The Umbwe route is known for its caves. The first night you actually sleep at the Umbwe Cave Camp with two more caves that can be visited en route the following day. Because of the high risks involved with sleeping at Arrow Glacier camp and summiting via the Western Breach, all our Umbwe route hikes are re-routed, to join with the Machame route from night 2 on the mountain. On special request we can assist with Umbwe route hikes attempting to summit using the Western Breach / Arrow Glacier path and overnight at the Crater camp. Please note this can only be arranged through our higher quality Standard packages and a supplement rate will apply.
