From the famous "Kaisertalaufsteig" you follow the wide path until you reach the Veitenhof. From here you will be confronted with a fork after about 600m. Turn left and follow the partly steep path up to the Ritzau Alm (about 2 hours) continueing to Vorderkaiserfelden. Behind the Vorderkaiserfeldenhütte you take the narrow steep path uphill to the Naunspitze. Shortly in front of the peak you go right at the fork of the path in the direction of the Petersköpf and further to the Pyramidenspitze. You can the same way back to the starting point or take a different route over Hinterkaiserfelden.
