Both Croatia and Slovenia's destinations are equally beautiful in their own ways. Slovenia is well known for its natural beauty from lakes, waterfalls, and gorgeous countryside. The country has beaches and vineyards and its cities and towns are often less frequented by hordes of tourists. So you can expect fewer crowds and beautiful sites that you can enjoy with ease.  Croatia’s coastal towns are historic and pretty, and when you go beyond the bigger touristy centers you will be able to appreciate the beauty of this Balkan country.  Slovenia showcases fairytale towns and sites, without the price tag of popular European cities. Croatia has a good blend of culture, nature, and modern and coastal landscapes.
