Sandy beach on the shores of lake Prespa. Water is clean and it's quite shallow, so you can take your children there too. There is a restaurant on the beach whare you can have a glass of juice, wine, grab a meal or have an ice-cream.
Only disadvantage is lack of any market, so you have to drive 5-10 minutes to the nearest store.
There are free parasols and deck-chairs. Also, there are free showers on the beach, and locked showers just for camp users.
I woke around 6:30 each morning and did my morning swim. It was so so refreshing. There was only me, and one old man fishing. Nobody else. Fantastic. Around noon came more people, but beach is big and you can claim your part of the land with no problem.
Restaurant on the beach has quite good selection of local food and standard dishes (e.g.Wiener schintzel) but what I found weird was they had no fish dishes (I don't eat fish at all, but my sister's boyfriend wanted to eat fish). Prices are quite low and the food is okay.
