Last Friday was a holiday...called Hindu Saka day or Nyepi...the whole of Bali would off the electricity to make as if there is no one in the island to ward off evil spirits.
So that day me and some friends head off to Bogor to Puncak to see the tree plantations and the Safari Wildlife Recreational Park. You can just drive your car in directly inside the Safari. THe animals walked right up to u and you can feed them carrots etc. Most amazing for me was seeing the lions- all aligned together trying to get shelter from the rain.
Puncak was a beautiful sight, but Cameron Highlands is just as good. Probably won't recommend it but since you are at the Safari might as well make a trip up to see the tea plantations.
