We will be in Arenal at the Observatory Lodge for 4 nights around New Year with 6 adults and 5 kids ranging from 13 to 7 years old. We are looking for the best excursion ideas for our age range that won\’t mean more than 2-3 hours in the car to get there and back. Not interested in white water rafting but other adventure activities safe for the little kids would be good. All ideas welcome.
