3) Kilimanjaro Climb:
Now, this is not going to be a trip for every over 40 out there. You are going to need to be reasonably fit. However, climbing Kilimanjaro, even just a small way up, is not actually going to be all that difficult. There are a number of tours heading up the mountain each and every day. They will, of course, work to your pace. Some of the routes up the mountain are pretty easy and you should be able to get some pretty decent photographs whilst at the top.
