Pico do Areeiro, Mountain summit in Madeira, Portugal

Pico do Areeiro is a mountain summit on Madeira rising to 1,818 m, the island's third-highest peak. Its upper slopes are bare dark brown and grey rock, cut into sharp ridges and deep clefts, with patches of green vegetation on the ledges. A narrow dirt path and yellow-flowered shrubs lie at the lower edge.

The road from Poiso Pass opened Pico do Areeiro to vehicles, making it Madeira's most visited summit, unlike the higher Pico Ruivo and Pico das Torres. Until the 1960s the trail to Pico Ruivo was a serious climbing feat; secured stairways and the tunnel through Pico do Gato later made it manageable. In 2011 the Portuguese Air Force built a radar station beside the summit facilities.

The name Areeiro comes from areeiro, Portuguese for a sandy or gravelly place, though the summit itself is bare rock. In May and June the slopes below the peak flower with Cytisus scoparius, and the endemic Echium candicans, called "Pride of Madeira", opens blue-violet flower spikes up to 45 cm long. Local guides point out the Madeira eyebright and the orchid Orchis scopulorum among the rocks.

A road from the Poiso pass, branching off the Funchal road, ends just below the summit, where two large car parks and a cafeteria with a souvenir shop stand; the summit column is a few steps from the cafeteria. Snow and ice can briefly make the road slippery in winter. The PR1 path to Pico Ruivo takes three to three and a half hours; its eastern ridge route has been closed since 2018, so hikers use the western route through the Pico do Gato tunnel.

The PR1 path to Pico Ruivo crosses the Pico do Gato through a tunnel, and since 2018 the eastern ridge route over the crest has been permanently closed because of slope collapses; only the western route through the Pico das Torres tunnel remains open. The walk to the Pico Ruivo summit column takes three to three and a half hours.
