The island

Assumption in short.

Assumption lies a thousand one hundred and thirty-five kilometres south west of Victoria, just south of Aldabra. Where its neighbour was saved by being useless to everybody, Assumption was mined for guano for most of the twentieth century and carries the marks of it.

Can you go?

Restricted. There is no ordinary tourism.

The island

Charted on a feast day

Captain Nicolas Morphey charted the island on 14 August 1756 and named it for the Feast of the Assumption the following day. It was leased in 1908 for a coconut plantation, and the guano camp that followed ran from 1907 until 1983 and stripped most of the original vegetation and wildlife off it.

That is the difference between the two islands in one sentence. Aldabra survived because nobody could make it pay. Assumption did not.

The island

Dunes and water

The island has sand dunes, which are rare in Seychelles, and the visibility in the water around it is exceptional. It was used as a location for underwater documentary filming in the mid-twentieth century for exactly that reason.

There is an airstrip and limited facilities, and the island is tied to the conservation and surveillance logistics of the Aldabra group next door.
