Caving Adventure with Optional Castle Hill Rocks Tour

This adventure lets you experience one of New Zealand’s most accessible underground rivers as well as the dramatic limestone landscape of Castle Hill—available in several flexible tour options. At Cave Stream, your guide leads you through a 594-metre limestone passage shaped by crystal-clear water, small waterfalls, and winding chambers, finishing with a fun 5-metre ladder climb. It’s a memorable, family-friendly caving experience that requires no previous skills. Options that include Castle Hill/Kura Tāwhiti offer the chance to wander an incredible labyrinth of giant limestone boulders, an area rich in cultural history and famous for climbing and film locations. Try some easy bouldering or simply enjoy the scenery. (Lunch is provided only in the options that include it.) Whether you choose caving only, add Castle Hill, or join the full day with transport, you’ll experience one of the South Island’s most unique alpine environments.
