Meda Gran, the largest island in the group, has an area of 0.18 km² (0.1 sq mi) and is the only island of a considerable size.
It has some Mediterranean vegetation and a 19th-century lighthouse on it.
The lighthouse was built on La Meda Gran in 1866; it had a resident lighthouse keeper until 1932 when the installation of an automatic light made him redundant.
Currently the island has a solar-powered automatic lighthouse.

Meda Xica, the second largest island, has a total surface of only 0.02 km² (0.01 sq mi).

Carall (or Cavall) Bernat, Tascons Grossos, Medellot, Tascons Petits and Ferrenelles are mere steep rocky outcrops jutting out from the sea.
