Wat Khao Suwannakhiri is located to the west, about 200 meters beyond Khao Phanom Phloeng. It stands on another peak in the same mountain range. The significant ancient structure here is the large, round main stupa made of laterite. The stupa features a five-tiered base, serving as a circumambulation platform, with niches for Buddha images on all four sides. At the top of the stupa, there is a clay Buddha statue in the Walking Meditation posture, similar to the one at Wat Chang Lom. Behind the main stupa, there is a round stupa encircled by a laterite wall.
