If you are looking for a family vacation where everyone can take part then Costa Rica is the spot. Having run adventure trips for the last 15 years we have had everyone from toddlers to great grandparents. Families always want to know if their kids can take part in the adventures and at what age limit are they not allowed. This can be devestating news to a child to see their older siblings zipline and then told they are not allowed. Lucky for you most all companies in Costa Rica have child harnasses, lifevests, surfboards, and all the gear to allow children as young as four to take part in adventures.
