The park is clean and safe which is awesome for a huge park in a very big city. You will see and you can participate in people doing yoga, working out, running and or walking. Some people just enjoying the green nature and birds and relaxing reading their phones or books. This is a great place to spend some time in a relaxing peaceful place. Time to recharge and or meditate or people watch..... Lumpini Park has it all and is good for the soul.

Next to the iconic Dusit Thani (to be re-built again, Lumpini park, as it "historic Indian name where Buddha was" name implies is a long standing historical and heritage "lung" with full of greenness since the days long gone in the midst of the BCD, easily accessed now with the MRT. A place where people walk, talk, exercise, relax and just sit down to enjoy the luxuries of greenness.

Lumpini Park is always nice if you like to spend some time walking in a less hectic enviroment while you stay in Bangkok.
Special attraction can be meeting with the lizards that live in the park and walk or swim around in it.
