Całowanie (meaning ‘kissing’ in Polish) refers to a village and a swamp in the Southern part of Mazowiecki National Park in Otwock District. The sand dune in the centre of the swamp, which used to be a sandbank in Vistula river, revealed traces of a prehistoric settlement. The swamp itself is now a Bog Reserve, one of the gems of Mazowsze natural heritage, thanks to its flora.
