Salobrar de Campos is the salt lagoon right next to Es Trenc that most beach tourists completely miss. Embedded in the Natural Park Es Trenc, Salobrar de Campos, 172 hectares, protected since 2017. This is where the around 300 flamingos you see on Mallorca postcards live, plus around 170 other bird species depending on season (sea eagles, marsh harriers, ospreys in autumn and winter).
For flamingos, the best time is late summer to end of April. In high summer they are mostly elsewhere because the water gets too warm and too salty. From November to February you see the largest flocks. I was there at the end of January last time, around 200 flamingos in one lagoon, water reflecting pink at the bottom.
The observation points you reach via the Ma-6040 road between Campos and the Colònia. A wooden observation tower stands roughly halfway (signposted 'Mirador'), free, just drive there and park at the roadside. Bringing binoculars is mandatory, without them you only see white dots. A good smartphone camera does nothing for you without a tele lens.
You cannot enter the lagoons, that is protected territory. Hiking paths lead around through the dunes, well signposted from the Mirador onwards. If you take birds seriously, come early morning (before 9) or an hour before sunset, that is when they are active. At midday most of them stand motionless in the shallow water. Mosquitoes in autumn, in spring barely any.
