Personally, i did not expect to experience such a venue with so many Thai feeling just right at the corner of my beloved city. The venue was not hard to reach, exactly next to main road of Kolonel Masturi, reachable from both sides either Cisarua or Lembang.
It's built just couple of years ago, was funded by many devoted buddhism worshipers. It has many types of temples but i trust mainly to serve Theravada Buddhism. We can stay overnight to meditate but need coordination in advance and small fee (i heard was about 50k rupiah per night). It is location for Buddhism School, also office for one of Buddhism magazine publishes in Indonesia. The main hall can be rented even for non Buddhism activities but check directly with the office prior execution.
Myself isn't a Buddhism worshiper yet i enjoyed the peace atmosphere and green surrounding. The place welcomes everyone, make sure to dress properly and wear decent slipper, some of the temple within require us to leave the footwear prior entering, i dont think wearing sneaker will be comfortable (personal opinion). I took some pictures and got dozens uploaded on my IG, it's a place i wanna visit again.
