I'm planning to visit Indonesia as a single traveler and I'm considering including a short trek in Lore Lindu National Park in central Sulawesi. The Lonely Planet Guide says it's a wonderful place for trekking and the megaliths are intriguing. It appears I can fly to Palu, meet a guide, trek for a few days, and end in Palu or Tetena, then continue on to Ranetapao or Makassar. Has anyone trekked at Lore Lindu? Any advice? Any suggestions regarding finding a guide? Any problems to avoid? Many thanks!!
