welcome to Nepal and let’s do the Hike in Nepal . I highly recommend to you that a lot of worth it to do Annapurna panorama trek ,which is takes about 8 days and it is also beautiful with popular all among the hikers .
ACT and ABC may not be open due to heavy snowing on during the end of Dec- January and which is known as winter season over here so some time trekking trail can be block by heavy snow at that moment hikers couldn’t continue to do final destination, but it depend on weather . I am happy to provide you the information on details regarding your plan so please fell free to write back to me on following details bellows;
Good luck !
