Skateboarding—like adopting a hippo—can add new life to an out-of-season swimming pool. Give pools their second wind with today's Groupon to Ripzu Skatepark in Vancouver, WA. Choose from three options:

• For $45, you get eight skate lessons for one month in the Grom Training program (a $95 value).
• For $10, you get an all-day skate session, usable on Saturday from 10 a.m. to 9 p.m. (up to a $20 value).

Ripzu Skatepark lays out 6,400 square feet of indoor quarter pipes, a bowl, and numerous slopes for riders of all ages and skill levels. The month-long Grom Training programs blend skateboard instruction and life skills into all eight lessons. Throughout the program, burgeoning boarders kinetically coil through a 40-foot-long mini pipe before navigating the street course's wood and metal maze of rails and crossing guards doing cartwheels. The classes help build strength, agility, and balance, and Ripzu's astute instructors additionally teach riders the importance of confidence and integrity. The Grom program takes place twice a week, either on Tuesdays and Thursdays from 6:30 p.m. to 7:30 p.m. or on Mondays and Wednesdays from 4:30 p.m. to 5:30 p.m.

Explore Ripzu's olliescapes further in an all-day skate during one of Ripzu's open-rider sessions, where the park hosts daily special events geared toward various age groups and skill levels. Younger riders can street surf the pavement as their guardians lounge around in the concession area or solicit energy-drink endorsement bids on the free WiFi. The park opens at noon Sunday– Friday, and it closes at 9 p.m. on Monday, Wednesday, and Friday; 8 p.m. on Tuesday and Thursday; and 6 p.m. on Sunday.

Ripzu Skatepark's rates fluctuate throughout the week. Although Ripzu Skatepark offers its own conditional discounts, this Groupon represent the most flexible value available.
