The engaging guides at Boulder Walking Tours seize the attention of curious kids and knowledge-thirsty adults alike with insights about Boulder, delving into its notable landmarks, history, and culture. The leisurely, 90-minute stroll-a-thon travels through Boulder's central pioneer neighborhoods, allowing walkers to gaze longingly at such storied buildings as the Boulderado Hotel and the Greek-style Carnegie Library. Tour groups will revisit some of the city's most notable moments—including the creation of the Pearl Street Mall and the winning bid for the University of Colorado's flagship campus—snap photos of the famous house used in Mork and Mindy, and learn about NPR's Boulder-based radio program, eTown. A visit to a drinking fountain sourced from a glacier flings imaginations back to Boulder’s Ice Age days, when early settlers first discovered that stabbing a glacier with a drinking fountain would produce water. Sundays bring free parking to several of Boulder's downtown parking garages, allowing multicar groups and old-timey wagon trains to stop without a toll.
The pool at Ocean First Divers is warmed to 88 degrees to wrap students in a watery safety blanket as they venture out of their element. As a classroom for swimming and scuba-diving lessons, the pool boasts a gradient bottom that deepens in slow increments from 4 to 12 feet. Though Ocean First Divers now trains scores of students in swimming and scuba each year, the dive center was originally founded to advocate for the ocean’s unique ecosystems. The organization was so successful in its mission that it has claimed PADI’s Environmental Achievement Award every year since the prize’s inception. Now, the dive center's creative conservation efforts include group trips to Key Largo, Fiji, Indonesia, Mexico, and the Galápagos Islands, where students get a firsthand look at why these one-of-a-kind ecosystems are worth protecting, and, alternatively, the detrimental environmental effects of litter left by Charles Darwin.
As the world's only indoor velodrome and mountain bike park, Boulder Indoor Cycling has netted considerable press attention along with a member base of passionate pedalers. An open-to-the-public mezzanine level overlooks the 142-meter track, whose corners tilt at a visually confounding 45-degree angle. First-timers can veer down the course at a moderate pace while advanced bikers gun for competition-level speeds, eyeing the current lap record of 7.690 seconds set by 2006 U.S. National Track Champion Kevin Selker. The velodrome track also encircles a mountain bike playground of wood platforms meant to mirror outdoor obstacles, such as log bridges, rock piles, and sleeping gnomes that send cycles careening over uneven terrain. Professional athletes and national champions comprise BIC's elite staff of cycling coaches. Both on the track and across the park planks, their classes acclimate cyclists of all ages to several tiers of biking techniques. Children ages 2–10 years can pilot a mountain bike without ever relying on training wheels or indebted wind gods during CycleTykes sessions. Youth programs, track cycling seminars, and adult race leagues also permit members to saddle up and whiz by at their preferred pace.
The Urban Assault Ride challenges cyclists to speed from obstacle course to obstacle course across their city during eco-friendly scavenger hunts that benefit local charities. Teams draft a road map to try to thwart the competition and be the first to complete the race, pausing at a series of checkpoints, where they must surmount such active roadblocks as slip 'n' slides, bike jousting, and reciting the Iliad in Pig Latin. The first team to conquer each challenge and cross the finish line is declared the victor, but all participants celebrate their efforts at a lively after-party stocked with snacks, beer, nonalcoholic drinks, and prizes.
Flesh-eating zombies, cannibalistic clowns, nightmarish ghouls, and haunting ghosts prowl The Frightmare Compound, ready to snatch those foolish enough to venture through its fear-infested grounds. Known as one of Colorado's oldest and largest haunted attractions, the compound houses two terrifying attractions on more than 100,000 square feet of swampland. Horrors unseen wait for new victims inside the first compound, where a haunted barn filled with terrors is the least of visitors' worries. The second attraction, the House of Darkness, was the site of a terrible massacre and lay abandoned for some time until the Frightmare staff brought it to their site. Soon after, the ghosts of those slain began roaming its halls, and clowns with a taste for human flesh found their way inside its corridors.
