Los Dinamos cuarto y medio is a quite recent crag (from 2014), counting up to 120 routes. It's located in theDinamos, in the south-west of the Mexico City at altitude 3400m. I will only present 32 routes of the Cueva and ¿Quien Pompó? sectors, located on the left of the crag (more sectors on the right).

The crag is north-west oriented so, sun until 1-2pm. It's a quite humide place, so you will have to avoid rainy periods.

The rock is volcanic and you can find bouldery routes but also pumpy ones. A climbing stick is very helpful to protect the first point of some routes...

Access:

- in public transport: take the metro to the Universidad stop. Then take a bus in "Terminal Cetram Metro Universidad-Anden B" asking for "Bernabé/Oyamel, ruta 128". Then you will have to take a taxi to reach the GPS point (see later).

- un car, drive up to 19.266764, -99.287212, costs 10+ 30 pesos. There, you have to take a paved road (3 curved and then cross an artificial stream to take a small path on the right in the forest (5min)). Then you reach a dirt road and follow it on the right for 400m. You will find on your left a path in the forest, leading to the crag after 6min. 25min in total.
