Even just hiking and camping on the slopes or visiting the ash cone in the much lower crater are walking safaris that I can warmly recommend. You will be amazed by the amount of wildlife you can find on this mountain, the vegetation is stunning all the way, and Meru simply isn't as overrun as Kilimanjaro is. (For people who are doing walking safaris on the lower slopes or in other areas of Arusha National Park there are several campgrounds. And for those wanting to do a safari in style there are a couple of very comfortable lodges just outside Arusha National Park.)
