The Buddhist temple Wat Chuthathittham Saph-aram Worawihaan on Koh Si Chang (fig.) is located at the foot of Mt. Phra Chulachomklao, just across from the local pier.

On the slope above it are shrines dedicated to Chao Mae Kwan Im (fig.) and Chao Pho Khao Yai (fig.), and the white mondop just below the summit houses a Phraphuttabaht (fig.).
