# Longtan Lake (Simian Mountain) – A Danxia Lake with Wild Monkeys

Longtan Lake (Dragon Pool Lake) sits at the heart of the Simian Mountain National Scenic Area in Jiangjin District, Chongqing. It is an alpine barrier lake formed over millennia by geological shifts and the natural damming of mountain streams. At roughly 900 meters above sea level, it offers a cool retreat from the summer heat and a chance to see wild macaques roaming freely along the shore.

The lake is known for its dramatic juxtaposition of deep emerald water against towering red Danxia cliffs, earning it the nickname of a living landscape painting. This guide covers what makes Longtan Lake unique, how to plan a visit, and what to expect when you arrive.

## Location and Geography

Longtan Lake lies in the southwestern mountains of Chongqing, close to the borders of Guizhou and Sichuan provinces. It is part of the much larger Simian Mountain Scenic Area, a 213-square-kilometer reserve famous for its lush forests, waterfalls, and Danxia landforms.

The lake itself is a dammed body of water fed by rain and mountain springs. Its elevation of around 900 meters means the air is noticeably cooler and cleaner than in Chongqing city, contributing to its reputation as a “natural oxygen bar.” The lake’s eastern shore abuts the trailhead for Wangxiangtai Waterfall, one of China’s largest single-drop waterfalls, making it convenient to visit both in one day.

The surrounding terrain is rugged, with steep red sandstone cliffs rising directly from the water. These cliffs are part of the Danxia landscape, a UNESCO-recognized landform characterized by red sedimentary rock and unusual erosional shapes.

The forest cover is exceptionally dense, with over 95% of the area forested, mainly subtropical evergreens, bamboo groves, and ferns. This thick vegetation supports a diverse ecosystem, including the troops of wild macaques that have become a major attraction.

## Highlights of Longtan Lake

### Danxia Lake Scenery

The most photographed view at Longtan Lake is the reflection of the red Danxia cliffs in the emerald water. The contrast is most vivid on clear mornings when the lake is calm and the sun lights up the cliff faces. The cliffs themselves are often striated with bands of different minerals, creating natural patterns that locals call “rock paintings.” A boat ride across the lake gives you the best vantage point to see these formations and the way they change with the angle of light.

### Natural Ecological Monkey Garden

Wild macaques (Macaca mulatta) have lived in the forests around Longtan Lake for generations. Unlike monkeys in some Chinese parks that are forced to perform, these monkeys are free-ranging and accustomed to human presence only because of frequent visitor traffic. You can often see them grooming each other on branches overhanging the water or scrambling along the shore in search of food.

Interaction is permitted but caution is advised — the monkeys can become aggressive if they think you have food. It is safer to watch from a distance and avoid carrying open snacks.

### Boating on the Lake

Traditional painted boats, similar to those used on the Li River in Guilin, operate on Longtan Lake. The boats are usually covered and seat 10–20 people. The journey takes you along the main part of the lake, passing the Danxia cliffs and under the shadow of the forest.

On misty days, which are common in spring and autumn, the lake takes on a dreamy quality, with the cliffs appearing and disappearing in the fog. The boat ride is the primary way to reach the Wangxiangtai Waterfall trailhead if you are not hiking along the shore.

### Gateway to Wangxiangtai Waterfall

Longtan Lake is the closest scenic point to Wangxiangtai Waterfall, a massive 152-meter high cascade that is often billed as “China’s No.1 Waterfall of its kind.” You can either walk from the lake along a forest path (about 20 minutes) or take a boat to the landing nearest the waterfall. The roar of the water becomes audible long before you see it, and the spray can be felt from viewing platforms. Combining the serene lake with the powerful waterfall makes for a well-rounded nature outing.

### Wolong Ditch Exploration

Wolong Ditch (Sleeping Dragon Ditch) is a narrow valley that runs into the main lake area. It features a clear stream, small waterfalls, and a trail that winds through primitive forest. The hike is relatively easy, taking about 1 to 2 hours round trip, and offers a closer look at the biodiversity of Simian Mountain.

You may see ferns, moss-covered rocks, and if you are lucky, some of the smaller wildlife like squirrels or birds. The trail is unpaved in sections and can be slippery after rain, so proper footwear is necessary.

## Practical Information for Visitors

Longtan Lake is part of the Simian Mountain Scenic Area, which charges a combined entry fee that covers multiple attractions including Wangxiangtai Waterfall, Land Rock, and others. As of the latest publicly available information, the adult ticket is around 90–110 RMB, but prices can change without notice, and discounts may apply for students, seniors, and children.

