Waterways, along with globalized trade and a sticky, papier-mâchéd crust, are what keep the world connected. Travel the world’s aquatic interstate with today’s Groupon: for $39, you get a four-person Water World excursion from Manasquan Water Taxi in Brielle (up to a $108 value). Trips depart daily at noon and return at 2 p.m.

The easygoing riverboat captains at Manasquan Water Taxi usher human cargo along the Manasquan River to a fun, aquatic-themed amusement hub. Palm-frond-adorned water skimmers pick up parties of four at the Sand Bar Restaurant, and then embark upon river-churning journeys to Manasquan Water World––a floating milieu abounding with H2O-inspired activities, such as inner tubing, seine-net fishing, and anchor juggling. While exploring Water World's charted territory, amateur Lewis and Clarks can leap above sea level on a floating trampoline, or aim water guns and unleash streams of watery ammo on liquid warlords. To keep thirsts quenched, each foursome can relish two complimentary beverages, and purchase additional libations from the on-deck cocktail bar.
