When the weather starts to improve life on the Vltava River in Prague gets a little more exciting. Pedal boats are a popular summer activity on the river, with some cafes offering "drive-up" beer service for boaters. I'm told the best place to get a unique view of Prague is on a pedal boat under the Charles Bridge, but I've never done it. You can see some of those little yellow boats in this photo taken from Mánesův Bridge just down river.
