Islands > Tower (Genovesa)

Tower Island could serve as a film set for a secret submarine base! The southwestern part of the island is an ocean-filled caldera ringed by the outer edges of a sizeable and mostly submerged volcano. The island sits to the northwest, slightly removed from the Galapagos archipelago. It is also known as “Bird Island,” a name it lives up to in a spectacular way. Landing on the white coral sands of Darwin Bay and walking up the beach, you will be surrounded by the bustling activity of “great frigate birds.” Puffball-chicks with their proud papás—who sport their bulging scarlet throat-sacks—crowd the surrounding branches, while both yellow-crowned and lava herons feed by the shore. Farther along you will discover a stunning series of sheltered pools set into a rocky outcrop, forming another natural film set. A trail beside the pools leads up to a cliff overlooking the caldera, where pairs of swallow-tailed gulls, the only nocturnal gulls in the world, can be seen nesting at the cliff’s edge. Lava gulls and pintail ducks ride the sea breezes nearby.

A brief panga ride brings us to the base of those same cliffs to reveal the full variety of species sheltering in the ledges and crevices created by the weathered basalt. Among them, red–billed tropic birds enter and leave their nests trailing exotic kite-like tails. This is also an intriguing place to go deep-water snorkeling, where the truly fortunate swimmer can spot one of the giant manta rays that frequent the inner bay along the cliff walls.

Across the bay are Prince Philip’s Steps, named for a visit by the British Monarch in 1964. The 25-meter (81-foot) stairway leads to a narrow stretch of land that opens out onto the plateau surrounding Darwin Bay, and extends to form the north side of the island. Red-footed boobies wrap their webbed feet around branches to perch in the bushes, and, in contrast, their “masked-booby” cousins dot the surface of the scrublands beyond. Crossing through the sparse vegetation, you will come to a broad lava field that extends towards the sea—this forms the north shore. “Storm petrels” flutter out over the ocean in swarms, then return to nest in the cracks and tunnels of the lava field, where their predator, the short-eared owl, is a frequent visitor.
