Travelling alone in Nepal

Yeah, no worries. Just use common sense and you'll be OK. Yer right to not pre book your treks. They are much cheaper in country. You may want to check out an outfit in Pokhara called "Three Sisters" I believe. It is a trekking business run by women for women travellers. From what I heard they were highly rated but I don't know if they are still around. Maybe another poster can help.

Have fun little sister!!

Like Bill says common sense will get you far throughout the world. I wouldn't recommend you trek by yourself or take long trips alone away from tourist centers. You don't need to book a trip, just hire a guide or find trekking partners when you get there.

Nepal is fine and there are lots of women by themselves on the trails...Three Sisters is still in operation and they are on the web if you want to find them... and since I am not a spammer please feel free to find them on google :)
Most likely you will meet a ton of people wherever you are and as such not really be alone...nepal though is a very safe place, that being said you can still get in trouble like any place on the planet. the only parts I would not want my sister out in would be Thamel late at night...

I reckon you'll be fine. I have headed off trekking in Nepal as a solo woman quite a few times (no guide or porters either) and never had any problems. In fact it's really easy to meet up with other people to trek with along the way or even before you leave Ktm if that's what you'd like. Have trekked in Annapurna, Langtang and Everest areas at different times and I reckon Annapurna (either circuit or up the Jomson side ) are the most social with the most independent trekkers and therefore best chance of hooking up with other trekkers if having company will make you feel safer.

yeah, like everyone else says, it should be fine. use common sense and do keep your gaurd up with the taxi drivers. a female friend had a taxi driver who drove her to the middle of nowhere and wouldn't let her out until she paid him 1000 rupees. i don't think things like that happen very often, but keep your wits about you. i agree with the other poster that thamel at night can be dangerous for a solo female. i always stayed with people at night and had no problems. on the trails, you should be fine too. i travelled solo over there, posted an add on this site when i got there, and met a girl who was in pokhara at the same time as me. we did the poon hill trek together and had a great time. i would have felt safe doing it alone, but much more comfortable (and fun) with somebody else! happy travels!

Head to the Busy Bee in Pokhara, there's a really cool crowd there. Ask for Rick or Moniek (Hearts and Tears Motorcycle Club) and they'll bring you on some amazing trips. You'll also meet like minded people there to hook up with. I lived in Nepal for five months last year, and had no problem hooking up with people to trek with from the Busy Bee. I'm heading back there in Dec for a month so let me know if your still there and we can do some trekking.

Thanks guys

All advice much appreciated, am so excited about this now! Will post more questions as I come up with them - such a great way to learn instead of trawling through books! :-0
