The Vltava is the longest river in the Czech Republic at 430 km, and its paddling corridor is the most heavily documented in Central Europe. From the confluence of the Teplá and Studená Vltava streams in the Šumava highlands down to the Mělník confluence with the Elbe, it crosses nine distinct hydrological zones. This page documents the sections most commonly navigated by kayakers, with notes on current conditions, permit requirements, and hazard points as recorded through the 2025 season.
Section Overview: Šumava to Český Krumlov
The upper Vltava through Šumava National Park — roughly from Soumarský Most to Vyšší Brod — is the most ecologically sensitive stretch. Navigation here is subject to a seasonal permit issued by the Šumava National Park administration. In 2025, the permit window ran from 1 May to 30 September, with daily quotas of 60 boats per segment to limit disturbance to nesting birds along the Vltava meanders.
The current grade varies between I and II+ depending on water level. The Čertova stěna rock formation below Čertova Zeď creates a class II rapid in average flow; at high water it steps up. There are five mandatory portages in this section, clearly marked. The distance from Soumarský Most to Vyšší Brod is approximately 52 km, typically covered in three days with overnight camping at designated sites.
Permit Application Process
Permits for the Šumava section are applied for online through the national park portal at npsumava.cz. Applications open on 1 March each year. Groups larger than 10 boats require a separate group permit. The permit is non-transferable and must be carried on the water.
Vyšší Brod to Český Krumlov (22 km)
Below the Vyšší Brod dam, the river enters a wider valley and the current slows. This section is grade I throughout, with the exception of the Čertův Mlýn weir at kilometre 9, which requires a short portage on the right bank. The segment passes through the town of Rožmberk nad Vltavou, where a public landing and basic equipment rental station operate in season.
Český Krumlov marks the end of the upper Vltava paddling zone and the beginning of the middle corridor. The historic weir in the town centre is non-navigable; portage infrastructure is well maintained and signed in Czech and German. Kayak storage facilities in Český Krumlov accept boats for an overnight fee.
Middle Vltava: Český Krumlov to Písek (74 km)
This section is the most frequented by recreational paddlers. Water grade holds at I with occasional II in higher-flow periods. Seven weirs require portage; four of them have established slipways with rollers. The Zlatá Koruna weir at km 18 is the most technically demanding portage — the bank is steep and slippery in wet conditions. Paddlers with loaded boats often use a rope system from the bank.
Camping options exist at three points along the route, all registered with the municipal offices of the respective villages. Wild camping within 50 m of the riverbank is prohibited by Czech water law (Act No. 254/2001 Coll.).
Flow Monitoring
The Czech Hydrometeorological Institute maintains real-time gauge readings at Písek (station ID 1690) and Kaplice (station ID 1560). Safe recreational kayaking on this section is generally possible between flow levels of 15–80 m³/s at the Písek gauge. Above 100 m³/s the weir approaches become hazardous for inexperienced paddlers.
Lower Vltava: Písek to Prague (110 km)
The lower section passes through the Orlík reservoir — a 68 km flatwater impoundment requiring motorised transport or significant paddling effort. Most kayakers exit at Písek, reload at Písek's western bank, and re-launch below the Orlík dam near Písek's rail station. The section from Písek to Prague covers 110 km of mixed terrain with grades I–II.
The Prague urban section presents specific hazards: commercial boat traffic, weir backwash below the Císařský ostrov channel, and restricted zones near Braník and Nusle bridges. Paddlers entering Prague should follow the marked channel on the right bank and exit at the Císařský ostrov paddling base in Troja, which operates as the main kayak hub for the capital.
Equipment Notes
- Closed-deck kayaks recommended for the Šumava section; open canoes are permitted but less practical in the rocky upper reaches.
- Personal flotation devices (PFDs) are legally required for all paddlers under Czech water law at all times.
- Helmet use is not legally mandated but recommended for grade II+ sections.
- Dry bags rated to at least IP67 are standard for electronics and documents.
- Throw bags are required on any commercial guided trip by Czech water rescue standards.
