Alicante in Spain has a couple of top attractions, like the beaches and the gorgeous mountain-top Santa Bárbara Castle. Other than that, it’s a pretty sleepy town. There are a couple of smaller attractions, which I finished in about an hour or two of walking through downtown, both featuring some of the cultural heritage of the region. The Museu de Fogueres is dedicated to one of the local festivals the Hogueras de San Juan, where they build huge figures and parade them in the streets. Museo de Belenes features nativity scene exhibitions about the life and folk stories of Christ typically shown around the time of Christmas.
Definitely not a must, but if you’re in Alicante with nothing to do, these free attractions can get you through and hour or two, and could work well with kids.
