The 2025 Loy Krathong festival falls on Wednesday (November 5), and the Bangkok Metropolitan Administration (BMA) will open 33 public parks across 21 districts for residents to celebrate the centuries-old Thai tradition of honouring the Goddess of the River.
The initiative aims to preserve Thai cultural heritage while allowing the public to float their krathongs in safe, nearby locations. Parks will be open from their regular opening hours until midnight (12am).
The BMA urges revellers to use krathongs made from natural materials such as banana leaves and trunks, which decompose easily. Foam krathongs are strictly prohibited. The city also discourages bread or food-based floats in public parks, as the ponds are closed systems and leftover food can cause water pollution.
To reduce waste, the BMA promotes the concept of “One family, one krathong”, encouraging families to float together.
For safety reasons, the BMA has banned sky lanterns, fireworks, firecrackers, and alcohol sales inside public parks. Violators will face legal action.
In 2024, the BMA collected 514,590 krathongs, of which 98.39% (506,320) were made from natural materials and only 1.61% (8,270) from foam, a 19.57% decrease from 2023.
Eco-conscious participants can also join the online Loy Krathong celebration via greener.bangkok.go.th between 5am and midnight on November 5. Last year, 36,832 krathongs were floated online, alongside 10,885 digital krathongs launched at four interactive sites.
The BMA said the campaign reflects Bangkok’s commitment to blending cultural heritage with environmental sustainability.
