When travelling with kids the biggest question is how to find places to visit so the kids will stay entertained, will have fun and also be educated and will learn new things. I think we have found the perfect place during our last stay in Spain. In San Sebastian there is a science museum called Eureka! It’s a spacious science museum with numerous interactive exhibits, a planetarium and guided activities. I am sure your kids will have as much fun as my little ones (aged 7 and 5) had. You can easily spend half a day there and to have fun along with them.
