About Silfra
史费拉 (Silfra) 是辛格维利尔国家公园 (Þingvellir National Park) 内的一条淡水裂缝，北美和欧亚板块的交汇处。这些水是来自朗格冰川的冰川融水，经过多孔熔岩过滤 30 至 100 年，然后才呈现出晶莹剔透、能见度高达 100 米的水。水温为 2–4°C，需要穿着干式潜水服，但在两个大陆板块之间浮潜或潜水的体验是完全独特的。史费拉 (Silfra) 一直被评为世界顶级潜水胜地。
🐉 Legends of Silfra
Silfra has been part of Icelandic folklore for generations. Local tales speak of hidden people (huldufólk) and other supernatural beings who inhabit the area. According to tradition, this place deserves respect and visitors should be mindful of the ancient spirits who call it home.
📖 History
The fissure was created by the separation of the two tectonic plates, which drift apart by approximately 2 cm per year. The water in Silfra is glacial meltwater from Langjökull glacier that has been filtered through underground lava rock for 30–100 years, giving it extraordinary clarity with visibility up to 100 meters. Water temperature stays around 2°C year-round.
