This is an amazing place, hidden away from sight right in the centre of the city. There is one big wall which has a great 30-35 foot traverse, and about 9-10 climbs. The climbs are all about 25-30 ft. high and the grades range from 5.8 to 5.11d. Two climbs have pre-placed pitons and can be led, but the others all have to be top-roped. There is another smaller wall on the right, which has two more traverses. Newcomers always feel that the grading is a little severe but once you get used to the climbs they seem a little easier.
Access is free, but it's best to inform the guards around that you'll be climbing. Also, since the rocks are in the jungle, women climbing there alone is an absolute no-no. Be sure to bring something to cut away the thorns!
