Wat Saket is not generally considered a notable temple in its own right, and most visitors come for the Golden Mount. However, it is interesting for its long history and its use as a cremation and burial site for so many people.
To the reach the top of the Golden Mount, you must ascend an exhausting 318 steps. On a clear day, the view from the top includes old Rattanakosin Island and the rooftops of Bangkok.
Just north of Wat Saket is where you can catch canal boats back to the town center, Siam or further up Sukhumvit.
