The Nida is a left tributary of the Vistula, 154.3 km long. It flows through the Przedborska Upland, the Kielce Upland and the Nidziańska Basin to the Sandomierska Valley. The initial section of the river, up to the junction with Czarna Nida between Żerniki and Brzegi, is called Biała Nida. The Biała Nida meanders and receives its largest tributary, the Łososina, which widens its bed to join the Czarna Nida above Brzegi. The Czarna Nida, which is a 68.7 km long left tributary of the Nida, flows through the Świętokrzyskie Mountains and the Szydłowski Foothills.
It is considered the most beautiful river in Poland, at times it is wild and dark, at times it is friendly and warm. Her numerous tricks bring a lot of uncertainty and surprises. The number of obstacles means that sailing on it requires considerable skill.
On Czarna Nida, capsizes and kayak getting stuck may occur, but there are no places that would threaten the kayaker's life, e.g. roadsides, dams, weirs, etc. The only place on Czarna Nida that forces kayakers to get out of their kayaks and move them about 150-200 m , this is the dam in Wolica.
The popularity of recreational and tourist kayaking is growing every year and therefore the number of companies organizing kayaking trips and renting kayaks is increasing. The owners help in choosing the route, have cars with trailers, and provide full logistics. One-day and weekend kayaking trips are the most popular. The companies' offer is addressed to those who want to spend only one afternoon or a weekend in a kayak combined with pitching a tent, having a bonfire and relaxing in the bosom of nature. However, if someone is tempted to spend longer time on the water, a week-long kayaking trip on the Nida River from Mniszek to Krzyżanowice Dolne is also possible.
A list of entities organizing kayaking trips on the Nida River, including equipment rental, is available in the Tourist Guide of the Świętokrzyskie Voivodeship (pages 108-110).
