Chimanimani was definitely an impressive getaway. Totally different from the trips I'm used to, but absolutely awesome. If you're looking for stunning waterfalls, and time out in the mountains without the crowds - this is the place to go.
If you want photograph waterfalls properly, be sure to take a little tripod along with you and if you cannot make it out first thing in the morning or late afternoon, an ND filter should help with getting a slower shutter speed. Unfortunately, I never packed either of those - lessons learnt for next time :)
