Khao Chang Phueak, Thong Pha Phum (Kanchanaburi)

Kanchanaburi’s most dramatic ridge is famous for its narrow “blade” section and fog-filled valleys on cold mornings. This day hike requires a steady head for heights and is managed by the park with strict daily quotas for safety and conservation. Expect steep ups and downs, exposed sections, and a top-out that rewards you with layered mountain panoramas. Book early in cool season, especially for weekends, and bring sun protection and water alongside a warm layer for the chilly start.
