Talad Nam Wat Saphan (ตลาดน้ำวัดสะพาน); Talad Nam is floating market and Wat Saphan is the name of the temple
It is situated near Bhuddha Monton 1 Road (ถนนพุทธมณฑล สาย1). The temple was built a few hundred years ago and got through the era of war between Thai and Burma. It was told that the temple was burnt down by that time but 3 Buddha images were still there untouched by the fire and the enemy. Every weekend, many long-tail boats bring tourist from other floating market to making merit at this temple and also shopping local product in this floating market as well.
If you want a quick break away from Bangkok, I can’t recommend enough a trip to the floating market at Amphawa. From Bangkok, head for Rama 2 road down towards Samut Songkram and follow the signs (or take a bus/taxi/tour trip). The market itself is a hive of activity with stalls selling trinkets and souvenirs, and there are plenty of tucked-away eateries of varying quality. Highlight of any visit, though, is a trip upriver, stopping at various temples, waving to locals enjoying some riverside R&R, and then visiting the fireflies. I was skeptical at first, but they really do light up the trees (in otherwise total darkness) like shimmering Christmas tree lights. An amazing experience, even if you only do it once. There’s also plenty of accommodation in the area if you decide to make a weekend out of it. http://www.amphawafloatingmarket.com/
Unlike Other Floating Markets, This One Opens at Night. This floating market opens at night from 4:00pm to 9:00pm only on Friday thru to Sunday. I have also heard that this is where Thais go to experience their Floating Market.
