大涌谷温泉 蒸気造成混合泉 2号線(仙石原方面)、3号線(強羅方面)
Owakudani Onsen — steam-generated blend of Line No. 2 (Sengokuhara direction) and Line No. 3 (Gora direction)Operated by · リ・カーブ箱根
Mixed source
A strongly acidic calcium sulfate-chloride spring (pH 2.1) drawn from a steam-generated Owakudani blend. The source runs hot at 60.6 °C; at the bath the water is slightly cloudy white and carries a faint hydrogen sulfide note. With a generous 157 mg/kg of metasilicic acid it leaves skin feeling smoother, while its sharp acidity gives the prickly skin sensation that acidic springs are documented for. The water is diluted because the source temperature is high.
