Stakkholtsgjá canyon, nestled in Iceland's rugged Þórsmörk region, offers a captivating adventure for visitors. Accessibility is challenging, demanding a sturdy 4x4 vehicle for the F-roads and river crossings to the trailhead, thus guided super jeep tours are highly recommended for safety and convenience, especially for those unfamiliar with highland driving. The canyon is typically only accessible during the Icelandic summer, from late June to mid-September, due to severe winter conditions closing roads. While the hike into the canyon is free and usually takes 1-2 hours, the primary cost lies in transportation, either a costly 4x4 rental or a guided tour, which typically ranges from $150-$250+ per person for a full-day Þórsmörk excursion. Visitors should plan for a full-day commitment to reach and explore the area, and come prepared with waterproof gear and sturdy hiking boots, as exploring the narrow gorge to reach its hidden waterfall often involves wading through shallow, potentially slippery water.
