Great idea! I've done some of that, and been thrilled with the outcomes.
One of my tricks is to search companies that lead active international trips. REI. G Adventures, etc. I'm a do-it-yourself kind of traveler, but I get good ideas from what they are planning.
I've also done a lot of Google searches for hiking/backpacking in various countries or parts of the world.
And I have spent a lot of time thinking about what *I* am looking for. Day tripping or backpacking? DIY or with a group? High elevation or low? Hot or cold? Cultural experiences? Long or short? Comfortable or rugged? Good with multiple levels of ability, or not? Carry your own stuff or not?
My international bucket list includes:
- Nepal tea house trekking (I've actually done it twice, but I *highly* recommend it
- Iceland (driving the ring road and/or just taking bigger hikes)
- Pervian Andies trekking - Machu Picchu or alternatives
- European hikes (a friend of mine has gone on a bunch of self-guided hikes using this company https://www.macsadventure.com/ )
- New Zealand - I found this site helpful: https://activeadventures.com/new-zealand/about/activities/hiking/multi-day-hikes/
- Pategonia, especially Fitz Roy.
- Antarctica (not really a big hiking trip, but sure an outdoor adventure!)
There are *tons* of others.
I also subscribe to several travel sites (my favorite is https://www.smartertravel.com/ ). One day they had an article about trekking in the Everest region - and it caught my eye and my interest. So ask your friends, and keep your eyes open. The right thing will walk past 🙂
