Wat Umong Mahatherachan sits on Ratchpakinai Rd, turning right out of the cafe you walk straight ahead past the traffic lights and on to the next crossroads where you turn left into Ratchapakhinai Rd.
Alternatively, if you have visited Wat Duang Dee, then it is a short walk to the rear entrance to Wat Umong. Just turn around from the front entrance to Wat Duang Dee.

The grounds have a wonderfully quiet and relaxing feel with a variety of trees, the only things I found labeled in English. This one is a Jack Fruit.

There is a medium sized stone Chedi, with a gilded top, and a small Vihan guarded by two impressive Golden Lions.

Behind the Vihan is an enclosed garden area with a shrine, looked like a perfect meditation spot, surrounded by trees, quiet and cosy.

Walking round to the front of the Temple there are some other Engish signs, but despite one pointing to the information board, there is no English language information.
Inside this small temple you are greeted with a perfect example of the tradition for exquisite art inside the Temples. It was soon clear why this Temple is treasured as  meditation haven by those who find it.

Unfortunately I have as yet failed to find any history on this temple but hope to return soon and chat with the Monks there and will update this post when the information is at hand.
