Location & Transportation

Sanyuan Dong (Trinity Cave) sits quietly within the Huaqing Palace scenic area, nestled at the foot of Lishan’s West Silk Ridge in Lintao District, Xi’an. To get there, you can take a taxi or bus to Huaqing Pool (a major landmark), then walk uphill for about 10 minutes—you’ll spot Sanyuan Dong right after the West Gate entrance. If you’re coming from downtown Xi’an, it’s a 40-minute drive, and the scenic area is well-signposted, so you won’t miss it.

Natural Scenery: Mountains & Fresh Air

Sanyuan Dong is surrounded by lush forests and towering peaks, making it a perfect escape from the city. The cave itself is carved into a cliffside, with vines and moss framing its entrance—it feels like a hidden gem. In spring and summer, the air here is crisp, and you might even hear birds chirping or leaves rustling in the wind. For hikers, this spot marks the start of Lishan’s trails, leading to higher peaks like Laojun Temple.

Cultural & Historical Vibes

What makes Sanyuan Dong special? It’s not just a cave—it’s a Taoist sacred site. Inside, you’ll find three quiet chambers honoring “Heaven, Earth, and Water” deities. The first chamber holds the Jade Emperor (Yu Huang Da Di), the second is for the Earth God (Land Lord), and the third is dedicated to Great Yu, the legendary flood tamer. Each altar is simple but peaceful, with incense swirling in the dim light. Even if you’re not into religion, the carvings and old-timey vibes are worth a peek.

Practical Tips: What to Bring

The path to Sanyuan Dong is rocky but manageable for most visitors. Wear comfy shoes! There’s a small rest area nearby with benches, and bathrooms are available near the Huaqing Pool entrance. Bring water, especially in summer, and keep an eye on kids near the cliff edges. Tickets for Huaqing Palace include access to Sanyuan Dong, so no extra cost—just check the opening hours (usually until 5–6 PM).

Off the Beaten Path

Unlike busy spots like the Terracotta Army, Sanyuan Dong stays pretty chill. Most tourists rush to Huaqing Pool or the hot springs, leaving this cave as a local secret. If you love photos, visit early morning or late afternoon. The sunlight filters through the trees, creating a magical glow on the cave’s stone walls. Plus, the views of Huaqing Pool from the hilltop are stunning!

A Relaxing Experience

Wandering through Sanyuan Dong feels like stepping back in time. The cool air inside the cave contrasts with the warm sun outside, making it a great mid-hike break. Locals say the spot brings good luck, so some people leave tiny tokens of gratitude. Whether you’re into history, nature, or just想找a quiet place to think, Sanyuan Dong has that “wow, I found a hidden treasure” feeling.

Pro Tip: Pair your visit with a soak at Huaqing’s hot springs afterwards—it’s the ultimate Xi’an day trip!
