To successfully hike the mountains, I have some tips for you [in no particular order] especially for amateur hikers like me. Tips collected from personal experience and collected from other experienced hikers. Rain and sleek or dry, these should come in handy.
// Wicking clothing.
It is hot and humid in the mountains. Having moisture-wicking clothing was more comfortable but on the day I did not wear that fabric, I was drenched. Not a deal killer for me but if you are sensitive to sweating, definitely look into moisture-wicking clothing - you can use it for your Safari as well.
Greystoke Mahale provides a poncho but for a smaller person like me, I found myself tripping on the way up and down the mountain. Having my own rain jacket would have been more comfortable. I do have to say that the poncho did cover my camera packed back-pack when it was raining hard so if you do take a raincoat, see if it will cover you and your back-pack. Or stick with the poncho.
When Sally said she was getting this, I was not 100% convinced I should get the gaiters but I am glad I did. It kept my socks very dry. Which leads me to then next must item ...
// Waterproof hiking shoes - if you can.
I had Columbia Peakfreak hiking shoes and I could not have been more comfortable. They gave me traction, kept my feet dry and kept me blister free. I wore mine with Smart Wool socks. Happy hiker here.
// Camera solution.
A fellow trekker could not use his lens because of moisture. Make sure you have a water proof protection / backpack for your camera on the climb - he had it around his neck, and making sure you have a good seal for your lens + camera. Have a back-up as well if you can.
Another personal note - I lost my lens cap on the mountains and some chimp is playing with that. In the fluster of climbing up fast, setting up the camera quickly, etc., I dropped my lens cap and realized too late. Note to self - secure your lens cap with a cord.
// Camera Tip.
Learn your camera. Have it set for the quick shooting in low light and definitely know your settings if you are planning on using manual. The camp manager and guides like Butati at the camp were helpful with suggestions. It is dark, humid, and the chimps can be 5 ft. away to 50 ft. so what type of lens to carry is the million dollar question. I had my 70-300 mm lens and used my iPhone for the close-ups.
// Other trekking notes.
- Energy bars and sweet bananas were provided by Greystoke Mahale - they really helped with giving the group a nice boost on the trek.
- Bring extra cash. There were other people besides our guides who took care of us like the trekkers who start early to find the chimps and Tanzanian government rangers.
- Self care items like for blisters, scratches from the forest, balm for the hard trek.
