Welcome to Sierra Nevada del Cocuy
It's the highest part of the Cordillera Oriental, the eastern part of the Colombian Andes. The Sierra Nevada del Cocuy contains 21 peaks, of which 15 are higher than 5000m. The tallest peak, Ritacuba Blanco, reaches 5330m.
The mountains are quite compact, relatively easy to reach and ideal for trekking, though they're best suited to experienced hikers. The starting points for these hikes are the pretty villages of Güicán and El Cocuy, both of which have scenic beauty that hikes and nonhikers alike will appreciate.
