Many European cities are incredibly bike-friendly compared to the UK. Why not live like a local while out there? A lot of cities offer a cycle rental service, often with a nice student discount, meaning you can zip around the city for a very small cost.
Make the most of all the exciting things you can find at local markets abroad. Buying local produce really lowers your environmental impact, as well as supporting local businesses and sampling some of the wonderful foods of the country you're in
