Yes, this will be another expensive year for travelers to Europe, but it's nice to know there are at least a few good deals left. Helsinki's summer Citybike program makes it easy to get around for only a €2 deposit that you'll get back when you return your wheels. The bright green bikes located at 26 stands around the center of the city are there for the borrowing. And, well-marked paths for cyclists make it safer to ride.
Copenhagen also has a community bike program, with 1,300 bikes available in the center of the city from May 1 through mid-December.
