The north-western most area of Khao Sok Lake, Klong Saeng is currently a protected wildlife sanctuary. If you are looking for a Cheow Lan lake hotel here you are out of luck. The floating bungalows that were once based here have closed. Additionally, foreign visitors are no longer allowed to remain in the sanctuary overnight.
You can still visit Klong Saeng, however, and it provides the best opportunities to see some of Thailand’s most impressive wildlife. Due to its remoteness, finding a Khao Sok lake tour that guides guests through this part of the lake is difficult.
However, guests willing to spend a bit more time and money will find that Klong Saeng does not disappoint. Animals that can be seen in the wildlife sanctuary include: wild elephant, gibbons, Sambar deer, sun bear, gaur, pig-tailed macaque, langurs, and hornbills.
