Huai Mae Sai Waterfall : This two-tier waterfall in Lam Nam Kok National Park is known for its shallow lagoon which is perfect for swimming. The waterfall is about 20 km outside of Chiang Rai and flows all year, even during the dry season. As the trail is quite rugged, you can hire an elephant and mahout at the Ruan Mitra Karen hill-tribe village to take you the rest of the way.
You will feel so happy when you wake up in the morning and see mountains, streams, and light fog around you. You may also have a cup of coffee at the shop of the national park, which is available everyday from 8:00-17:00. At night, you can make a fire, sit around it, grill some marshmallow or meat, and sing some songs with your friends. Feel free to enjoy. However, always follow the rules of the national park when you have a camp. Don’t ignore safety and consciousness. Remember, there are lots of tourists beside of you and your group. You are not only person in the national park.
