This 142-acre park is centrally located and is the most important park in Bangkok. There are manicured gardens, an artificial lake, and plenty of lovely trees offering decent shade. The King Rama VI Monument is at the park’s entrance.
There is a 2.5 km running path around the park, with distance markers. This is one of the most popular places to run in the city. One bonus for lunchtime runners: there are showers and lockers available for rental. Keep an eye out for monitor lizards!
