A great plan for a sunny day
A little bit up north from the beautiful village of Sant Pol de Mar, you can find the "Platja del Morer".
As you can see in the photo, it's not a superbig beach plenty of bars, which gives it a charming atmosphere.
You can go there taking the train (Rodalies Renfe) to Sant Pol de Mar station. Take a walk through the town (it's worth it) and then continue through the Passeig Marítim until you reach the beach.
If you feel like Indiana Jones that day you can live a little adventure in the Roman ruins next to the beach (they are not really big or impressive, but if you are curious they are just a walk from the beach)
So, take your sunblock, your towel and something to drink and let's go to the beach!
