The Maipo River rises in the high Andes and runs through the Cajón del Maipo before reaching the central valley and the vineyards that carry its name. In the upper canyon, around an hour from Santiago, the river drops fast over boulders and gravel beds, forming rapids that suit anything from a first-time raft trip to a splashy half-day for confident paddlers. Rafting here is one of the easiest ways to add an adrenaline hit to a city break, because everything is close enough to fit into a half or full day. Guides give a safety talk on the riverbank, hand out wetsuits, helmets and life jackets, and teach basic paddle commands before you launch. The sections used for tourist trips are mainly class II to III, with some stronger rapids in the high-water season when snowmelt boosts the river, usually from late spring into summer. Between rapids the current slows, giving you time to look up at the steep rocky walls, the cacti on the slopes and the snowy peaks above. It is a good group activity for friends, couples and teenagers, and no experience is needed. Some operators serve a barbecue or snack afterwards, and certain packages add wine or paragliding.
How it works
Your tour usually meets in the city or a pickup point, drives to the river and returns afterwards. The rafting itself typically lasts one to two hours on the water. Minimum ages and fitness requirements vary, so check them when you book, especially for younger teenagers.
What to expect
Expect to get wet. Water temperature is cold, since the river is glacier-fed, so wetsuits matter. You will paddle as a team, follow your guide’s commands and may have the chance to swim in a calm section if conditions allow. Photos are often available at the end.
Making the most of it
Wear a swimsuit or quick-dry clothing under the wetsuit, bring a towel and dry clothes, and use secure shoes that can get wet. The best months are generally spring and summer. Water levels change through the season, which affects difficulty, so ask which section is being used.
