The tabletop mountains are quite isolated and mostly unexplored. Getting to the base of any tepui requires driving, flying, and hiking. The Upuigma Tepui is not a very popular route yet, as it was only first climbed in 2007. The Acopán Tepui is more well-known. Most of the designated climbs are on a south face, so the sun is out almost all day. The rocks are steep – anywhere from 1,000 to 2,000 feet tall – but roofs and ledges are easy to find.
