There is a lot of water around this area outside summer, and closer to the beach dunes. It is a good spot for birdwatching from, particularly early morning (late in the day you look towards the sun). The habitat types are varied around here so expect to see a good range of birds. A bit of exploring might be rewarded and further up the track there is good coastal walking on the Camí de Cavalls.
Turn left off the main Mercadel-Fornells road at the Mahón crossroads. After about 3km you will see Cala Tirant beach signposted on the right. You can easily stop anywhere along the track.
Binoculars very useful as you'll usually be viewing from a distance.
