Volcan Chiles is a high mountain stratovolcano at an elevation of 4.142m (13,589ft) above the sea level, located on the border of Colombia and Ecuador.
The road is called Carretera 182. This is a maintained road where a high clearance 2WD vehicle is able to travel safely at low speeds on long dry straight-of-ways, without losing control due to wash boarding, ruts, or dips. The last part of the climb, finishing on a small lake, is a slow drive even with a 4WD vehicle. The road leads halfway up the mountain. Expect foggy, rainy, cold and misty weather. Do not travel this road in severe weather conditions. It can often be treacherous, with ice and snow accumulating even in the summer, so exercise caution as you make your way. It is subject to winter snowfalls with such a high summit altitude, and the road can be closed anytime when the access is not cleared of snow. Do not take this drive if you have respiratory problems or any type of heart condition. Notorius lack of oxygen that tests the organisms and a high degree of steepness. Most people feel altitude sickness at around 2,500-2,800 meters. Extremely low oxygen for engine combustion. A major hazard of altitude is the sickness that can indiscriminately affect anyone regardless of age or fitness. The summit has about 40% less oxygen than at sea level, thus breathing is more difficult. Your pulse rate will increase and movement will be more laborious at the summit. The high elevation with its risk of altitude sickness, weather concerns, steep road grade, and overall inaccessibility make the pass dangerous and summit trips difficult.
