Sala Ratchaphakdi at Pha Sadet is a pavilion built as a resting place and a venue for activities, commemorating the royal grace of King Chulalongkorn on his historical visit to oversee the railway construction. Located near the historic cliff inscribed with the royal initials, the pavilion allows tourists and pilgrims to relax in the cool breeze while enjoying a close-up view of the scenic landscape of the historical railway. The surrounding atmosphere is tranquil and shaded by limestone cliffs, making this pavilion an essential stopover that perfectly blends stories of patriotism, loyalty, and the natural beauty along the railway tracks.
