Here are the different experiences and activities that visitors can participate in during different seasons when exploring Hang En.

Unique experiences at Hang En in spring

Spring: starting in March and ending in May. During this season, the weather in Phong Nha gradually warms up but is not too hot. Hang En trekking routes are mainly under the shade of the jungle, therefore you will have the opportunity to see many types of flowers blooming, especially in April and May. Additionally, this time is also the breeding season for many different species of butterflies, so you also have the opportunity to admire the sight of butterflies flying along the trek to the Hang En Cave. If you are looking for a unique and unforgettable adventure, the Hang En spring experience is definitely worth considering!

Favorable weather conditions

Enjoying the pleasant weather of spring, Quang Binh is embraced by the cool breeze and warm golden sunshine. Trekking to Hang En during this time, customers can behold the lush green sprouts welcoming the new sunlight, traverse the glistening streams and witness the vividly revived forest after two months of hibernation. Furthermore, with such favorable weather conditions, you can effortlessly trek through the forest or even indulge in wading through the streams and rivers on the way to Hang En Cave entrance.

Witness the maximum sunbeams shining into the cave

From around December to mid-March each year, Hang En welcomes an incredibly beautiful natural phenomenon with giant rays of sunlight shining through the cave entrance from above, enveloping the entire cavern. As a result, many photography enthusiasts choose to visit Hang En during the spring season to explore, admire and capture this rare cluster of light.

Camping in one of the biggest caves

The camping area of Hang En is considered one of the most beautiful camping sites in the world, on a smooth sandy beach that is replenished after each rainy season. In front of the tents is a natural cold water swimming pool (as the water flows from underground, the water temperature can be cooler than normal) and next to it is a stream that flows into the cave from a branch of the Rao Thuong river, with sunlight making the water warmer due to the flow from the outside environment.

During sunny days in the spring, you have the opportunity to witness the magical early morning rays of sunlight shining directly into the deep tents inside the cave. With the cool air of spring, you can relax and swim in Hang En natural pool after a day of trekking in the mountains. In the evening, you can sit together and enjoy delicious food prepared by the chef right at the campsite, promising you a good night's sleep when camping at Hang En during this time. All of these elements contribute to creating the Hang En camping experience that you will not forget anytime soon!

Marking the lucky beginning

For a very long time, Hang En has been home to millions of swallows. Symbolizing the spring, the swallows signal the end of an old year, bringing luck to the new year. With the appearance of the swallows, Hang En brings a warm and peaceful feeling. Perhaps that is why Hang En is often chosen by many adventurous customers to mark the end of an old year and the beginning of a new year full of brightness.

Small group, big safety and full services

The Hang En tour has a maximum of 16 guests who camp inside the cave. Each visitor is provided with their own tent, sleeping bag and mattress with clean bedding that has been washed and dried before being used by the next group. Tables and chairs are provided for each guest to ensure cleanliness and coffee and tea are always available. Each tour includes a chef who prepares the best local dishes from the Phong Nha region. On cold days, guests can enjoy the Jungle Steambath service to relax and unwind after a long journey. Rest assured, your safety and comfort are our top priority.

Spring is also a time when many people take advantage of their vacation time to travel and relieve stress after a long period of work. As a result, popular travel destinations at the beginning of the year are often crowded with people. However, the Hang En Cave tour is scheduled so that there is only one group of guests on each tour, and only one group camping inside the cave at a time.

Unique experiences at Hang En in summer

Summer: usually starts in June and ends in August. These are warm and sunny months, with most tours having sunny days and sometimes temperatures outside reaching over 36 - 37°C. However, as two-thirds of the trekking journey are mainly on foot under the shade of the jungle, the temperature while trekking is lower and more comfortable. Another Hang En summer experience is that on the trek, you will have the opportunity to cross many cool and refreshing streams. By joining a tour in the summer, you can swim freely in the streams, rivers and jade-green lakes inside the cave, so the tour is not greatly affected by the weather.

Dry and breezy weather

The weather is dry and cool during this time of the year, with a transition between seasons, so the forest is covered in the bright yellow coat of summer. Although the temperature is high, the air is still fresh and pleasant. Two-thirds of the trekking route takes place in the forest with a lot of shady trees to rest under. After the forest section, there are streams and rivers to cross, and along the way, there are opportunities to stop and take a dip in the cool, clear water, which is a great way to beat the heat of Central Vietnam's summer.

