We went to Phu Kradung National Park during 9-11 February 2013 with our two of friends from Malta and 6 Thais. The reason to select the time is to be there at the end of winter time and to be during less number of visitors. This was my second trip after 10 years. We enjoyed this wonderful nature so much. We are returning to this haven during 19-21 January 2014. We would recommend it for everyone who love nature and friendships.
