Translation of juerga

I understood that this was a real problem in this country and many foreigners came for sex tourism. Many bad stories had happened but my hosts were decent people. I could tell that right away.
I visited a few churches near the center and decided to climb the mountains nearby, on which there were also churches. My intention was to get a good shot at the town from above, a bird view.
Anyway, i got bored pretty fast, drank a Coconut and orange juice mix and went on. I returned my bike at four before heading again to the beach. By coincidence I met the sister of a colleague of mine.
