Great place, favorite among local people, especially during weekends. Bring something to eat and drink, rent a litter for 20 Bahts and enjoy in fresh air surrounded by greenery and lakes.
The best food is served on Thanon Phahonyonthin. Street hawkers are just awesome: tasty and cheap meals that can be eaten in the park. The commercial maze on the other side is a big tourists trap.
It popular with young lovers. Recently, the old railroad golf course adjacent to the park's north end was turned into a public park, with tennis courts and soccer fields available for anyone to use.
