Rent a small boat and cruise around Balboa Island. Rent by the hour. Life vests provided for kids under 12.
I got a groupon to rent a boat for an hour. Normally $69/hour and I got a deal for $27/hour. My husband was happy that we weren't going on a boat 'tour' with a lot of other people. HE was the captain! One hour was the perfect amount of time for our kids (ages 2 and 4). Life vests provided for them. We cruised around Balboa island, saw a lot of other boats in the harbor, went under a few bridges, saw a few kayakers and the final family pleaser was seeing a bunch of lazy sea lions. We probably wouldn't pay full price for this boat ride, but if I ever see another deal- we are on it!
