There is a direct bus connection to Veltrusy from Prague, Kralupy nad Vltavou and Mělník (Lines 370, 372, 470, 473).
Veltrusy is located near the busy line Prague-Děčín. The nearest station is Nelahozeves (1165m by the shortest route). Fast train connections usually stop in Kralupy nad Vltavou.
By boat There is no regular passenger transport, those who are a daredevil can try to hitch a ride on a cargo ship on the route between Prague and Melnik. There is a freight port in Miřejovice at the dam, if the skiffs don't stop there, be sure that they will at least slow down in the lock of the dam.
The nearest international airport is in Prague. The airport where you could land your MiG, L410 or Albatros is also in Vodochody, but we don't know if they will let you in. If, like the rest of normal people, you have only a Cessna or other light aircraft, or you own a glider with or without an engine, or at least have a parachute, you can land at the airport in Sazena (9.5 km by road).
