Kirimiri is a forested hill north of Embu town that marks the transition between the settled farmland of the lower slopes and the montane forest proper that begins above 2,000 metres. The hill is accessible on foot or by vehicle from the Runyenjes road and offers good views across the Tana River valley and, on clear mornings, toward the distant ridgeline of Mount Kenya itself.
The forest on the upper slopes holds a mix of cedar, podocarpus, and olive trees typical of Kenya's highland forest zone. Black-and-white colobus monkeys are present, and the birdlife includes silvery-cheeked hornbills and a variety of sunbirds. Local guides from nearby villages know the paths well and can explain the area's significance in Embu history; asking at the Mukuuri shopping centre north of Runyenjes is the best way to arrange a walk.
