If it's an active adventure you're after, you're spoilt for choice in Europe. Hike through Alpine meadows in Austria (with waterproofs to hand for the occasional rain showers); explore Croatia's dramatic coastline on a fun family kayaking trip; and wrestle the youngsters into wetsuits on a surf trip to Portugal.
For a more laid-back May half term holiday to Europe, make a beeline for the French Riviera which is starting to really warm up at this time of year - perfect weather for exploring the sophisticated seaside resorts and wandering along beautiful beaches. The Italian island of Sicily really comes into its own too in May, with comfortable temperatures and a fraction of the crowds than in summer.
