Real del Monte
This is a magical place far from the city and really worth the trip. You can visit old mines at night, the 3 beautiful churches, and the iconic rocky hills where you can do zip-lines, canyoning, hiking, ATVs, and even camping. There's also a park called El Chico where you can do basically the same activities but also mountain biking and trail walking. It's just wonderful. You should of course enjoy the pastes :).
