Hi Lorraine, We just returned for Alcudia and found swimming at Viva Blue easy. I suggest contacting the resort and make a reservation for a swim lane. I believe the cost was $5.00 each/EUR0. Great pool and nice to be outside. (Canadian here so we don’t have that option). I rode a portion of the 70.3 bike course. It’s pretty awesome and the climbing is fun (Cole de Femenia).
Hopefully you can hug the shore line and swim the ocean. Have fun and be safe!
