The beaches at Sóller
Sóller and Port de Sóller are located in the northwestern part of Majorca. There are two beaches:
1) Centrally located by the city and harbour with a lively seafront, and
2) which is the nice Playa d'en Repic, which is a narrow sandy beach with lots of small stones the first few meters.
The seafront at both beaches ensures that something for everyone, and the nearby town is incredibly beautiful.
None of the beaches can be said to be particularly child friendly, since the water is relatively deep. However, the most centrally located beach is considered the most most child-friendly of the two - maybe because you have the option to rent SUPs and pedalos.
