The Galápagos Islands in 5 days

A 2.5 km paved path from Puerto Ayora through cactus and palo santo forest to Playa Brava, a long white beach where marine iguanas bask.

Ten minutes' walk from Puerto Ayora, it has bred giant tortoises since 1964 and displays Lonesome George, the last Pinta tortoise, who died in 2012.

A bare cinder cone off Santiago: wooden steps climb to 114 metres, with two crescent bays and Pinnacle Rock, the archipelago's most photographed view, below.

Five minutes from the Puerto Villamil dock, a boardwalk through mangroves leads to a sheltered, shallow lagoon where sea lions swim around snorkellers.

Collapsed lava off south-west Isabela has left arches and flooded tunnels; walk the basalt bridges, then snorkel with green turtles, eagle rays and seahorses.

An hour's walk on red earth to the rim of a caldera about 9 by 7 km, last active in 2018; mornings are often misty.

A 3 km trail on Española past booby colonies, red and green marine iguanas, a clifftop blowhole and nesting waved albatrosses from April to December.

An hour by boat from Puerto Baquerizo Moreno, two 150-metre tuff blocks split by a narrow channel where Galápagos and hammerhead sharks gather.
