The ocean shapes our coasts with currents, tides, waves, and giant sea monsters with an affinity for building sand castles. Spy the sea monster’s masterwork with today's Groupon: for $149, you get a two-hour WaveRunner tour of the La Jolla coast from Seaforth Boat Rentals in Mission Bay. Tours are held on Friday, Saturday, and Sunday and depart at 8 a.m. (Extra tours will be added if necessary.)

Seaforth guides water riders on scenic WaveRunner tours along the La Jolla coastline, giving guests the mobile sensation of a flying fish and the wind-blown hair of a zooming porpoise. Before jetting off into the ocean, the staff helps acquaint first-timers with their Yamaha WaveRunner VX110 aqua-steeds.

With the thrum of 110-horsepower motors and the roars of seagulls in their ears, tourists get watertop views of sheer cliffs, landlocked humans, and the calm waters of the cove. Water jockeys can bring along one spare friend to act as passenger as their hydrocraft makes wave donuts, searches for surface treasure, and chases after accidental ghost ships.
