Riding a wave can be a thrilling sensory experience for landlocked humans, much like hang gliding or making out with a pufferfish. Indulge in otherworldly activities with today's Groupon: for $42, you get a one-hour FlowBoard introduction and $20 store credit at Maeva Surf in Laval (a $70 value).

One of the first FlowRiders available in the area, Maeva Surf’s indoor system grants surfing aficionados a place to ride waves safely no matter the season or weather. The double FlowRider’s powerful pumps hurl water, like a schoolchild with a squirt gun, at 40 km/h along a trampoline-like surface made of tightly stretched canvas, creating two waves that accommodate a maximum of six surfers. During the introductory FlowBoard class, students absorb 30 minutes of instruction covering safety techniques and wave patterns, followed by 30 minutes on the waves themselves. Each ride on a flowboard lasts anywhere between 1 and 45 seconds depending on the level of expertise of the riders and whether they believe time is a construct of the mind. Meanwhile, students with reservations can choose to experience bodyboard instead. After class, students can browse the attached shop for beachwear and surfing paraphernalia such as Oxbow sandals ($17), a Rip Curl bathing suit ($50), and an O’Neill belt ($23).