The lake itself does not require a separate ticket once you are inside the main scenic area. Boat rides are an additional cost, typically 30–60 RMB per person depending on the route and duration.

The scenic area is open year-round, but the best time to visit is between May and October when the weather is warm and the forest is fully green. July and August are the peak months for escaping the Chongqing heat, though they also bring the highest crowds and occasional rain. Spring (March–April) and autumn (October–November) offer clearer views and cooler temperatures, with autumn foliage adding color to the cliffs.

Getting to Longtan Lake from central Chongqing takes about 2.5 to 3 hours by car or bus. The most common route is to take the G93 expressway toward Hejiang and then follow local roads into the Simian Mountain area.

Public buses run from Chongqing’s Chenjiaping bus station to Jiangjin and then to the scenic area, but a direct bus may be available during peak season. Once inside the park, shuttle buses connect the main parking lot to Longtan Lake and other attractions.

Accommodation options range from basic guesthouses near the park entrance to a few resort hotels inside the scenic area. Staying overnight allows you to experience the lake in the early morning when the monkeys are most active and the boat traffic is light. There are also local farm stays (nongjiale) that serve home-style Chongqing dishes.

## When to Visit Longtan Lake

The lake is accessible year-round, but the experience varies significantly by season. Spring brings flowers and mild temperatures, but rain is common, and the lake may be shrouded in mist.

Summer is the most popular time because of the cooling elevation — temperatures are typically 6–8°C lower than downtown Chongqing. However, weekends and holidays can be crowded, and the monkeys may be more aggressive due to higher food availability from tourists.

Autumn is arguably the best season for photography. The monsoon rains have ended, the air is clear, and the forest turns orange and gold. Winter sees fewer visitors, and the lake takes on a still, quiet atmosphere. Snow is rare at this altitude, but the bare trees offer a different perspective of the Danxia rock formations. If you want to avoid crowds entirely, a weekday in late October or early November is ideal.

## Who Should Visit and Who Should Skip

Longtan Lake suits travelers who enjoy moderate nature walks, boat rides, and wildlife viewing without strenuous hiking. It is a good choice for families with children, as the monkey interactions are entertaining for kids, and the lake trail is flat and easy.

Photographers will appreciate the Danxia reflections and the chance to capture wildlife in a natural setting. It also works well as a short stopover on a longer trip to Simian Mountain or to the nearby attractions in Jiangjin.

The lake may disappoint adventure hikers looking for challenging terrain. The main trails are short and well-maintained. If you want more strenuous activity, consider adding the hike to the top of Wangxiangtai Waterfall or exploring the deeper valleys like Land Rock (Wangxiangtai area). Also, visitors sensitive to crowds should avoid summer weekends when the lake area can fill with tour groups.

## Safety and Wildlife Considerations

Altitude is not a concern at 900 meters; no visitor has reported altitude sickness. However, the terrain can be uneven in places, especially on the path to Wolong Ditch. Wear comfortable shoes with good grip. The lake area can be slippery after rain, and the boat docks may have wet surfaces.

The monkeys are the main safety consideration. Do not feed them, as they can become aggressive and may bite. Keep food and plastic bags out of sight. If a monkey approaches, stand still and avoid direct eye contact. Do not reach out to touch them. Parents should keep a close eye on small children. The monkeys are accustomed to people but remain wild animals.

Mosquitoes are present year-round, especially near the water. Bring insect repellent. In summer, the humidity can be high, so lightweight, breathable clothing is recommended. There are no special permit requirements for individual visitors, but organized groups may need to register at the park entrance.

## Planning a Day Trip to Longtan Lake

A day trip from Chongqing is feasible but requires an early start. Leave Chongqing by 7:00 AM to arrive at the scenic area by 10:00 AM. Spend the morning taking a boat ride on Longtan Lake (40 minutes to 1 hour) and then walk to Wangxiangtai Waterfall. Have lunch at one of the restaurants near the waterfall. In the afternoon, hike the Wolong Ditch trail and spend some time watching the monkeys near the lake shore.

If you want to include other attractions like Land Rock or the Simian Mountain summit, an overnight stay is strongly recommended. The scenic area contains more than 30 named peaks, and you could easily spend two to three days exploring.

For photographers, the best light for the Danxia cliffs is in the early morning (7:00–9:00 AM) when the sun hits the red rock at an angle. Late afternoon also works, especially in autumn when the sun is lower. Avoid midday when the contrast is too harsh.
