Wat Kalayanamitra is just 500 meters down the road from Wat Arun and has one of the most impressive sitting Buddha Statues in Bangkok. The full name of the temple is Wat Kalayanamitr Varamahavihara. The statue is over 20 feet tall looking down at you as you enter the temple.
Wat Kalayanamitra was built in 1825 on the banks of the west bank of the Chao Phraya River, diagonally opposite where Wat Pho is.
This temple isn't found on many tourist guides so not many tourists visit here. When Wat Arun is crowded, usally on weekends, you can come to Wat Kalayanamitra which is peaceful and quiet.
There is no entrance fee to visit Wat Kalayanamitra. There are donation boxes inside the main temple if you would like to donate.
There is a pier out the front of Wat Kalayanamitra where boats can stop. No public boats stop at this pier but you can wave down a taxi boat or hire a boat from the other side of the river to arrive at the temple.
In late 2016 the exterior of Wat Kalayanamitra is going through some extensive restorations.
