Chiang Mai Yi Peng and Lantern Festival
The Chiang Mai Yi Peng festival is the most internationally recognised cultural-tourism event in northern Thailand, celebrated on the full moon of the second lunar month of the traditional Lanna calendar (typically November). The festival combines the release of khom loi sky lanterns with the Loi Krathong floating-lantern tradition. Mass lantern-release ceremonies at Maejo University and Nawarat Bridge draw international visitors from Europe, North America, Australia, and East Asia. The Chiang Mai provincial government, TAT, and the Tourism and Sports Ministry co-organise the event. Yi Peng is a primary demand driver for Chiang Mai’s hospitality sector, with hotel occupancy reaching 95-100% and average room rates tripling during festival week. CAAT coordinates airspace restrictions during the mass lantern releases.

Festival programmes and venues
Mass lantern releases
Maejo and Nawarat Bridge ceremonies
Mass khom loi sky-lantern releases at Maejo University (ticketed international event, ~10,000 participants) and Nawarat Bridge draw the highest global media coverage and international visitor concentration during festival week.
Cultural events
Lanna cultural parades and markets
Traditional Lanna-style processions, krathong-floating along the Ping River, and night markets throughout Chiang Mai's historic moat district attract domestic tourism and contribute an estimated $43.5M in festival-week spend.
Hospitality impact
Peak hotel and aviation demand
Hotel occupancy reaches 95 to 100% and average daily rates triple during Yi Peng week. Chiang Mai International Airport handles peak annual passenger volumes, generating CAAT temporary flight restrictions.
International reach
Global media and bucket-list status

Watchpoints 2025-2026
Aviation risk
CAAT airspace restrictions
Chiang Mai International Airport handles peak travel volumes during Yi Peng. CAAT temporary flight restrictions during lantern releases constrain flight scheduling; any escalation in restrictions could reduce tourism accessibility.
Environmental
Lantern waste and fire-risk management
Fallen lanterns cause fire-risk in dry-season Chiang Mai hills and agricultural land. Provincial authorities face pressure to limit or zone release events. Any significant fire incident risks tightened restrictions.
Demand driver
International booking lead times
Yi Peng's global bucket-list status drives bookings up to 12 months ahead. TAT's co-promotion with international tourism boards and airline route-development to Chiang Mai directly affects festival visitor-number trajectory.
