As with all the reviews, it is a great place to hike, no scree, and much on grass. Yes at the entrance , they say you need armed escort ($) from one of their "rangers".... if you are going to 4th Hill. ...just say NO. Whilst in the past some young Massai may have conducted a robbery or 2 on 4 th hill (the one with a bit of tree cover), me think this is excuse for them now to get a pair to "lol, guide"you. The biggest problem on weekends is number of people and school kids and church groups.If you happen to be alone, at the start of 4 th hill is where some buffalo roam, so caution advised, more so than robbers, It is great to be at 8400 feet and the vistas of Rift Valley are great...air is clean !!!
