The caves can be reached by taking the Au Luk-Laem Sak route for about two kms. Then take a right turn to the Bo Tho pier then transfer to a rented boat along the Ta Prang canal. About ten minutes after passing a mangrove swamp will be the Tham Lod Tai, which is a cave beneath a limestone hill with a stream flowing through narrow passages. The main attractions are beautiful stalactites and stalagmites. The Tham Load Nua is a large cavern with meandering passages longer than at the Tham Lod Tai. They are navigable only during low tide.
