Hẻm núi lớn Long Đàm

Longtan Grand Canyon lies in Xin'an County in the northern part of Luoyang's administrative area, and is known for its dramatic red-rock gorge landscape, a rare and striking geological feature within the region. The canyon showcases a type of narrow, steep-walled gorge formed from red sandstone, shaped over roughly 1.2 billion years of geological deposition combined with around 2.6 million years of water erosion, resulting in scenery that is considered exceptional even by broader geological standards.

Within the canyon, visitors encounter a landscape of towering rock walls, clear mountain streams, waterfalls cascading down sheer cliffs, and deep pools scattered throughout the gorge. The scale and color of the red rock formations set this apart from many other canyon or gorge attractions in China, and the site is often highlighted for its combination of geological rarity and natural beauty. Various recreational activities are also available within the scenic area, making it popular with visitors looking to combine sightseeing with some outdoor activity, particularly appealing during the warmer months as a way to escape summer heat.

Given the canyon setting, a visit typically involves a fair amount of walking along scenic trails, and visitors should wear sturdy, comfortable footwear. A full visit can take the better part of a day, particularly if combining the main canyon walk with any of the additional recreational activities on offer.

Because Longtan Grand Canyon is located outside the main urban area of Luoyang, it typically requires a dedicated day trip, and it is a good option for visitors with extra time in the region who want to pair the city's historic sites with a natural landscape excursion.
