Tortuga Bay, Santa Cruz
The longest beach in the archipelago is a 45-minute walk from Puerto Ayora on Santa Cruz. The first beach has strong currents and is popular with surfers, but walk to the end and soak in a sheltered shallow lagoon at Playa Mansa, where marine turtles lay eggs at night.
Bachas Beach, Santa Cruz
This beach is named for the remains of wrecked U.S. military barges from World War II, and the rusty metal parts remain visible, jutting out of the white sand. The beach is otherwise pristine and covered in sally lightfoot crabs, while the lagoons behind are home to flamingos.
Puerto Chino, San Cristóbal
San Cristóbal has many beautiful beaches — Playa del Amor, La Lobería, and Cerro Brujo — but this beach is one of the quietest. Used as a cool-off after a trip to the highlands, the small beach is backed by mangroves and is also good for surfing.
Puerto Villamil, Isabela
The main port on Isabela is the most laid-back town in the archipelago, with a peaceful position on a long white-sand beach that is home to a small colony of marine iguanas. Far quieter than other resorts, you may find it difficult to leave.
Post Office Bay, Floreana
This brown-sand beach is hardly the most photogenic in the islands, but the history behind it is interesting. The post office barrel has been running since 1793, so leave a postcard and pick up any mail for your local area. A visit is usually combined with the green-tinged beach of nearby Punta Cormorant, colored by olivine minerals.