Enjoy swimming emerald-green lake

In addition to outdoor swimming activities, when you come to Hang En, you can also enjoy swimming in the lake right in front of the campsite. The turquoise lake, naturally flowing underground from the ground, is warm in winter and cool in summer. The campsite is located near this natural lake, so you can freely swim and admire the sight of the swallows flying back to the nest every afternoon.

Enjoy the cool campsite

The campsite is cool and comfortable, with three enormous entrances located deep inside the cave. When the summer breeze blows in, it creates a refreshing and pleasant atmosphere for the customers.

The camping equipment provided is suitable, with the tent having 2 insect-proof mesh doors and 2 doors that can be used to block out cold or light. Guests can roll up one layer to let in the breeze. In addition, each tent is equipped with an electric fan to ensure customers have the most comfortable rest and prepare for their next experiences.

Unique experiences at Hang En in autumn

Autumn: from September to the end of November. Due to the slight influence of the weather from the neighboring country Laos, the weather in the Hang En area during this season may experience occasional storms that can cause several days of heavy rain in the surrounding forests. With the characteristic of a water cave with an underground river flowing through, and the valley area having many branches of rivers, to ensure the safety of visitors and prevent unpredictable Hang En autumn experience, Oxalis Adventure does not organize tours to Hang En from September to the end of November every year.

However, if you still want to embark on an adventure during the transitional period of autumn, you can consider exploring dry caves located in high positions that are not affected by floods but are still operational during the rainy season. Some recommended tours are Tu Lan Cave Experience (TL1), Tu Lan Cave Encounter (TL2), Wild Tu Lan Cave Explorer (TL3), Hang Tien Cave Discovery (HT1), and Hang Tien Cave Endeavor (HT2). Especially during this season, visitors can witness the majestic waterfall cascading down from the ceiling of Tiên Cave 1, creating a stunning and rare sight.

Unique experiences at Hang En in winter

Winter: will begin in December and end in February of the following year. In the Hang En area, January and February typically have some sunny days, but also many cold and rainy days. However, since the tours are designed to be active and frequently moving, visitors' body temperatures are maintained at a stable level that is not too cold. Additionally, they will be provided with winter sleeping bags to keep warm during the winter months. Another Hang En winter experience is that the weather in the Hang En area in January and February is considered the most beautiful time to admire the sun's rays shining deep into the heart of the cave from the large entrance of Hang En. From the campsite, guests can spend time immersing themselves in these magnificent light rays.

The weather is suitable for trekking, with temperatures ranging from 19 - 23 degrees Celsius

This is a favorable time for mountain climbing activities. With such a mild temperature, you will not feel exhausted when participating in mountain climbing activities.

Experience the cosy campsite

The time spent gathered around the pink charcoal stove at the Hang En campsite is the most anticipated time for those on winter tours. After enjoying the local chefs' culinary skills, visitors can participate in activities such as taking photos of the winter camp at night or sitting around the stove to chat and enjoy warm "la vang" tea together.

In this season, the atmosphere inside the cave and the camping areas is clear, which highlights the details of the cave. During the winter season, photography enthusiasts often go on tours to Hang En for the opportunities to capture impressive photos with optimal lighting.

Season of end-of-year holidays with family

This time of year is also the season of Christmas and other end-of-year holidays. If you want to have a memorable holiday, welcome the new year or celebrate Christmas in a one-of-a-kind location, don't miss the adventure to Hang En. Say goodbye to the old year and welcome the new year in one of the world's largest caves.

Experience special add-on services

Despite the tours taking customers to remote and challenging areas, Oxalis always provides the best services to ensure safety and create memorable experiences for their customers. Safety is the top priority during Hang En camping, and the organizers ensure that customers are equipped with the necessary gear for camping and trekking, accompanied by experienced guides throughout their journey. Gathering around the warm fire, chatting and sipping on local herbal tea to celebrate Christmas or New Year is a moment that everyone would want to experience at least once in their lifetime. Oxalis Adventure also provides Hang En camping services such as tents, sleeping bags and campfire meals to make the camping experience as comfortable and enjoyable as possible.
