Between March and the end of April the chunk of Gran Canaria between the Caldera de los Marteles and Tenteniguada, high up in the hills above Telde, goes technicolour.
This spring explosion of colour comes from a range of native species with purple, blue, yellow and red flowers. The most famous are the tajinastes or viper's bugloss flowers but buttercups, aeoniums, cinerarias, poppies and sonchus (giant dandelions ) all flower here at the same time.
Most of the tajinastes are blue, pink or purple but the challenge is to spot one of the rare red flowered plants.
You can walk a long loop from the Caldera de los Marteles down to Tenteniguada (about 6km) and back up again but the bulk flowers are within a kilometre of the road just past the clump of pine trees. There is no bus back up so you either walk or use the old two-car trick. Bring food and water as there is nothing up here once you start walking (there is a snack van by the mirador).
To reach the Caldera, put the Caldera de los Marteles viewpoint into Google Maps and drive up through Telde and Lomo Magullo. Some Bus 13s also stops here on route from Telde to Tenteniguada but not all. If you get the bus to Los Marteles, you can walk back down to Tenteniguada and get another bus back to Telde and then on to Las Palmas or the resorts. To be honest, it is quicker and easier to do this with a hire car.
The flowers are down the hill on the side of the road opposite the crater. Just walk down the wide path until your eyes hurt and you are right there amongst Gran Canaria's most spectacular spring display.
