I spent tourism in beautiful thailand. I go to tourism khao yoi. when I go there in my opinion , khao yoi is amazing and is nature beautiful . Khao Yai National Park, it is classified as tourist attractions and an abundance of wildlife and a variety of tree species, which is located in the District of Nakhon Ratchasima province. To which Thailand’s first National Park is also its second largest, and certainly one of its best! Khao Yai National Park spreads to four different provinces with the bulk of its 2,100 square kilometers in Nakhon Ratchasima. The park has a variety of terrains from deciduous forest to savannah and houses some 3,000 species of plant. Wildlife in the park is as varied as its terrain and it is home to around 200 wild elephants. The park also houses tigers, gibbons, bears, deer, bats, wild pigs, and a major bird population including a wide variety of hornbills. In my opinion, I think we should go in winter or rainy season. In the winter we will be exposed to the cold weather but it may be hot and sunny during the day, which in the rainy season, we can enjoy the greenery of the trees. Private I want to travel in the rainy season, because it makes me feel refreshed with a drizzle, and good atmosphere. what should be need portable . Backpack Maps, tooth brushes, Sun cream.
