On which days is entry to Karkonosze National Park free?

Entry to Karkonosze National Park (KPN) is free for everyone on three days a year: 16 January, 24 May and 10 August. The exemption does not apply to Kamieńczyk Waterfall — on those days you still pay 16 PLN (reduced 8 PLN) to enter its gorge. Current rules: kpn.gov.pl (opens in a new tab).
