Prague River Cruise to Devil’s Channel
The Prague River Cruise to Devil’s Channel is a 45-minute small-boat tour that departs from Čech Bridge (Pier 6) and travels along the Vltava past Charles Bridge and Prague Castle before entering the Čertovka — the narrow medieval channel that divides Malá Strana from Kampa Island. The cruise includes a live guide, passes the Grand Priory Mill, and offers a perspective on Prague that the larger sightseeing boats simply cannot access. It is one of the most intimate and highly rated river experiences in the city.
Prague has a Venice. Most visitors never find it. Tucked behind Charles Bridge, running between the ancient houses of Malá Strana and the green lawns of Kampa Island, the Devil’s Channel — Čertovka in Czech — is a narrow medieval waterway that dates back to the Middle Ages and looks almost entirely unchanged. The Prague River Cruise to Devil’s Channel takes you directly into it on a small, manoeuvrable boat, guided by someone who knows exactly what you are looking at and why it matters.
This is not the cruise for panoramic views and famous skylines — though you get those too on the approach. This is the cruise for the hidden side of Prague: the millwheels, the medieval house facades growing straight from the water, and the eerie quiet of a channel that feels a world away from the tourist-packed bridge just metres above.

What Is Included?
The Prague River Cruise to Devil’s Channel includes a 45-minute small-boat tour with a live guide, departing from Čech Bridge Pier 6. The route passes Prague Castle and Charles Bridge before entering the Čertovka channel. The boat is electric and solar-powered, making it quiet enough to hear the millwheel turning inside the channel. In winter, a covered and heated vessel is used.
The live guide is central to what makes this cruise different. Unlike the larger sightseeing boats where the commentary is pre-recorded and broadcast to a crowd, this is a small-boat experience where the guide is right there with you. Reviewers consistently highlight the guides’ local knowledge, their sense of humour, and the way they tailor the tour to the group on board — answering questions, pointing out details that would otherwise go unnoticed, and making the whole experience feel personal rather than packaged.
The electric, solar-powered boat is another notable feature. It runs silently, which matters inside the narrow confines of the Devil’s Channel — you can actually hear the clatter of the Grand Priory Mill wheel turning, an experience that would be lost on a noisy diesel-powered vessel.
Buy This TicketThe Route: From the Vltava into Čertovka
The cruise begins on the open Vltava with panoramic views of Prague Castle and Charles Bridge, then enters the Čertovka channel — a narrow medieval waterway originally built as a millrace that now separates Malá Strana from Kampa Island. Inside the channel, the boat passes medieval houses that appear to rise directly from the water, the Grand Priory Mill, and several other preserved mill structures dating back centuries.
The opening stretch of the cruise, on the open Vltava, gives you the classic Prague river perspective: the castle on the hill, the Charles Bridge towers, and the broad sweep of the embankment. But what makes this tour distinctive is the moment the boat turns left and slips under the small stone bridge that marks the entrance to the Čertovka.
Inside the channel, Prague changes completely. The scale drops from grand to intimate. Buildings that look like ordinary Malá Strana facades from the street reveal their full waterfront height from the channel — several storeys of weathered stone and ancient render dropping straight to the water. The Grand Priory Mill appears around a bend, its wooden wheel still turning, its mechanics essentially unchanged from the medieval period. Visitors who have previously walked Kampa Island often find the experience of seeing it from the water entirely transformative — it is, genuinely, a different city.

The Legend of the Devil’s Channel
The Čertovka — Devil’s Channel — is said to have taken its name in the 19th century from a woman of notably devilish character who lived nearby at Maltese Square. The channel itself is far older, constructed in the Middle Ages by the Knights Hospitaller as a millrace to power the mills along Kampa Island. Three of those mills survive to this day.
The name has stuck for over two centuries, and it suits the channel’s character. In low light, the narrow waterway with its overhanging buildings and turning millwheel has the quality of a fairy tale — beautiful and slightly uncanny in equal measure. The live guide typically tells the story of the name’s origin, which makes for one of the more memorable moments of the tour.

How It Compares to Other Prague River Cruises
The Devil’s Channel cruise is unique among standard Prague river cruise options in that it accesses the Čertovka itself — something the larger sightseeing vessels cannot do. It is shorter than most cruises (45 minutes), operates on small boats with live guides rather than recorded audio, and is consistently rated among the most intimate and memorable river experiences in the city.
The key distinction is access. The larger panoramic cruises on the main Vltava are excellent for broad waterfront views and architectural overviews. This cruise is for the detail — the hidden channel, the medieval mills, the perspectives that require a small boat and a knowledgeable guide. Many visitors to Prague choose to do both: a panoramic cruise for the skyline, and the Devil’s Channel cruise for something genuinely different.

Who Is This Cruise Best For?
This cruise suits visitors who want something beyond the standard sightseeing experience — those interested in the hidden, medieval side of Prague rather than just its famous skyline. The small boat format and live guide make it particularly well suited to couples, small groups, and anyone who finds large group tours impersonal.
It is also an excellent choice for:
- Second and third-time visitors to Prague who have already seen the main landmarks and want a different perspective
- Photography enthusiasts — the medieval channel architecture and millwheels are unlike anything else in the city, and the small boat gets you close
- History and architecture lovers who want the story behind what they are seeing, not just the view
- Couples for whom the intimate, quiet boat on a narrow medieval waterway makes for a genuinely romantic experience

Frequently Asked Questions
What is the Devil’s Channel (Čertovka)?
The Čertovka is a 740-metre medieval canal built by the Knights of Malta in the 12th century to power mills along its course. It separates Kampa Island from the mainland of Malá Strana and is accessible only by small boats — larger Vltava vessels cannot enter it. See The Devil’s Channel: Prague’s Hidden Waterway for the full history.
Does the cruise go under Charles Bridge?
Yes. The route passes Charles Bridge on the main Vltava before turning into the Čertovka canal — giving passengers both the panoramic river view and the intimate canal experience.
Is the guide live or recorded?
The cruise operates with a live guide — one of the features that distinguishes it from standard sightseeing cruises using pre-recorded audio.
What happens if the canal is inaccessible due to high water?
The Čertovka section may be shortened or omitted during periods of unusually high Vltava water levels. Passengers are informed in advance when this is the case.
How does this cruise compare to the Canal Cruise Around Charles Bridge?
Both enter the Čertovka, but differ in boat type and departure point. This cruise uses a modern electric boat with a live guide departing from Čech Bridge; the Canal Cruise uses traditional wooden boats departing from beneath Charles Bridge and includes a drink, snack, and museum entry. See Prague Canal Cruise Around Charles Bridge for the comparison.
