Doi Inthanon Entrance Fee

The conservation charge at Thailand's tallest peak funds one of the country's most ambitious highland restoration projects. Since the park was established in 1972, admission revenue has supported reforestation of watershed areas, maintenance of over 50 kilometers of hiking trails, and ranger patrols across 482 square kilometers of montane forest. Payment is collected at the entrance station on Route 1009, approximately 58 kilometers from Chiang Mai city center. The booth accepts cash in Thai baht; card facilities are not available, so visitors should prepare exact change or small bills. The fee structure distinguishes between Thai nationals and foreign visitors, with additional categories for students and children. Vehicle fees apply separately for private cars and motorbikes entering the park, though these are modest compared to the per-person conservation charge. What the admission covers extends beyond simple access. The fee includes use of all marked trails, from the short boardwalk at Ang Ka Luang Nature Trail to the steep ascent toward Kew Mae Pan Ridge. Visitors can stop at multiple waterfalls—Wachirathan, Sirithan, and Mae Ya among them—without additional charges. The summit viewpoint, twin pagodas, and the hilltop royal garden all fall within the single-entry system. Parking areas at major attractions are included, though some trailheads have limited spaces during peak morning hours. The park does not charge separately for photography, though commercial filming requires advance permits. Camping fees apply if you plan to stay overnight at designated sites, and these are paid in addition to the standard entry fee. The conservation charge does not cover guided services, which are arranged independently, nor does it include transportation within the park—most visitors drive their own vehicles or hire private drivers for the day. Revenue allocation follows a national parks budget model, with funds directed toward infrastructure, wildlife monitoring, and community programs in surrounding villages. The system has enabled the park to expand its ranger network and improve facilities without relying solely on government appropriations. For visitors, the practical implication is straightforward: one upfront payment provides a full day of access to one of Southeast Asia's most biodiverse highland ecosystems, from the lower-elevation agricultural research stations to the mist-shrouded summit at 2,565 meters above sea level.
