We've put together photos and descriptions to provide examples of the terrain you'll encounter in the Caroline Hut and Ball Pass area, to help you prepare for your mountain adventure.
What to Expect on the Approach to Ball Ridge
The route begins with a rugged 4WD journey up the lower Tasman Valley before setting out on foot. Regardless of which route is taken to get onto Ball Ridge, you'll be crossing challenging terrain affected by glacial recession and large weather events.
Due to significant glacial recession and moraine wall washouts, the landscape is constantly shifting, requiring careful route-finding and caution when crossing loose or eroded ground. Alpine scrub thickets provide their own challenges, with patches of Dracophyllum and speargrass making sections slow and scratchy.
The terrain steepens into steep tussock hillsides and rough scree slopes, where sure-footedness and strong legs are essential. As you climb higher, expect to encounter large boulder fields, requiring balance and good movement over uneven surfaces. In places, you may need to use your hands to scramble over short rocky steps. The snow tussock provides its own challenges as it becomes very slippery when wet or covered in snow.
Depending on conditions, crampons and ice axe may be required to cross frozen snowfields and harder alpine surfaces. Your IFMGA / NZMGA qualified guides will teach you these essential alpine skills.
Ball Ridge to Ball Pass and Kaitiaki Peak
The route toward Ball Pass continues into more technical, glaciated terrain. Expect steep scree slopes, snow slopes, and narrow rocky ridge-lines, where sure-footedness is essential.
The ascent involves negotiating loose rock, small bluffs, and exposed sections where confident movement over alpine terrain is important. You’ll climb through a world shaped by ice and weather, with towering peaks, hanging glaciers, and sweeping views across the Tasman Glacier below.
Crampons and ice axe are required to cross permanent snowfields and glaciated sections. Your guides will help you to master the correct technique, to ensure you can move safely with mountaineering equipment.
Long, Steep Descents on Rough Terrain
Going down through steep scree, large boulder fields, and tussock slopes can be physically demanding on knees and ankles. Careful foot placement and concentration are needed throughout to manage the rough, uneven terrain. Trekking poles can help with this.
