Prachinburi town itself is quiet, but the surrounding province has a good spread of natural and historical sights. The waterfalls are best visited during or just after the rainy season (June to October), when they are at their most impressive. The Khmer ruins and museum can be visited year-round.
Khao Ito Waterfall is a popular local picnicking spot surrounded by natural forest, with food stalls nearby. The Chakrapong Dam (Khao Ito Dam) is close by. Takro Waterfall, inside Khao Yai National Park, cascades over a series of huge rocks in a forested valley and is particularly dramatic during the wet season.
Prachinburi National Museum, behind the Provincial Hall, holds a fine collection of Dvaravati and Khmer artefacts from the ancient city of Sri Mahosot. Morakot Historical Park at Wat Sramorakot (23 km from town via Route 319) contains a group of ruins dating from the 14th to 18th centuries. Nearby, Sa Morakot is an ancient Khmer reservoir at Ban Sa Khoi village, where the original laterite sluices and Naga sculptures survive.
Wat Phra Si Maha Pho in Amphoe Khok Pip, about 20 km from town, is home to the largest and oldest Bodhi tree in Thailand, grown from a seedling brought from Bodh Gaya in India.
