Kleť Mountain is a favourite year-round destination for families with children, as well as for able sportsmen. The peak is accessible either by chair lift from the village of Krásetín or by trekking along several educational trails in the protected Blanský Forest natural reserve. From the oldest stone lookout tower in Bohemia, there is a great view of a large part of South Bohemia - if the weather conditions are good, you can even see the snow-capped peaks of the Austrian Alps. In the summer months, visitors can enter the observatory, which houses the largest telescope in the Czech Republic. In optimal conditions, projections of sunspots can be seen.
