The Thachang Natural Spring, located in Moo Si Subdistrict, Pak Chong District, features a constant flow of water all year round. This natural spring emits water that originates from rain falling underground and is filtered through calcium carbonate-rich rocks before surfacing. As a result, the water is crystal clear with a blue-green hue and possesses alkaline properties, reminiscent of the Emerald Pool in Krabi. Visitors can enjoy swimming at no charge. For those interested in kayaking on the Lam Takong River, there’s a rental fee of 100 baht for half an hour and 200 baht for a full hour. The kayaking routes are divided into two options: a nearby route and a distant route, depending on the time you choose to purchase. Adjacent to the spring, there's a local market offering traditional foods, clothing, and souvenirs. There are tables available for sit-down meals, creating a cozy atmosphere. The natural spring is open daily from 8:30 AM to 4:30 PM, in accordance with official hours. So, during this rainy season, it's a perfect time to stop by and explore!
