Karibu (Welcome) to our world, Tanzania, the land of Mt. Kilimanjaro, Serengeti National Park, Ngorongoro Crater, and the Islands of Zanzibar! One World Safari Tours (OWST) believes that just as the experience of tourism enriches the lives of travelers, it should also enrich the lives of the indigenous world. That is why we practice responsible tourism, tourism that allows visitors to wholly experience the adventure, beauty, and culture of Tanzania in a way that respects the local people and environment. It is with this philosophy that One World Safari Tours provides Mountain Trekking, Wildlife Safaris, and Cultural Excursions for its guests. When you experience the gifts of Tanzania through OWST, you also give a gift directly back to the Tanzanian community. OWST donates 10% of all profits to sustain local non-profit community development organizations to further the ideal of responsible tourism.
