The area is an artificial reservoir created by the construction of the Sirindhorn Dam, which was completed in 1971.
It is colloquially known as 'Pattaya of Isan' because the landscape serves as a surrogate beach resort for the landlocked Northeast region of Thailand.
The floating raft restaurants are frequently tethered together, forming long chains that extend deep into the reservoir during peak seasons.
The reservoir's water is managed by the Electricity Generating Authority of Thailand (EGAT) for both irrigation and power generation.
Pattaya Noi is a popular freshwater recreation area located on the shores of the Sirindhorn Dam reservoir in Ubon Ratchathani province. The area is locally referred to as the 'Pattaya of Isan' due to its sandy banks and extensive water-based leisure infrastructure. Visitors primarily utilize floating bamboo rafts (pae) that are moored along the reservoir’s edge, often equipped with dining tables and sunshades. The reservoir serves as part of a major hydroelectric power project, creating expansive water vistas surrounded by forested hills. The site is a primary destination for regional domestic tourism, particularly on weekends and public holidays. Water activities include swimming in the reservoir, pedal boat rentals, and motorized boat tours of the surrounding shoreline. Numerous independent vendors line the bank, offering local Isan cuisine, fresh grilled river fish, and papaya salad. The water levels fluctuate significantly depending on the season and dam operations, affecting the width of the available shoreline.
The elevated viewing points along the road before descending to the shore provide a panoramic perspective of the raft clusters against the reservoir backdrop.
Bring your own towels and change of clothes if you plan to swim in the reservoir.
Choose a raft located further away from the main entrance if you prefer a quieter environment.
Confirm the availability of life jackets with your raft operator before entering the water.
Avoid visiting during the height of the rainy season when water levels may submerge the typical seating areas or make the banks muddy.
Modest swimwear is recommended; avoid overly revealing clothing when dining in the floating raft communal areas.
