A must if you go to Palma de Mallorca and you rent a car! The access to the cap is quite an adventure as the roads are tight but full of nature. Save it for a day when the weather is playing up and the beach is not the first option. I lived for 3 months nearby and I was following the track to the cap every now and then, so I was able to appreciate the view from every time of the day. In high season the roads as they are very curvy and you need to be a bit more than a beginner to get there, go with enough time in case the queue of cars is too long and there’s no place to park. A bus is also a good option and you save the time and stress trying to find a spot!
