Tucked between the MacGillycuddy Reeks and Purple Mountain, the Gap of Dunloe is a stunning glacial valley in Ireland that was formed over 25,000 years ago. Visitors can explore the area on foot, by bike, or with a jaunting car tour. The narrow road through the Gap can get crowded, so driving is not recommended. The picturesque lakes, jagged mountains, and rich history make the Gap of Dunloe a must-visit spot for nature lovers and history buffs alike.
