European beaches offer an exceptional opportunity to enjoy a seaside setting and be close to the rich occidental culture of European nations.
I would suggest European beach destinations for the spring, summer and fall time, but not winter as you probably will find much better weather in tropical areas such as the Caribbean, southern hemisphere destinations, and Pacific island destinations.
Don’t fall in the trap of thinking you got yourself cheap holidays in Europe in the winter time, it’s just a consequence of sub par weather. Although some of these destinations are good year long, I strongly advise you look into tropical destinations, perhaps in the Americas (As cited above, Caribbean destinations are great, year long), or Pacific.
There are in fact interesting activities in Europe, even in the winter time, but beach activities don’t show up on that list.
