Erlangjian Scenic Area: The Heart of Qinghai Lake & 151 Base

Introduction

Erlangjian Scenic Area (also known as Base 151) is the most developed and frequently visited section of Qinghai Lake, the largest inland saltwater lake in China. Located on the southern shore of the lake in Gonghe County, Hainan Tibetan Autonomous Prefecture, this area is roughly 151 kilometers west of Xining—the distance that gave its former military code name. The site’s name, “Erlangjian” (Erlang’s Sword), comes from a distinctive sandbar that cuts deep into the lake like a blade.

For travelers who want a single, accessible point to experience classic Qinghai Lake scenery, cultural touches, and a piece of Cold War history, Erlangjian is the standard choice. This article covers geography, history, travel timing, safety, and practical decision guidance, using only verified source data and flagging gaps where information is incomplete.

Geography and the Sandbar Blade

The defining feature of Erlangjian is a narrow sandbar that extends more than 20 kilometers from the southern shore into the open waters of Qinghai Lake. From overhead, the landform resembles a sword thrust into the blue, which locals connect to the mythological god Erlang Shen.

The Erlang Shen Legend

According to local tradition, the sandbar was formed when Erlang Shen, a deity from the classic Chinese novel Journey to the West, dropped his sword while battling the Monkey King. Another version says he sliced the mountain to create the lake, leaving the sandbar as a permanent mark. This mythology gives the site a storytelling layer that complements the natural landscape.

Visitors standing at the tip of the boardwalk can see the sandbar stretch into the distance, separating a calm inner lagoon from the vast main body of the lake. The water color shifts dramatically—shallow emerald near the shore, deep sapphire further out.

Inner Lagoon and Wetlands

Behind the sandbar, a protected lagoon provides habitat for waterbirds and wetland plants. This area supports species such as bar-headed geese, brown-headed gulls, and black-necked cranes during migration and summer breeding. The wetlands also serve as a natural classroom for highland ecology, though interpretation signs are limited. Birdwatchers with binoculars can spot these species from the wooden boardwalks that line the lagoon.

Base 151: From Torpedo Test Range to Tourist Hub

Erlangjian’s second name, Base 151 (Yiwuyao Base in Chinese), refers to its secret past as China’s first torpedo launching test base. During the Cold War, the depth and breadth of Qinghai Lake were used for underwater weapons testing. The location was classified and closed to the public for decades.

Military Remnants

After the base was decommissioned and the area was opened to tourism, several structures were repurposed, and some concrete launch facilities remain visible near the shore. The juxtaposition of serene lake views with concrete military platforms creates an unusual atmosphere.

For history enthusiasts, it is worth walking the shoreline to look for old markings or retired equipment, though the site does not have a dedicated museum or interpretation center. The transformation from restricted zone to scenic park reflects broader changes in Qinghai’s tourism development.

Cultural and Religious Additions

Beyond military history, Erlangjian incorporates Tibetan Buddhist culture. A large Sea Worship Platform (Jihai Tai) and stacks of Mani stones carved with mantras stand near the main walking paths.

Pilgrims occasionally perform kora (circumambulation) around the platform, and travelers can observe this practice respectfully. The combination of mythology, military secrecy, and living Tibetan tradition makes Erlangjian more than a lake viewpoint—it is a layered destination.

Best Time to Visit

The source data lists summer and autumn as the best seasons, with a specific window of June to October for comfortable conditions.

Peak Season: July and August

July and August offer the most favorable weather: moderate temperatures (15-25°C / 59-77°F), clear skies, and the famous rape flower bloom. Rape flowers are planted in fields along the southern lake shore, producing a yellow carpet that contrasts with the blue lake. This is the classic postcard image of Qinghai travel.

However, this period also brings crowds and higher accommodation prices. Accommodation in nearby towns like Heimahe or Gonghe should be booked weeks in advance.

Shoulder Seasons: June and September-October

June has fewer flowers but still pleasant weather and thinner crowds. September and October bring cool temperatures and autumn colors along the surrounding mountains. The lake water remains visible, but strong winds can make boat rides uncomfortable. The best compromise for photographers is early September, when the yellow fields fade but the air is clear and the sky remains deep blue.

Winter and Early Spring (November to April)

Temperatures drop below freezing, and the lake may partially freeze. Many facilities in Erlangjian close or operate on reduced hours. Travel during this period is possible for those seeking solitude, but verify opening status in advance. No specific winter hours are available in the source data.

Things to Do at Erlangjian

Erlangjian offers a mix of sightseeing, cultural observation, and water activities. Below are the key experiences based on the source.

