[1] Formerly being the State Railway of Thailand (SRT)'s golf course, the 375-rai (60.0 ha; 148-acre) plot of land was converted into a public park for recreational activities and doing exercises of the people living in the vicinity.
Its name means "Vajira's 50", since it was made on the occasion of His Majesty King Vajiralongkorn (Rama X)'s 50th birthday in 2002 (while he was still the Crown Prince of Thailand).
At the start of bike track, there is a rental shop where visitors can rent bicycles for riding.
The town consists of Bangkok's famous buildings and tourist attractions in scaled-down version.
Besides, the southeast part of the park is also home to the Buddhadasa Indapanno Archives (BIA), also known as Suan Mokkh Bangkok, a Buddhadāsa Bhikkhu's Dharma learning and edutainment center.
