide is in the afternoon, launches will be later. For this reason, when the boat is launched, it is not possible to launch for another dive later in the day. We can do 2 dives in a day, but then we take 2 cylinders with us as well as food and drinks for a 2 dive excursion.

Please note that the launch site for the boat at Mabibi is particularly difficult due to large surf and a launch site exposed to the full force of the Indian Ocean. It will be at the skipper’s discretion whether to launch the boat and there is a minimum age limit for the boat of 12 years. This is also at to the skipper’s discretion should he feel the sea is calm enough to take out younger boat riders. We do have to cancel many launches for safety reasons but often the snorkel pool is still safe enough to enjoy when we cannot launch the boat.

It is best to plan your diving around the summer months from December to June for the best chance of good sea conditions. It is also advisable to visit when the low tide is in the morning.
