Sintok is a small town in Kedah state, tucked into the foothills near the Thai-Malaysian border. It is home to Universiti Utara Malaysia (UUM), the country's management university, and most visitors are here on campus business rather than tourism. The university campus itself is attractively set among hills and a large lake, and the surrounding countryside is green paddy fields and rubber plantations.
There is little in Sintok proper to detain a tourist, but the area has its rewards if you are passing through. The nearby town of Changlun, about 15 kilometres north on the road to the Bukit Kayu Hitam border crossing, is known for good and cheap Thai food — a reflection of how close Thailand is. The night market there is worth a stop.
The Ulu Muda Forest Reserve, accessible from the broader Kedah region, is one of Peninsular Malaysia's largest remaining tracts of primary rainforest and home to elephants, tigers, and a rich variety of birdlife. Reaching it requires some planning and a local guide, but it is a genuinely wild area that sees very few visitors compared to Taman Negara or the Cameron Highlands.
