As the largest patch of greenery in Bangkok, Lumphini Park is a haven for urbanites searching for a little exercise and fresh air. The park is dotted with ponds and lakes, and aquatic-minded visitors can rent giant duck-shaped peddle boats. These massive plastic ducks will likely be the only waterfowl you see in Lumphini Park– the rest have all been scared off by the meter-long water monitors that live in the park.
