Practical information about Wat Phra Si Ariyabot (or Si Iriyabot)
It is located in the Historical Park area called Aranyik (or Arinyik regarding the spelling on the signs but again the spellings differ). There are two entrances, one on Ratchadamnoen 2, the entrance where the Information Center is (this is also where the bus drops you off if you ask to go to the Historical Park) or in a oblical street (GPS N16°29'51.92" E99°30'57.00"). We do not know the name of the street but it is indicated very clearly on Ratcahadomnoen 2 when you come from Kamphaneg Phet.
Entrance fee for this part of the park:
100 THB or 150 if you take a ticket for the two areas.
You can rent bikes at the entrance for 30 THB. It is also possible to enter with a vehicle, including bicycles, for a fee of 10 to 50 THB depending on the vehicle.
