龍洞 (台灣)






龍洞攀岩場


龍洞，是位於台灣東北部海濱的一個自然觀光景點，行政上隸屬於新北市貢寮區，面臨東海，目前由東北角暨宜蘭海岸國家風景區管理，因其灣岸弧形有如蛟龍盤據而得名。



地形


具有龍洞岬、龍洞灣海域、以及整個東北角海岸風景區中出露最古老的岩石，和雄偉的海崖。其中龍洞岬是由砂岩所構成，龍洞灣則是頁岩與砂頁岩在海浪的侵蝕下快速後退所形成的海灣；再兩者間鋪有步道供遊客行走、賞景。全區以龍洞隧道為界，分成龍洞灣公園與龍洞南口海洋公園兩個遊憩區，遊客除了可在此聽濤觀景、游泳、浮潛、生態觀察之外，尚能從事攀岩、健行等戶外休閒活動。發達的海蝕平臺，則是觀察綠藻、蜑螺、海參、蛇尾、寄居蟹、海兔等海濱生物以及珊瑚藻、海葵、藤壺的好地方。



地質


龍洞岬鄰近海岸岩石乃北部地區最古老的地層，沈積的時代約為3500萬年，佈滿堅硬四稜砂岩，600萬年前的造山運動將海盆中的岩層推擠，隆起形成山脈。受到風化與侵蝕作用，形成了龍洞岬。[1]
