The Punkva Caves (Punkevní jeskyně) are the star attraction of the Moravian Karst (Moravský kras) in South Moravia. The tour combines an underground walk to the floor of the 138.7 m deep Macocha Abyss with an electric-boat cruise along the subterranean Punkva River — a rare walk-and-boat format that makes it one of Czechia's most popular caves. First explored in the early 20th century by Professor Karel Absolon, the site remains hugely in demand: in 2026, summer weekends and the whole April–October season routinely sell out weeks ahead, so booking is essentially mandatory, while the clifftop viewpoints over the abyss stay free. It suits travelers who want a nature/cave outing paired with a short river cruise.

Good to know
RulesEntry is by timed slot with limited capacity. In peak season and on weekends it sells out weeks ahead — reserve via the Skalní mlýn Central Information Service (phone or online eVstupenky). Individuals can book up to one year in advance.
RulesReserved tickets must be collected at the Skalní mlýn info center at least 40 minutes before your tour, or the booking may be forfeited. Arrive with a buffer.
SeasonThe cave stays 7–8 °C with 99% humidity even in midsummer. Bring long sleeves, a light jacket and non-slip shoes regardless of the season outside.
SafetyThe walking route is about 1,250 m with 198 steps on wet, slippery ground. Follow the crew's instructions when boarding and leaving the boat; go easy if you have knee or back issues.
MannersDo not touch the stalactites or stalagmites and stay on the marked path. Photography is generally allowed but flash/tripods may be restricted — follow the guide and keep pace with your group.
CautionHalf-day tours from Brno are convenient but can add a hefty markup over the entrance fee. If you go independently, book at the official price via the website/info center, and mind your belongings at the busy Skalní mlýn car park.
SafetyThe caves are not barrier-free. Wheelchair users can, by prior arrangement, access only the dry sections on the first or last tour of the day.
Practical info
The nearest railway station is Blansko; the hub is the Skalní mlýn Central Information Center, from which the caves are about 1.6 km on foot or reachable by the road eco-train and cable car. The info center runs roughly 8:00–16:30 (Apr–Sep) and 8:00–15:00 (Oct–Mar); prices, hours and any winter closures change by season, so confirm the latest details on the official site.
