Best Hiking Trails in Thailand: National Parks, Mountains & Jungle Treks

Thailand's hiking and trekking infrastructure has improved dramatically, with national park trail systems, guided trek operators, and jungle camping options now matching many established hiking destinations. The best hiking areas: Doi Inthanon National Park (Chiang Mai province) — Thailand's highest peak (2,565m), with well-maintained trails through elfin forest and montane ecosystems; the two Royal Pagoda trails are gentle 3km walks; the summit trail is a straightforward half-day hike. Khao Yai National Park — UNESCO World Heritage Site with excellent jungle trails; hornbills, gibbons, elephants, and occasionally tigers; guided trails are essential as this is genuine wilderness. Doi Ang Khang (Chiang Mai/Chiang Rai border) — cooler temperatures and mountain agriculture make this a distinctive northern trekking base. Erawan Falls (Kanchanaburi) — a 7-tier waterfall trail through jungle; extremely popular but genuinely beautiful; swimming at each tier. Khao Luang National Park (Nakhon Si Thammarat) — an underrated south Thailand hiking area with excellent waterfalls and fewer tourists. For multi-day treks: the hill tribe treks from Chiang Mai and Chiang Rai (2–4 days) remain a compelling way to see the mountainous north; choose operators who work directly with villages and practice responsible tourism principles. Budget ฿1,500–3,500 per day for guided trekking; national park entrance fees are ฿100–300 for foreigners.
