This is the Thailand Buddhist National Centre at
Suan Phuttamonton (Phuttamonton Park) is a very large park just outside Bangkok in Nakorn Pathom province, best eggs a few kilometres west of Bangkok’s southern bus terminal.
Much of the park consists of open woodland with mown grass underneath the canopy, with pools, flower beds and gardens, although there are a few areas where the ground layer is uncut and insect diversity is fairly high, attracting a number of birds. Apart from birdwatching, this is a good place to have a picnic in a quiet corner of the park and it would be most enjoyable to cycle around. (Thanks http://www.thaibirding.com for the reference)
Today there was a festival there. I will come back with more details, as it’s all a bit confusing.. (for me)
Welcome back to Thailand!