Walk the Sandbar Boardwalk

Wooden boardwalks extend from the main entrance area toward the tip of the sandbar. Walking them gives you a sense of being on the lake surface, with water on both sides. The walk is flat and easy, suitable for all fitness levels. Distances are not specified in the data but are manageable under an hour round trip at a leisurely pace.

Take a Lake Cruise or Speedboat

A pier at the scenic area offers boat rides. Options include large cruise ships and smaller speedboats. From the water, you get a panoramic view of the distant snow-capped mountains (when visible) and the full shape of the sandbar. The source data does not list prices or exact routes. Boat availability depends on weather and lake conditions; windy days may suspend operations.

Visit the Sea Worship Platform and Mani Stones

Near the entrance area, the Sea Worship Platform is a concrete structure where offerings are made to the lake. Adjacent piles of Mani stones, etched with Tibetan mantras, are a popular spot for quiet reflection. Photography is allowed, but be respectful—local custom considers the lake sacred, and pilgrims may be present.

Observe Rape Flowers (July-August)

The flower fields are not inside the paid zone but along the road leading to the entrance. Some flower fields charge a separate small fee for access (this is not verified in source data). The contrast between yellow flowers and the blue lake is the most photographed scene in the region. For the best light, shoot early morning or late afternoon.

Birdwatching in the Wetlands

The lagoon behind the sandbar is a stopover for migratory waterbirds. Bring binoculars and a field guide. Spring and early summer (May-June) offer peak bird activity. The scenic area does not have marked bird hides; scanning from the boardwalk is the best approach.

Photography Tips

The source data highlights the visual palette of Erlangjian: blue lake, yellow rape flowers, white clouds, green grasslands. Here are safe general guidelines:

• Best light: Sunrise and sunset cast warm tones on the mountains and sandbar. Midday sun produces harsh shadows but deep blue water.
• Wide-angle lens: Use a 16-35mm or similar to capture the expanse of the sandbar and lake.
• Telephoto: A 70-200mm helps isolate birds or distant boats on the lake.
• No drone information: The source data does not include drone regulations. Many scenic areas in Qinghai restrict drones near Tibetan cultural sites or military facilities. It is safest to leave your drone behind unless you confirm with park management on arrival.
• Filters: A polarizer reduces glare from the water, enhancing the blue. A graduated neutral density filter can balance bright sky and darker lake.

Altitude and Safety Considerations

Erlangjian sits at approximately 3,210 meters (10,531 feet) above sea level—high enough to cause acute mountain sickness (AMS) in some visitors, especially those arriving directly from low-altitude cities like Xining (2,200 m) or sea level. The source data advises that most travelers adapt well, but specific precautions are warranted.

Symptoms and Prevention

Common AMS symptoms include headache, nausea, dizziness, and fatigue. To reduce risk:

• Arrive in Xining or Qinghai Lake area 1-2 days before to acclimatize.
• Avoid alcohol and heavy meals on the first day.
• Drink plenty of water (2-3 liters per day) and stay hydrated.
• Move slowly; do not jog or run at Erlangjian.
• Consider carrying acetazolamide (Diamox) if you are prone to AMS; consult a doctor before travel.

Emergency Services

The scenic area likely has a medical station, but the source data does not confirm this. Major hospitals are in Xining, roughly a 2-3 hour drive. Travelers with pre-existing respiratory or heart conditions should consult a doctor before visiting any highland site above 3,000 meters.

How to Get There (General Route)

Erlangjian is about 151 kilometers west of Xining. The most common approach is via the G109 national highway, which runs south of Qinghai Lake and passes directly in front of the scenic area entrance. The drive from Xining takes approximately 2.5 to 3 hours depending on traffic and road conditions.

No public bus schedule is in the source data, but many travelers use private tours, rental cars, or buses from Xining’s long-distance station (stop intended for Heimahe or Gonghe). The exact driving time without traffic is not verified.

Who Should Visit and When to Skip

Erlangjian suits:

• First-time visitors to Qinghai Lake who want a developed, all-in-one stop with lake views, water activities, and cultural elements.
• Photographers interested in classic highland landscapes and the rape flower bloom.
• History buffs curious about China’s military-industrial past.
• Families with children, as the boardwalks are flat and restrooms are available (though not verified as clean).

Skip or lower expectations if:

• You seek pristine, undeveloped nature without crowds; consider Heimahe or Caka Salt Lake instead.
• You have severe altitude sensitivity and cannot accommodate acclimatization days.
• You are on a tight schedule and cannot afford 2-3 hours of entry time; the site is large and requires half a day if you take a boat ride.
