Booba's Pontoon Tour turned out to be the perfect group outing for us. Unlike a sailboat, this is a flat-deck boat with a motor, which makes it feel really steady out on the water, and there's a top deck you can climb onto to jump off with a ladder, plus floaties and pool noodles if you'd rather just float around. You stop first at Surfside, which locals also call Nikki Beach, then head to Mangel Halto, our favorite of the two, where the boat actually parks right over a strikingly bright blue patch of water you can't reach by swimming alone. Snacks and an open bar are included, the vibe is relaxed with chill music playing, and since it's only bookable for groups of 8 or more, it never feels crowded, just you and your friends. Aim for a calm day with little wind, and book ahead since spots fill up.
