Closest sport climbing near Guatemala City. 15-20 sport routes overlooking a volcanic lake. It is one of the most gorgeous places I have ever climbed. The view of the lake from the crag is spectacular, with an outdoor environment that is not common to most climbers. Climbing in the jungle can be exhilarating and frightening where lizards might claim your hold.
Most climbs are fairly short, 12 quickdraws being more than enough. The rock is mostly vertical or slightly less than. The rock is crimpy and not likely to break. During the rainy season you need to watch the weather because the rock can often be wet in the afternoon from showers.
It is only a short hike from a tourist town and near a chairlift that takes people up the mountain for a view of the lake. There are no entrance fees. However, if driving there might be a cost to park in the area of the lake on weekends due to the tourism. This is no more than several Quetzales. Also, the area may be crowded during certain times of the year with families and travelers visiting the lake, though the climbs usually won't be. It is secluded more often than not, but near enough to not be too dangerous.
There is a main lower and upper crag, but most of the routes start at different elevations with scrambling to traverse from one area of the crag to another. This will be explained separately for each route.
The climbing is in the town of Amatitlan, overlooking Lake Amatitlan near Guatemala City. Directions to this town can be easily obtained and is just off of CA-9 about 30 KM south of Guatemala City (Make sure your schedule allows for plenty of traffic). Once at the touristy section of the lake, head left (north) on a road that goes around the lake. Not too far, maybe a quarter mile, with houses on your right there will be a small parking area (3-4 spaces) on your left. The parking area should have a large boulder. On the right of this parking area is an obvious trail that heads up the mountain. A steep trail but takes no more than 15 minutes for fatties. Keep an eye out for vicious animals such as the nest of tracker jackers in a log half way up. The trail will take you right into the lower crag where you will find routes on the trail to the left. If you take the trail right, you will hike for another five minutes to the upper crag. The trail is easy to follow and requires some scrambling. You will pass a rock with two U bolts to help you over a short section.
