Eisenhower Tower (II 5.5): The classic route on the mountain. This climb makes an excellent first alpine rock climbing experience. It involves a bit of scrambling, some exciting ridge climbing, a 250m headwall of rock climbing and a number of rappels on the descent. Although the climbing is never very difficult you will be challenged by the length of the day and the magnificent exposure.  9-14 hours round trip.  Group size up to 2.

Brewer’s Buttress (II 5.6): A  longer and more difficult climb than Eisenhower Tower, this route also offers excellent rock climbing throughout.  A steep hike and scramble bring us to Goat Plateau and the base of the route.  From here there are 13 pitches of rock climbing to the top!  The climbing can feel quite difficult for the grade due to the “old school grading”, the size, and the pack on your back!  This climb is also available as a 2 day ascent as there is a hut on the giant plateau half way up the mountain. 10-14 hours round trip.  Group size of 1 is recommended, although 2 guests may join if experienced at alpine rock climbing.

Super Brewers (III 5.9): This massive and excellent rock climb is the link-up of Ultra Brewers (5.9, 7 pitches) on the lower cliffs and Brewers Buttress above. It makes for 20 pitches of rock climbing and a very long rewarding day!  10-16 hours round trip.  Group size of 1 only.

Lots more including Bass Buttress (II 5.6) and Ultra Brewers (II 5.9).
