Motorcycle buffs will be intrigued by the strange motorcycle samlors peculiar to Ko Si Chang, three wheeled motorized rickshaws with outrageously powerful automobile or Harley Davidson engines. These once roamed the streets of Bangkok but were banished to Si Racha years ago. They can be hired for about 60 baht an hour to take visitors on a tour of the island.

   
Si Chang is a rock island with no natural source of spring water. Therefore, they need huge water tanks to store the rain water for use all year round. Water tanks, for example, are built under every building in the temple. When it rains, the water will flow from the roof down the rain pipes to the tube which flows directly to the water tank underneath. When the top water tank is full, the water will flow over to a pipe which goes to the one below, until all water tanks are full. Then the excess water will be released to the sea.

   
Wat Thamyaiprig started in 1970 a spartan, solitary abode at a limestone cave up the mountain on Si Chang Island. The temple grew as the abbot's fame as a meditation teacher attracted the religious-minded to enter a monastic life and learn meditation under his guidance. The temple now accommodates 23 monks and 22 nuns from various professional backgrounds.

   
Situated in the Gulf of Thailand 12 km offshore from Si Racha, its proximity to the shipping lanes has made it a convenient anchorage for dozens of barges which transship their cargoes to lighter boats for the trip up the Chao Phraya to Bangkok. Boats to Ko Si Chang leave hourly from the pier in Si Racha, taking about 40 minutes to make the trip.
