8 Most Fascinating South African Islands and Their Unique Features

Because of isolation, many islands have become home to some of the world’s most unusual and fascinating wildlife. Rich in cultural and geographic diversity, South Africa is an interesting and fun-filled African holiday destination with incredible places and warm hospitality. Aside from being home to 10% of the world’s birds, fish, and plant species, as well as 6% of its mammal and reptile species, the country also boasts incredible islands that attract tons of tourists from all parts of the world. Talking of stunning islands, we are fortunate to live on a part of the planet where we’re spoiled for choice. Among the most enthralling, we selected the eight most fascinating islands in South Africa.

1. Addo Elephant Island Group

The Addo Elephant Island group comprises four uniquely designed islands: Bird Island, Stag Island, Seal Island, and the St Croix island. The group of four islands lays to the south-east of the Addo Elephant Park in the Eastern Cape. They are about an hour away from Port Elizabeth which is colloquially known as “The Friendly City” or “The Windy City. The Addo Elephant Park is generally known to be the third-largest national park in South Africa and finding yourself at the park gives you greater opportunity to explore each of the islands.

Unique Features

Bird Island: The Bird Island which is part of the group of four islands is an important breeding place for marine bird species. Some of the resident birds on the island include Bridled Tern (Sterna anaethetus), Great Frigatebird (Fregata minor), Barred Ground-Dove (Geopelia striata), Common Moorhen (Gallinula chloropus), Greater Crested Tern (Sterna bergii), and Common Mynah (Acridotheres tristis).

Seal Island: Seal Island is a small island lying 360 m north of Bird Island. The Island has no vegetation, soil of any significance, or beach but it supports the habitation of a special seal species known as the Cape fur seals. These piles of seals use the island as their main breeding ground and usually are left in peace.

St. Croix Island: nearer to the town of Port Elizabeth, is home to a large breeding colony of African penguins. The Island lies 4 km offshore between the Coega and Sundays River mouths and it is part of an experiment to study the effects of fishing on penguin breeding and foraging behavior.

Stag Island: Located in the Eastern Cape Area of the country of South Africa, Stag Island is home to various species of fishes and other outdoor adventures.

Can You Visit Addo Elephant Island?

Parts of the Addo Island are Marine Protected Area (MPA), thus, cannot be visited randomly. Boats are not allowed to land on this group of islands, although some charter boats can cruise close enough to see the habitats quite easily. The Addo Elephant National Park MPA was established in2018 in order to achieve the long-term conservation of nature with associated ecosystem services and cultural values.

 2. Dassen Island

The  Dassen Island is the second-largest coastal island on the South African continental shelf after Robben Island in Table Bay. It was named by Dutchman Van Spilbergen in 1601 and was proclaimed a nature reserve in 1987. The Island is managed by Cape Nature.

How to Visit Prince Edward Islands

Prince Edward Island is uninhabited except for occasional biological research teams. Marion Island, for example, is not a tourist destination and access is limited to SANAP team members. Therefore, the only way to travel to the Islands is on board a South African research vessel. Research team members remain on the Marion island for months, but it is also possible to visit the island as part of the relief team

Best Time To Visit South African Islands

South Africa’s climate has seasons but the country is a year-round destination, with varying regional climates and wildlife opportunities. May to August brings in the cold in winter and often hot in summer (November to March) with temperatures reaching the early thirties. However, the weather begins to cool down with frequent rains. The rainy season begins in October and lasts through to April.

Therefore, for a better view of wildlife congregating around the watering holes, visitation will best be in the dry season (May to October) while November to February is perfect to travel for birding, as temperatures remain warm at 22°C-33°C. Meanwhile, the best time to visit the Cape for whale watching is between July and November. September remains the best month to travel to South Africa if you’d like to experience a combination of regions and wildlife.

Which Is The Largest of The South African Islands?

South Africa is one of the few countries surrounded by a number of beautiful Islands. Interestingly, these islands contribute to the history and cultural development of the country. Of course, the most notable of them all is the Robben Island in Table Bay.

Robben Island, the roughly oval-shaped land which stretches 3.3 km (2.1 mi) long north-south, and 1.9 km (1.2 mi) wide, with an area of 5.08 km2 (1.96 sq mi), is considered the largest island in South Africa. Next to it is Dassen Island which lies in the Atlantic Ocean, approximately 55km north-west of Cape Town and 9km off Yzerfontein.
