Although it is the poster child of the Slovenian tourist industry, Lake Bled isn't particularly busy in September. In fact, sections of the 6km circuit can be serene, with sweeping views of the glacial lake and its fairytale island, complete with handsome church reached via a grand stone staircase. On your way round, you'll pass several impressive mansion houses, well-placed benches, boardwalks and jetties, where you can sunbathe.
