The Bolivar Ferry has been entertaining kids for more than 70 years. Shuttling back and forth between Galveston and the Bolivar Peninsula, the boats often attract frolicking dolphins as escorts. You can head to the back with some bread or chips and feed the seagulls by hand as they politely hover near you. You'll pass the sunken remains of an experimental World War I concrete ship (how did that idea never catch on?), cruise past giant container ships heading for the Ship Channel, feel the wind and sun on your face and smell the saltwater (and, unfortunately, the Ship Channel). Each crossing lasts a kid-friendly 20 minutes, long enough to entertain without getting boring. And it's free! Best tip: Leave your car and just walk on, thereby avoiding the sometimes lengthy waits vehicles endure.
