The reopening was announced by Khun Khan National Park, under the Department of National Parks, Wildlife and Plant Conservation, after renovation work to improve safety, visitor facilities and site management.<\/p>\n
The cave was set to officially welcome visitors again from July 1, 2026, following a three-month renovation period.<\/p>\n
Located at Ban Mae Sap in Mae Sap subdistrict, Samoeng district, Tham Luang Mae Sap is a limestone cave inside Khun Khan National Park.<\/p>\n

The Tourism Authority of Thailand describes it as a relatively compact cave divided into four chambers, known as Tham Luang Thang Nam, Tham Phra Ubosot, Tham Morakot and Tham Phet.<\/p>\n
The cave has attracted attention for its unusual natural formations, including colourful mineral patterns often described as \u201crainbow\u201d curtains and striking black stalactites.<\/p>\n
Earlier reports also described the site as an unseen Chiang Mai attraction within Khun Khan National Park, highlighting its limestone formations and distinctive cave features.<\/p>\n
Reopened after safety and access improvements<\/p>\n
The reopening followed work aimed at making the attraction safer and easier to manage for visitors.<\/p>\n
CityNews reported that the renovation was intended to improve safety standards, increase visitor comfort and support better site management.<\/p>\n
The site is part of Chiang Mai\u2019s wider nature-tourism appeal, particularly for travellers seeking lesser-known attractions outside the city centre.<\/p>\n
Tham Luang Mae Sap is located in Samoeng, a mountain district west of Chiang Mai city.<\/p>\n
Travel information from tourism sources places the cave in the Mae Sap community area and within the national park\u2019s jurisdiction.<\/p>\n
