1. Altitude Sickness
Altitude Sickness is a health condition that affects trekkers at an altitude above 2,500m above sea level (NHS). The main symptoms include headaches, loss of appetite, dizziness, and difficulty sleeping. A lot of itineraries you see are designed with acclimatization in mind. In the Annapurna Circuit Trek, a few days in Manang is allocated for this purpose. A slow and gradual ascent allows the body to acclimatize properly in high altitude treks.
Drinking plenty of water with a healthy diet can help prevent altitude sickness as well. If you are prone to altitude sickness, you should take medicines like Diamox beforehand. The major thing to watch out for is that if the symptoms persist, you should descend immediately. Trekkers with pre-existing conditions such as heart or lung disease are at higher risk of falling ill. Also, alcohol consumption and smoking while high altitude trekking can contribute to altitude sickness.
The highest elevation of Annapurna circuit trek is at Thorong La Pass (5,416m) which is a considerable altitude. Even though there is a risk of altitude sickness, proper acclimatization will reduce the chance to almost zero. Most trekkers like to spend a day or two in Manang. There are short hikes in Manang which greatly help acclimatize as well.
2. Unpredictable Weather
Like any other trekking destination, the Annapurna Circuit Trek has a range of weather conditions and temperatures. As you trek from low altitude to high, the temperature changes gradually. So, it begs the question- Is Annapurna Circuit Trek Dangerous? Well, it depends on what time of the year you choose to trek and how prepared you are.
Trekking in summer and winter can be more dangerous than spring and autumn. The frequent downpours and snowfall can make the path slippery in these seasons particularly. Also there is a high risk of landslides in certain parts. In winter, snowfall and cold temperatures are the biggest enemies in your journey. So, the best time for the short Annapurna Circuit Trek is during spring (March-May) and autumn (Sept-Nov).
The temperature is most suitable for trekking and visibility of mountains is unobstructed as well. In 2014, there were a series of avalanches around the mountains of Annapurna and Dhaulagiri. After the incident, a lot of emergency shelters and better weather tracking systems were implemented. Trekkers’ en-route are now informed of weather changes and a mandatory guide system is a great help as well.Â
4. Rugged Terrain: Thorong La Pass
The Annapurna Circuit Trek has a range of terrains from subtropical valleys to barren landscapes at high altitude. At low altitude we can expect thick green forests and alpine fields. The path slowly transitions to rugged and rocky while reaching Thorong La Pass.
During the summer and winter seasons, traversing the terrain can be riskier. At high elevations, a wrong step can have deadly consequences. It is recommended to travel with a group and an experienced local guide. You can also get minor sprains and aches from hiking for a long time. You should carry bandages, ointments and medicines for such situations.
5. Remoteness & Limited Rescue
As we set out for the Annapurna Circuit Trek, we will hike through remote Tibetan villages like Manang, Yak Kharka and Thorong Phedi. Most of the trekkers opt to trek from Dharapani or Besisahar. Some tend to take vehicle ride up to Manang. After Manang, all the villages are only accessible by foot only.
There is minimal infrastructure in these villages and no major hospitals, only a few pharmacies. The medical posts in this region have limited facilities and medical personnel’s. Teahouses along the way offer basic medical aids as well.
If a serious case of altitude sickness or injury occurs, helicopter rescue can be available. For that, you have to ensure that your travel insurance covers high-altitude situations and helicopter evacuation. Before setting out on any high altitude trek, it is essential to be aware of altitude sickness symptoms and prepare accordingly.
6. Animals and Contaminated Water
The Annapurna region is home to a variety of endangered species, flora and faunas. Himalayan Tahr, Nilgai (Blue Sheep) and a few species of monkeys are native species in this region. If you are lucky you may even get to see the elusive Snow leopard. The wild animals tend to avoid humans and it is common practice to avoid feeding them. On a lot of trekking trails, stray dogs tend to follow trekkers. Most of them are quite friendly but some can be aggressive as well.
In remote trails like the Annapurna circuit mules and horses are used to transport goods. In narrow trails load-carrying mules can accidentally push or even trample you. So, as you see a herd of mules approaching you should stand on the mountainside and let them pass. Also, it is not advised to drink water from the streams or unfiltered tap. The water can be contaminated due to animal waste and be a significant health risk. You can carry water purifying tablets for stream water or simply ask for boiled water in teahouses.
7. Fitness and Clothing
For an enjoyable trip, it is customary that you condition yourself physically beforehand. A shortness of breath after a few steps can be a bad experience on such beautiful trails. The Annapurna Circuit trek takes 12-20 days depending on your itinerary and you will be hiking 5-7 hours daily. A good hiking stamina is essential to tackle such arduous journeys.
You can start building stamina by going on small hikes beforehand. Also, you will be trekking with a bag, so a moderate amount of strength training will do wonders. In addition to that, you have to prepare mentally for the trek as the journey can be hard and you may have to push yourself. It’s all a part of an experience.
Finally, let’s talk about the gear you will bring to the trek. You have to break in your hiking boots as new boots can cause serious discomfort. A proper layer of insulated clothing for cold temperatures and moisture wicking fabrics for hiking is essential. A good backpack can go a long way and a medical kit is something you should never forget. You can carry snacks to munch while looking at beautiful sceneries.
