Khong Island or Don Khong is the largest island in the Si Phan Don area
Introduction
Located in the Mekong River, Khong District, Champassak Province, Khong Island is noted for its natural beauty and is a growing tourist destination. Many tourists combine their visit to the island with a visit to nearby Don Det and Don Khon islands, where it is possible to view the Khone Phapheng Falls
Tourist attractions
One of the most favorite activities on Khong Island is cycling around the countryside. Both in the early morning and late afternoon when temperatures are reasonable and the light is golden, this is an excellent way to pass a few hours, though it's best to avoid the middle of the day when the heat is oppressive.
There are a few small villages scattered around the island's edge along with some interesting little temples and pleasant riverside scenery, and those with the time and money could probably get someone to arrange a trek or two, but overall the main attraction here is the gentle pace of life.
Another option is to ride 8km west to Muang Sen, where there's a marketplace and some wonderful riverside views which are fantastic at sunset.
Other options from Khong Island include trips that are easier to stage from Don Det but worth it if you're only staying on Khong Island. You can always visit Don Khon on a daytrip and visit the Li Phi Waterfalls as well as seeing the Irrawaddy dolphins and the remains of the old French railroad.
