Lukenya is owned by the Mountain Club of Kenya and entrance is free for members. Non-members have to pay for daily membership (KES400 for Kenyan citizens, KES800 for others, payable by Mpesa Paybill No. 880926, account: guest fee). No commercial groups are allowed without prior agreement from MCK. Some climbs are occasionally off-limits when eagles are nesting (in particular Eagle's Nest Face). If this is the case it is normally communicated on a notice in the sign-on book at the gate, through a climber Whatsapp group and on the relevant page on theCrag.
There are many other wild animals that call Lukenya home, including a resident leopard, snakes, hyenas. In general, these will all stay well out of your way, but be aware at night and avoid confrontations with bigger grazers like giraffes or eland. This is a wild place, so treat it with respect, pack out any rubbish, and bury human waste at least 30 cm underground (bring a spade or trowel!).
