Cala Martina or Ca na Martina is situated at four kilometres from Santa Eulària des Riu, located between Cala s'Argamassa and Cala Gat, as well as next to the village of s'Argamassa. From its coast you can see the islands and small islands of en Caragoler, en Moreneller, Illa Rodona and Illa de Santa Eulària or Illa Gran. You can reach these places by boat, the red coral and the caves are very popular amongst the divers. On the beach you can also see these creations of nature.
This u-shaped sea inlet is quite big, the beach has fine-grained clear sand and the slope is gentle (at 30 metres from the coast there is a depth of only 1,8 metres).
This sandy area is developed and it has transparent water. It is open to the wind from the south which normally blows from the sea and is quite moderate. These conditions explain that Ca na Martina is an excellent coastal stretch for sailing sports.
The sand and the rocks on the ground are covered by seaweed and this is why diving on the surface is recommended. The nearest port facilities are located at Port Esportiu Santa Eulària des Riu.
The accessibility by car is easy following the signs. The private car can be left on a free parking area in the surroundings. You can also reach this beach with the public transport. The nearest bus stop is located at three hectometres.
