Complete guide to bus travel from Bangkok to Nakhon Ratchasima — schedules, prices, operators and booking tips.
Nakhon Ratchasima, known as Korat, is the gateway to Thailand's vast northeastern Isaan region and the starting point for visiting Khao Yai National Park — a UNESCO World Heritage Site home to wild elephants, gibbons and over 300 bird species.
Nakhon Ratchasima is Thailand's second-largest city by area and the commercial and transport hub of the northeast. Known locally as Korat, it sits at the edge of the Khorat Plateau and serves as the natural gateway for exploring the Isaan region.
The city's main historical site is the Thao Suranari Monument — a revered memorial to a local heroine who led the defence against a Laotian invasion in 1826. The monument is surrounded by a lively market and is a centre of local religious and cultural life.
Most travellers use Korat as a base for Khao Yai National Park, located about 30 kilometres southwest. Khao Yai is Thailand's oldest national park and one of Southeast Asia's finest — a UNESCO World Heritage site with tropical forests, grasslands, rivers and wildlife including wild Asian elephants, Asiatic black bears, gibbons and hornbills.
From Bangkok, very frequent buses depart from Mo Chit Northern Terminal throughout the day and evening, making this one of Thailand's easiest bus routes.
