Lumphini Park, established in the 1920s by King Rama VI, is Bangkok's first public park, spanning 142 acres in the heart of the city. It offers a serene escape with lush lawns, an artificial lake, and winding paths, ideal for activities like jogging, paddle boating, and observing wildlife such as monitor lizards and over 30 bird species. The park also houses Bangkok's first public library and hosts cultural events like the annual Concert in the Park. Accessible via Sala Daeng BTS Station or Silom MRT Station, Lumphini Park is open daily from 4:30 AM to 9:00 PM, providing a tranquil retreat amidst the urban landscape.
