This article lists many (but certainly not all) parks and botanical gardens open to the public in Bangkok, Thailand. If you would like to contribute to this directory, please use the comment form at the bottom of this page.
ฺBangkok has several major parks (สวนสาธารณะหลัก) and botanical gardens open to the public, including:
There is a small park located alongside Saphan Taksin BTS Station. The park, which appears to be unnamed, belongs to the Department of Rural Roads (Thai: กรมทางหลวงชนบท) which is a subdivision of the Ministry of Transport.
Suan Pa Chalerm Phrakiat (Thai: สวนป่าเฉลิมพระเกียรติ) pronounced sŭan bpàa chà-lĕrm prá gìat is a small but very popular inner city park located directly under Saphan Taksin Bridge (Sathorn Bridge). It is situated between Charoen Nakhon Road and the Chao Phraya River. The immense concrete bridges carrying road traffic and the extended BTS line overhead, although imposing at first, only add to the character of the park and provide welcome protection from the sun and rain for its many visitors, some of whom play takraw (Thai: ตะกร้อ) or do aerobics. In Thai, the name Suan Pa means forestry plantation, which may explain why the park is so densely planted with trees, affording good shade to visitors at most times of the day.
Santichai Prakan Park or Santichaiprakan Park (Thai: สวนสาธารณะสันติชัยปราการ) is a small public park that lies sandwiched between Phra Athit Road and the eastern bank of the Chao Phraya River. It is in an area especially popular with low-budget western tourists and Thai university students.
In the evenings, it has an excellent view of the nearby and beautifully illuminated Rama VIII Bridge. Adjacent to the park is the brightly lit Phra Sumen Fort, and also Phra Athit Road which leads to Thammasat University.
Queen Sirikit Park (Thai: สวนสมเด็จพระนางเจ้า) is one of three public parks within close proximity of Chatuchak Weekend Market. The attractively landscaped botanical gardens cover an area of 22.4 hectares.
By BTS Skytrain: take the skytrain to Mo Chit Station and use exit number one or three. Walk through or around Chatuchak Park to Queen Sirikit Park. This should take about 10 minutes.
Chatuchak Park (Thai: สวนจตุจักร) is one of three public parks within close walking distance of Chatuchak Weekend Market. The park covers an area of 30.4 hectares including a small boating lake. The park has direct access from MRT Chatuchak Station and may be used as a shortcut to the popular Chatuchak Weekend Market.
The park has a small open air gym, a boating lake, and pedalo boats for hire. There is also a playground for young children and many paths for jogging at cooler times of the day.
Open every day from 04.30 - 21.00
Suan Santi Phap (Thai: สวนสันติภาพ) is a public park next to Ratchawithi Road, located between soi 1 and 3. Although not particularly large, the park attracts many visitors in the evenings. It is very popular with joggers and those who want to take part in the free aerobics sessions.

Benjasiri Park (Thai: อุทยานเบญจสิริ) sometimes written as Benchasiri Park, is a public park located between Sukhumvit Soi 22 and 24, next to the Emporium Shopping Complex. There are two main access gates from Sukhumvit Road and a smaller gate to one side of the park for residents and guests of the Queen's Park Hotel in Sukhumvit Soi 22.

Benjakiti Park (Thai: สวนเบญจกิติ) is a public park in Bangkok, Thailand. A former factory site of the Thailand Tobacco Monopoly, the park first opened in 2004. It has an area of approximately 130 Rai (1 Rai = 1,600 sq. m.) or 20.8 hectares and is dominated by a central lake around which a footpath and separate cycle path follow. Surrounding gardens are landscaped and maintained to a high standard, and this could rightly be described as a very attractive park.
Chuvit Garden (Thai: สวนชูวิย์) is also commonly referred to as Chuvit Park (alternate spelling: Chuwit Park) and was created in 2006. It is privately owned by Chuwit Kamolvisit (Thai: ชูวิทย์ กมลวิศิษฎ์) a controversial Thai politician and massage parlour owner.

The entrance gate pillars carry the following rather unexpected inscription:
