On top of the world | At any age.
If you are thinking that you would like a new challenge in your travels, here is a suggestion.
Perhaps not something that you would normally think about, but seriously consider going trekking in Nepal. You will not regret it ............ well perhaps climbing up and down innumerable steps will have you thinking, but the views, the villages along the way, the "tea" houses, the people and the challenge more than compensate. The secret is not to take on more than you are able to cope with, and there are plenty of "cultural" focused trips instead of aiming to get to "Base Camp". Along the way you'll meet a variety of travellers, for some, it's all about the "destination", and for others it's all about the "journey", but for everyone its an experience to be remembered.
The most common phrase used on our recent trip was "Look up, look up". After watching where you are placing your feet along the trail, you forget the amazing sights that are all around and above you! And once you do look up, you have to take a minute or two just to take in the fantastic view.
