The island of Santa Luzia can be toured only by walking, under the rules imposed by the nature reserve status, taking also into account that the territory is quite bumpy, though the vegetation is sparse, and the highest point known for Topona is 395 meters high.

The islets Branco and Raso are located between Santa Luzia and São Nicolau. They are, respectively, 7 and 3 square kilometers long, with steep cliffs. The first one has a 170 meter – long plateau; the second one has a 327 meter-long plateau covered with white guano.
