Head for the water. There are more than 90 beaches, most of them very child friendly. We recommend Punta del Papagayo for its sandy coves. In Puerto Calero, Lanzarote's Submarine Safari lets you sit on the floor of the seabed for up to an hour and watch everything walk or swim on by, while the Canarian Cetacean Museum teaches you all about whales and dolphins. Lanzarote also has some very good surf, plus a great windsurfing school at Famara.
Go sailing. There are plenty of opportunities to get on a boat around the island and for children to learn the ropes catamaran-sailing (such a smooth ride that even buggies are allowed on board!).
The volcano – or at least the lava it left behind – tempers just about everything about the island. Learn more about its history at Timanfaya Park, with more than 100 craters, known as the Montañas del Fuego (Fire Mountains), left as a result of the last buzz of activity, plus a restaurant that uses the geothermal heat for cooking (see below).
Not only does Lanzarote eschew the high-rise blocks of its Spanish counterparts, it’s also got a few architectural gems up its sleeve, including El Mirador del Rio, a rock-and-glass lookout post overlooking neighbouring Graciosa, and Jameos del Agua, connecting caves and caverns that now house a subterranean restaurant with the feel of a James Bond movie set.
For some respite from the lunar landscape, take a stroll around Guinate Tropical Park in the north of the island – a little piece of paradise with waterfalls, tropical gardens and a great collection of bird life.
Head for the themeparks: Aquapark Lanzarote, the only water park on the island, and the Rancho Texas Theme Park, which has a great zoo and lots of Wild West attractions.
Take a boat-trip further afield. There are several daily ferry crossings to Fuerteventura (45 minutes).
