Wonderful!!! we did a round trip (with group). We were there for 15 days, we were advised against August because of the rainy season. But well, nothing as changeable as the weather shall we say. Only on the last day we had some wind and rain at the end of the day, but otherwise all days were dry and (nice and) warm.— This text is automatically translated to English
