Annapurna Sanctuary Trek FebruaryHi,
For those with experience in Nepal treks... Is it realistic to do the Annapurna Sanctuary Trek in early February? We're planning to trek during the first two weeks of February
I read that there's a risk of avalanches this time of the year and it might be difficult to go beyond Doban.

it is realistic to trek AS in There is a risk of avalanche but, I think, the risk is lower than later in the spring when there are more trekkers on the trails. The main cause of avalanche on this trek (as I understand it, open to correction...) is surface thaw and re-freeze of snow which compacts it meaning a fresh layer of snow does not bond and slides off. This thaw/freeze process is less likely to happen in February and there is less snow in Feb. This does not mean there is no risk and it's worth checking locally as you go.

2There are risks of avalanches in Annapurna sanctuary trek all round a year but some months have higher risks and some months have lower risks. Even, when I go on trek to this route I generally talk with local guest house owners to find the information. I would suggest you the same. Go on the trek but after Dovan ask in the lodges about the condition of avalanches. There will be alternative and a bit safe routes in the places of risk.
All the best!

4I trekked the route in early March without any problems and would say that in February you should be OK (Based on that I have also trekked AC in December/ January, EBC from Jiri in January/February and Langtang in February and March)
Seek advice as you go up the valley, as there are usually safer routes on the opposite side of the valley from the major avalanche shoots
Good Luck and Happy Safe Trekking

7I read all expert opinion and suggestion. it is saying from a Dovan, avalanche, in imy experience, after the Deurali it is dangerous for the avalanche. in the spring season, there is making a alternative route, next side of the river. so, can protected from the main danger area. At the time of the snow there are still slippery way because of the snow. recent condition you can ask the hotel owners and travelers.
take care and all the best.

8Paula, avalanches typically occur on slopes between 30 and 45 degrees and there are plenty of them in the Sanctuary. Slides can start on slopes from 25 to 55 degrees, but angles above 55 degree are generally too steep to collect a lot of snow, which tends to sluff off immediately after falling. Most avalanches strike during and just after a snow storm. Danger increases rapidly with snowfall of an inch or more per hour or accumulations of a foot (30 cms) or more. Storms starting with low temperature and dry snow, followed by rising temperatures, are even more likely to set up avalanche conditions This would be more likely to happen in the spring. The dry snow forms a poor bond, without strength to support the heavier snow that falls later in the storm. Rainstorms, or spring weather, with warm winds and cloudy nights can result in water percolating into the snow causing wet-snow avalanches. Rapid changes in temperature and wind increase avalanche danger.
The bottom line is that avalanches can occur at many times of the year based on the slope, amount of snow, and how it binds to other layers of snow or the ground. Evaluating the stability of a specific snow pack is highly technical and complex.
Paula, if this is the only time that you can do this trek, then go for it, but inquire locally about local conditions, and do it often! Pay attention to the amount of snow that's falling. If you have some lodge owners or staff or guides telling you that it is too dangerous to proceed because of specific conditions, you would be wise to listen to them. They probably have a lot more experience about local conditions than anyone else. I would ask about sliding potential frequently. Be prepared to turn around if there's any hint that it's unsafe.
I know this information because I've spent a great amount of time skiing and climbing in the mountains during the winter and spring. I have also lost some dear friends to avalanches, and these people were highly skilled in evaluating avalanche conditions. The bottom line is that avalanches can be unpredictable and you have to weigh your choices against the odds.
