It is embedded into the forest, perhaps only accessible with the appropriate vehicle. I could go to Kanchanaburi with my car, but I don´t know the most convenient way to go from there to the forest monastery.
A recent WPN Publication, "Forest Path" had a chapter dedicated to Wat Dtao Dam. It seems a group of supporters bring in food regularly which is then cooked by a local workers at the monastery. There is no alms round as there are no villages nearby. The closest village is called Tung Ma Sa Yo. The monks from WPN usually come on tudong to this monastery during the hot season (April?), otherwise just a few monks would be here.
