Translation of rampant in Spanish

Our main destination was not Cambodia and we had actually decided in the last minute to add this country to our trip. We were very happy about our decision and enjoyed every moment here.
The city seemed to be small but busy and many building were new. It looked like a third world country village with four and five star hotels. The infrastructure was still bad, but one could see development.
In the afternoon we went to the Cerro Catedral which is a small mountain not far (30 minutes) from the city. You can either climb up or take the chair lift. We chose the second option.
