I was in Uganda for only 1 week. I am in my early 30s and was a bit scared of going for such an experience. It is definitely something that can be easier when you are 20 but I didn't regret it for a moment.
Leslie and the Robert (Lugacraft, The Real Uganda partner) were there for anything we might need, we have felt always safe. Leslie is the best bridge you want to take between western life and Uganda: she shared all "basic info" on day 1 over a coffee and a delicious pineapple and it all came in super handy during our week of volunteering. She prepares you to take the experience the best way.
Besides the people from the organization, the ladies we have got to work with are the most beautiful people you can imagine. Smiles, dances, singing, delicious food .. a whole other world. A beautiful world. A world they are very happy to share with you.
If you have never experience the country (or east Africa in general) there are obviously challanges: bucket showers and pit latrine toilets to mention a couple. Sometimes is tougher than you expected, but then you jump on the boda-boda (motorbikes, common way of transportation) and travel 30 mins to reach a village, and you see all those colours and those smiles. It's then when you think "this is why I am here" adn nothing else matters.
The Real Uganda is definitely the most authentic way I could imagine to embrace this experience and I am very thankful for that.
Food you can't miss: matoke (plantain based dish) and rolex (some sort of rolled dough with different filling)
