Coliseu Rock Climbing

Follow the trail to G3. At the first major intersection, go right (signposted). In a minute you come to a clearing; the trail to Rock Master goes right (signposted) you stay left. Go uphill for a while to reach the lower end of the República Chilena sector (also signposted), which is actually the backside of the formation that forms Vale Zen.

Anyway, turn sharp right here and descend a short, steep slope with a rope handrail. Now you are at the lower end of Vale Zen, and again there is a sign here. Instead of heading into Vale Zen, go up the opposite side of the canyon following a faint trail. This leads over some rock fins and into sector Coliseu. You'll know when you arrive because there is a large limestone arch on the far end.
