Marbella is an iconic vacation destination in Spain, full of spectacular beaches and kid-friendly fun. It is quite developed, so this isn’t a location for those who seek remote isolation, yet the lush vegetation still lends a sense of serenity. Day trips to cultural sites like the Alhambra are possible, but most families prefer just to relax for days on end at one of the kid-friendly luxury resorts that dot the area. The best properties have all the amenities you’d expect onsite, and the international clientele is a highlight, as families from all over the world can watch their children play together.
