Coliseum

Coliseum is the central line of the Gran Boveda, splitting the massive cave with 40 meters of relentless jugs & tufas. The line is consistently steep, but a cornucopia of great holds provides passage at a (relatively) modest grade. The line follows a vague overhanging dihedral, & an intermittent finger crack in the back provides a few key holds, though most of the climbing is on good pockets & fins. There isn't really a distinct crux, though there is a long dash between rests at around 2/3's height that is more likely to spoil your redpoint than any other section.

Begin atop a pair of large stalagmites. Stem onto the wall & head up a good tufa to an alcove. Move left & up passing many good rests, to the first of several horizontal bulges. Over this to another alcove, another bulge, & more tufa goodness. Eventually the tufas & pockets disappear. Furious liebacking leads to a tiered ledge of slopey edges. Move up & left to sinker, glue-reinforced pockets. Make a big move over the final bulge to a cool thread & a good shake. One last hard bit gains the slab.

This route stays dry when pretty much everything else is wet.

At the very top/center of the Gran Boveda cave, climbing the intermittent crack in the overhanging corner. There is a plaque at the base.

Many, many bolts to 2BA. Unless you have an 80m rope, a double or triple lower will be required.
There are no intermediate anchors, but there are some fixed biners on several bolts.
