Samut Prakan

Samut Prakan Province is located in central Thailand at the mouth of the Chao Phraya River, along the northern coast of the Gulf of Thailand. It is a relatively small province situated on the outskirts of Bangkok and is commonly known by alternative names such as “Pak Nam” and “Phra Pradaeng.”

 

Today, Samut Prakan plays a significant role in Thailand’s economy as one of the country’s major industrial hubs. The province is home to large industrial estates that attract substantial foreign investment, making it an important contributor to national economic growth and international business activity.

 

Covering an area of approximately 1,004 square kilometers (around 627,557 rai), Samut Prakan ranks as the 70th largest province in Thailand. The Chao Phraya River serves as its main waterway, branching into numerous canals that shape the province’s landscape. The general topography is predominantly low-lying plains, which can be divided into three main zones.

 

The first zone lies along both sides of the Chao Phraya River, where fertile land supports rice farming and orchard cultivation. The second zone, located in the southern coastal area, is influenced by seawater intrusion. During the dry season, both soil and freshwater sources become highly saline, and the area is characterized by mangrove forests, making it suitable for charcoal production and coastal resource use. The third zone covers the northern and eastern plains, which are wide and suitable for agriculture and urban development.

 

Historically, Samut Prakan was established during the Ayutthaya period, with the original city located in what is now Phra Pradaeng District. It served as a crucial naval outpost and a strategic checkpoint for maritime trade. Foreign merchant ships traveling to Siam would stop here before continuing inland, and the coastal area was fortified with strong defensive structures, including city walls and fortifications.

 

During the Thonburi period, King Taksin the Great ordered the dismantling of the old city walls of Phra Pradaeng. Later, in the reign of King Rama II, the king recognized the vulnerability of the area to potential invasions and commanded the construction of a new fortified city at Pak Nam in 1819. The construction took three years to complete and included the establishment of six major forts on both sides of the river: Phi Sua Samut Fort, Phra Chulachomklao Fort (later period), Prakarn Fort, Narai Prab Suek Fort, Prakan Chai Fort, and Nakhonrach Fort.

 

During the construction, King Rama II personally visited the site several times and ordered the building of a grand chedi on an island in the river, later named “Phra Samut Chedi.” However, the king passed away before its completion.

 

In the reign of King Rama III, the construction of Phra Samut Chedi was completed, and three additional forts were built: Tri Phet Fort, Khongkraphan Fort, and Suea Son Lep Fort.

 

In 1859, during the reign of King Rama V, Phra Samut Chedi was renovated and elevated. Additionally, a new coastal fort was constructed and named “Phra Chulachomklao Fort.” Today, many of these historic forts have deteriorated over time, with only Phi Sua Samut Fort and Phra Chulachomklao Fort remaining in relatively preserved condition.

 

At present, Samut Prakan Province is administratively divided into five districts and one subdistrict-level administrative area: Mueang Samut Prakan District, Phra Pradaeng District, Bang Phli District, Bang Bo District, Phra Samut Chedi District, and Bang Sao Thong District.

 

Travel Tips When taking a boat trip, it is advisable to prepare a hat and wear comfortable shoes. For evening boat trips, such as firefly watching tours, bringing mosquito repellent lotion is highly recommended.

 

During boat trips, visitors should avoid consuming alcohol or intoxicating substances, as these may increase the risk of accidents. When observing fireflies, it is important not to make loud noises, as this can disturb both the fireflies and local residents. Visitors should also avoid touching or interfering with the fireflies under any circumstances.

 

For safety, passengers should sit in the center of the boat, avoid leaning to one side, and wear life jackets at all times.

 

When choosing a firefly boat tour service, it is recommended to select experienced operators who are familiar with the routes and habitats of fireflies. Visitors should also confirm the distance and duration of the trip with the service provider in advance.
