Gorilla treks take at least 3 days because it takes 9 hours to drive from Kampala. Stay at a community run ecolodge, like Buhoma Lodge, on the edge of the forest the night before your trek. Buhoma includes a good breakfast & dinner & a packed lunch They have huts with mosquito nets, a dormitory plus tent space. Occasionally the gorillas visit! You can find more upscale lodging nearby as well. Your permit for the one hour tour is $500 and with driver & lodging and it’s around $1000 total. I went in warm, muggy November, but nights were cool. Get in shape for the upward trek that may be 3+ hours. Tip your porter $15 and the tracker team $15. Wear long pants, thick socks over the pants, deet bug spray, long sleeves, hat, bandana, hiking boots, 2 liters of water, sunglasses. I brought gloves but didn’t use them. I had both a small video camera & regular camera & extra batteries. There are many places to buy wonderful souvenirs outside the lodges. Lots of birding groups stay here, too. I would suggest adding Murchison Falls to your holiday to see more wildlife and enjoy the beauty. Remember to breathe when you first see the gorillas! .
