Thailand is one of the few countries in Southeast Asia that are lucky to have rare synchronous firefly species. They are observed throughout the year, but the prime time for synchronous fireflies is during the wet season, from May to October. Some of the best places are along the Mae Klong River, in mangrove forests, and in several national parks. If you walk on a moonlit forest trail in Kaeng Krachan National Park, you can encounter thousands of fireflies lighting up in sync with each other, resembling lights on a Christmas tree.

Fireflies at Kaeng Krachan National Park and Khao Kho National Park

Kaeng Krachan National Park is the nature preserve in Thailand, located on the border with Burma. The fireflies are drawn to water, so the trails along the Pranburi River give you a good chance to see them. It's impossible to navigate through this huge park without a ranger or a guide. Luckily, there are plenty of guided tours available as well as overnight camping to fully experience the atmosphere of the jungle during nighttime. More firefly trails can be found in Khao Kho National Park is in Phetchabun Province, Northern Thailand.

Amphawa Floating Market Firefly Boat Tours

Amphawa Floating Market firefly boat tour is another way to experience fireflies in Thailand. The most popular floating market in Thailand is 31 mi (50 km) long. It is located in the Amphawa District of Samut Songkhram Province, 54 mi (87 km) from Bangkok. The guided tours often depart from the capital city. Evening boat rides departing every day from the market will let you appreciate the unique architecture and lifestyle recognized by UNESCO Asia as part of Thai cultural heritage. Fireflies flashing on the trees along the banks complete the magical atmosphere of the Mae Klong River during the Thai summer.
