Thomson Safaris is U.S. based in Watertown, MA.  Our hiking club used them for a Mt. Kilimanjaro trek. They were fantastic. Their made all of the arrangements, for the trip, except our flights. Their staff is well trained to handle all situations and work with all individuals. They were able to answer all of our questions, take care of and see to our needs.  All individuals that work for this company are well treated. Their quality and integrity are at the highest level while being socially responsible.  Their service is the best. I highly recommend them.
