Stakkholtsgjá Canyon is a hidden gem nestled in the Icelandic Highlands, known for its magical hiking trail leading to a majestic waterfall. The canyon, part of the Þórsmörk Nature Reserve, offers a picturesque two-kilometer gravel path flanked by towering palagonite cliffs, caves, and lush vegetation. Hiking here is a blast, with mossy streams to cross and stunning photo ops along the way. Just make sure to wear sturdy boots and watch out for slippery rocks near the waterfall. Accessible only in summer, this off-the-beaten-path spot is a must-visit for nature lovers seeking a unique Icelandic adventure.
