• Visit Las Termas de Cauquenes and enjoy a nice thermal bath from naturally hot springwaters. Located 31 km east of Rancagua, the surrounding area also offers pretty trails for easy hiking [2].
• Reserva Nacional Río Los Cipreses is a national park east of the city, towards the Andes. Great for overnight camping. Be sure to arrive early however, as you won't be able to get in after the 6pm closing time.
• Take a tour of the now defunct mining town of Sewell (now a UNESCO World Heritage Site), situated right on top of El Teniente, the largest underground copper mine in the world. Private tour agencies can take you to the town, the mine, and back [3]. If going there by car, keep in mind they only let vehicles manufactured after 2001 through.

• Paseo Independencia - The city's commercial backbone is also a nice pedestrian avenue to eat, shop, and stroll. Beware however during the Christmas holidays, when the atmosphere gets dense and pickpockets become ambitious.
• Plaza de los Heroés - Located at the east terminus of the Paseo Independencia, this central plaza renovated in 2003 is a nice place to relax anytime. Avoid gypsies who will literally tease the cash out of your pockets.
