Lumpini Park

The first Public Park in Bangkok!!!

explaination from yahoo travel "Lumpini Park is a popular oasis, named after Buddha's birthplace. The green expanse provides a relaxing and relatively peaceful retreat from the heat and noise of the rest of the city. The best time to arrive is just after sunrise, when hordes of fitness fanatics can be spotted jogging, doing aerobics, practising tai chi, yoga or even ballroom dancing! You can hire a paddle boat, eat at one of the reasonably priced outdoor restaurants, or just take it easy under a shady tree. Admission is free."
