Ice is nothing more than water that won’t let people swim in it. Teach stubborn liquid a lesson with today’s Groupon to Harbor Village in Half Moon Bay. Choose from the following options:

• For $20, you get $40 worth of Christmas trees, wreaths, and stands.
• For $8, you get ice-skating with skate rental for two (a $16 value).
• For $16, you get ice-skating with skate rental for four (a $32 value).

Ice-skating is held outdoors on Saturday, December 10 and Sunday, December 11.

Harbor Village enhances its year-round shopping and coastal ambiance with an artificial ice-skating rink and noble firs for purchase. The rink maintains a chilly façade without the aid of electricity-devouring refrigeration units, making the setup as eco-friendly as a tree-snuggling polar bear. The surface of the faux ice speeds skaters along with a glide-enhancing liquid coating that leaves rinks 10%–15% slower than an actual frozen pond. Alternatively, families can head to the tree lot to pick up the right size fir with which to tickle the living-room ceiling, whether 4 feet ($23) or 10 feet ($121). Mixed noble wreaths ($19 for 24”) spruce up doors and walls, and cleated wooden stands ($8 for a 40” stand) hold trees steadfastly upright.

Beneath the vaulted steel and glass of Harbor Village’s ceilings, 19 shops and restaurants carry on brisk holiday commerce. Bay windows increase the open, airy ambiance, evoking the feeling of a 19th-century seaport with eclectic rooflines, mixed shingles, and gambling pelicans.
