St. Peter's pool, Marsaxlokk - not the easiest to access, but definitely worth it
St. Peter's pool is located at the tip of Delimara Point in the south west of Malta. Located on the way to Marsaxlokk Bay, if you're walking from the town, it's not that easy to get to, might take roughly 30-40 minutes to reach the beach, but it's all worth it. See the pictures below to get a feel for it. Perfect spot for BBQ, swimming, jumping, diving, sunbathing, enjoying the company of yourself and your friends and people you know or don't know, yet. I was there just yesterday, and while I was kind of skeptical whether it's worth going to or not, if we forget the hurting sunburn I managed to get, it's definitely a place worth checking out.
Note that there are no shops, cafeterias, or even toilets nearby. So in case of drinks and food, make sure you bring them with you. And toilet - you can find some bushes.
