The Circuito Chico was paved in 1936 as a 60-kilometer mountain road threading Bariloche's western shore, built to connect scattered homesteads and alpine hotels along Lago Nahuel Huapi. Today it remains one of Patagonia's most trafficked scenic loops, drawing more than 300,000 visitors each year who arrive by tour bus, rental car, and increasingly by bicycle. The route climbs gently from the base of Cerro Campanario at kilometer 17.5, where a chairlift carries hikers to a 1,050-meter summit offering 360-degree views across six surrounding lakes and the serrated spine of the Andes. Cycling the Circuito Chico reveals detail that vehicle passengers miss: the smell of wet coihue bark after morning rain, the shift in light as the road curves from open shoreline into dense lenga forest, the texture of volcanic basalt layered into roadside cliffs. The elevation gain is modest—150 meters over the first 10 kilometers from Bariloche's hotel zone—but the wind off Nahuel Huapi can gust to 40 kilometers per hour, especially in the afternoon when thermal currents rise from the lake. Most guided bike rental tours depart between 9:00 and 10:00, allowing riders to complete the outbound leg before midday gusts pick up. The chairlift at Cerro Campanario, installed in 1970 and refurbished in 2018, ascends 100 vertical meters in four minutes. Riders disembark onto a wooden platform surrounded by ñire and araucaria trees, then follow a 200-meter boardwalk to the summit observation deck. From here, Lago Moreno Este lies directly below, its turquoise shallows contrasting with the deep indigo of Nahuel Huapi to the north. On clear days, Cerro Tronador's triple summit is visible 40 kilometers southwest, its permanent snowfields feeding glaciers that calve into Lago Mascardi. The deck is equipped with interpretive plaques identifying 18 named peaks, seven lakes, and the route of the old railway that once ran from Puerto Pañuelo to Llao Llao. Bike rental operators based near Cerro Campanario typically provide hybrid or mountain bikes with 21-speed gearing, helmets, repair kits, and route maps marked with rest stops at Punto Panorámico (kilometer 8) and Playa Bonita (kilometer 12). The half-day format—standard across most circuito chico bariloche bike rental offerings—covers 25 to 35 kilometers depending on turnaround point, with support vehicles trailing groups of six or more. Riders return by 14:00, before afternoon traffic peaks and the prevailing westerly wind strengthens.
