If you want to enjoy sunshine, paradise islands and the company of Kuna indians, head to San Blas islands on the shore of Panama. You can take a 20-seat small airplane from Panama City that will take you to one of the islands landing on a ~100m long airstrip. That's quite awesome! You will be taken to you accomodation with a canoe by the indians. You will be able to see many small islands, swim, fish and enjoy the food that the guys actually catch fresh from the sea. Relax in a hammock and let the small breeze make the weather just perfect. Remember to taste some Abuela rum and don't wonder if you end up fishing with only a line and a hook..If the place is right, you will probably catch a shiny silver fish with every throw like I did!
