The islands of the Galapagos

The second largest island in the Galapagos, Santa Cruz is the start and end point for most cruises. Whether you stop here whilst exploring the waters or are spending a few nights on its shores, there's plenty to see. Cycle across the highlands on the lookout for giant tortoise; hike through the lava tunnels; pay a visit to the Charles Darwin Research Station; spend time on the lagoon on a kayaking excursion; and dive below the gin-clear ocean to spot turtles, sea lions and tropical fish. Spend a few hours (or days) on the white-sand Tortuga Beach, soaking up the sun and views and looking out for the marine iguanas arriving ashore. Along the way, you never know how many members of the 'Galapagos 15' you'll see.

The largest of the Galapagos islands, Isla Isabela is the child of six colliding volcanoes, resulting in a rugged and curiously-shaped landscape. This is one of best places to see the archipelago's sea birds nesting on the cliffs and swooping over the water, as well as the endemic penguins who make impressive divers. Off the coast, beautiful coral reefs are a snorkelling and diving paradise. On land, visit Tagus Cove, where pirates once partied, or hike along trails past towering volcanoes - and you can spot up to five different species of giant tortoise.
