Slovenia is a progressive, fast-growing country in Central Europe with an ever-increasing retirement population, but many people probably haven't considered retiring there. Although it is small, Slovenia is not only one of the most sustainable countries in the world, but it also has an impressive infrastructure. Thankfully, it manages to maintain its old-world charm. Slovenia is far less crowded than other places of similar size in Europe. Just over 2 million people live there.
If you're a nature-minded retiree, you'll love the temperate climate and diversity of landscapes to choose from, including a 30-mile Mediterranean coastline, mountain vistas, and alpine meadows. Explore the small lakeside community of Bled if you're seeking a location with natural beauty, but fewer tourists. There are bike paths, coffee shops, and boutiques in this unique town, with outdoor activities year-round.
