Zipa is one of the closest and best crags by Bogota. There are tons of great 5.10, 5.11 climbs with big juggy moves and a fair amount of balance and crimp climbing. This is a great place to meet locals to climb with and will likely leave you coming back for more!
From down town Bogota hop on the Transmelenio bus to El Portal Norte. At the Portal Norte ask for the municipal bus to Tocancipa. When you arrive in Tocancipa head to the main park and ask for the bus to the Zipa climbing area. You should see some climbers waiting around especially if it is the weekend.
