The border then moves eastward across the northern part of Peninsula Malaysia's Main Range (Malay: Banjaran Titiwangsa) along the watershed of Malaysia's Perak River and Pergau River (in Kelantan) on one hand, and Thailand's Pattani and Sai Buri Rivers on the other until it reaches Jeli Hill (Malay: Bukit Jeli). Among the mountain peaks located along this section of the border are Kobeh Hill (Malay: Bukit Kobeh), which is the southernmost point of Thailand, and Ulu Titi Basah.
