I went to split a few years back...if i remember correctly theres a lot of rocky coves around, which are excellent if you are like me and enjoy diving and snorkelling, theres a lot of stuff to see! However, if your like me also dont step on sea urchins-they hurt! But at least the water is crystal clear so you can see them. Also, we went on a day trip to an almost empty island, cant remember the name of it, but we had a whole beach to ourselves, and theres plenty of these islands around, if your going with your boyfriend it will be very romantic
