The boat slips away from the stone edge beneath Charles Bridge and the city exhales: chimneys, tiled roofs and the fortress line of Prague Castle slide into view as the Vltava nudges the hull. In fifty minutes the captain steers into Čertovka, the Devil's Channel—an intimate blind arm of the river that threads behind Kampa Island and past the Grand Priory Mill.
This narrow channel dates to medieval water management and the preserved mill buildings are reminders of Prague's river-driven craft economy. Geologically the Vltava carves through Bohemian granite and Paleozoic bedrock, and here the current slows enough to let eddies and reflections shape the experience; culturally the channel has fed local folklore and inspired painters who worked along its muted banks.
Expect low bridges, millstones peeking from waterlines and houses that appear to rise straight from the river. The captain's commentary covers the Charles Bridge panorama, the blind stream’s history, and the mills' role in feeding the city.
Practical tips: the tour is short (50 minutes) and accessible to most travelers, but boarding requires careful steps; choose a side seat for castle views. Morning light is best for photos; late-afternoon trips soften the river and reduce glare. Bring a windbreaker, a camera with a tight zoom for architectural details, and a reusable bottle — vendors nearby are limited from the water. If rain is forecast, the covered cabin offers shelter but open-deck views are restricted. The cruise pairs well with a riverside walk on Kampa and a visit to the nearby café-lined courtyards for a quick post-cruise coffee.
