My wife & I love to go to the Carlsbad Lagoon to tandem kayak to the back channels. Great weather, a couple hours of exercise and you feel like you're in a different world paddling through the narrow channels, fish jumping around you and an occasional crane startling you. Check Groupon for their discounts. Only about $29 for kayaking or SUP.

Love the SUP!! This weekend we rented jet skis and it was a blast! The staff is always helpful and friendly. Can't wait to go back again later this month! There are so many things to do for the whole famiky from kayaking to boating, barbecuing and hanging out with friends. A hidden gem in Carlsbad!
