Hi,
Sorry for the late reply. As Nepal_Trek has mentioned that it could be difficult to Thorong Pass, I sort of give up hope that noone would be interested in joining me. Well, Annapura full-circuit will take 21 days or more to cover, but half circuit will take 17 days. The approximate trekking per day could be 5-6 hours. Following is the my trekking plan, which I hope is useful to you.
Day 01: Drive from Kathmandu to Beshishahar.
Day 02: Trek from Beshishahar to Bahundanda (1305m.) and it takes about 6 hours.
Day 03: Trek from Bahundanda to Chamje (1410m.) which takes about 6 hours.
Day 04: Trek from Chamje (1410m. ) to Dharapani (1960m.) and it takes about 6 and half hours.
Day 05: Trek from Dharapani to Chame (2675m.) which takes about 6 and half hours.
Day 06: Trek from Chame to Pisang (3100m.) which takes about 5 hours.
Day 07: Trek from Pisang to Manang (3440m.) and it takes about 5 and half hours.
Day 08: Rest day at Manang and hang in and around town.
Day 09: Trek from Manang to Yak Kharka (4350m.) and it takes about 3 and half hours.
Day 10: Trek from Yak Kharka to Thorong Phedi (4420m.) which takes about 3 and half hours.
Day 11: Trek from Thorong Phedi to Muktinath (3850m.) via Thorong La (5416m.) Pass and it takes about 7 hours.
Day 12: Trek from Muktinath to Kagbeni (2895 m.) and it takes about 3 and half hours.
Day 13: Trek from Kagbeni to Jomsom (2713m.) which takes about 3 and half hours.
Day 14: Fly from Jomsom to Pokhara which takes about 20 minutes.
Day 15: Drive from Pokhara to Kathmandu by tourist mini bus that takes about 7 hours.
I have done some research on it and see many remcommendation that going to Kathmandu to get a porter is as good as getting a confirm tour guide over the website. It could be a challenge to do so, but I believe it should not be a problem. I have been there once and most of the Nepalese are very honest and friendly. I have trust on them.
Regards
Te
