On a clear day it is possible to see the neighbouring island of Porto Santo, 30 miles to the north.The footpath northwards towards Pico Ruivo is an important tourist attraction, with a daily average of 1000 tourists trekking on it.There is easy road access to the summit, with a large car park, a restaurant and souvenir shop. In 2011, an Air Defence Radar Station was built at the top of the mountain near the tourist facilities.
