The Ssuchunghsi Hot Springs, surrounded by mountains, are natural springs that flow up from beneath the earth. The name Ssuchunghsi, which means "fourfold river," comes from the topography of the place, being a mountainous basin surrounded by four tiers of flowing rivers that early settlers had to traverse.
四重溪因有天然溫泉自地下湧出，（古稱「出湯」），加上地處環山盆地，河川圍繞，早期居民出入均由河川涉水，步行四層灣島河川，因此稱為「四重溪」。
