Seeing the world by bike beats seeing the world by spaceship, as space shuttle tours are often ruined by lack of oxygen and guides who deliver facts by shouting them in Neptunian. Enjoy the calm of an oxygen-enriched trek with this Groupon.

$15 for $30 Worth of Rental Bikes and Outdoor Gear

This Groupon is valid for bicycle rentals, bicycle-vehicle rentals, and other outdoor-gear rentals, such as a cruiser ($8/hr.) or tandem bike ($15/hr.). See the full lists of available rentals at the Pismo Beach locations on the Beach or scenic Highway 1. Armed with maps, helmets, locks, and lists of noteworthy sites, riders pile into surreys ($20/hr.), deuce coupes ($20/hr.), or chopper-style cycles ($10/hr.) and embark on treks across miles of pristine beach, atop a 1,370 foot wooden pier, or through a shop-lined downtown district. Along the waterfront, riders can stop to stare into one of the many tide pools, dolphin watch, or frolic among more than 50,000 monarch butterflies in the Monarch Butterfly Grove about a half a mile south of the beach. Wheel Fun Rentals recommends wearing comfortable clothes and shoes and bringing along sunglasses, sunscreen, and a camera.

Prices vary by location.
