Lens Trekking and Safari Company offers safaris in Kenya and Tanzania, as well as Mount Kilimanjaro trekking trips. They suggest hiking during June-October or December-March, and thus offer most of their tours centered around these time periods. In addition, they offer tours in Tanzania ranging from 3 to 8 days. They also have 13 to 15 day safaris that go through both Tanzania and Kenya. Some specialty tours are based off the islands on the Tanzanian coastline.
