Cave Stream

Cave Stream, also known as Broken River Cave, is a natural wonder nestled in the heart of New Zealand's South Island. This limestone cave system, located in the Craigieburn Valley, offers an adventurous caving experience that attracts outdoor enthusiasts from around the world. Stretching approximately 594 meters in length, the cave is a subterranean passage carved by the flowing waters of Cave Stream itself.

The journey through Cave Stream is a thrilling one, as visitors must wade and sometimes swim through chilly waters that can reach chest height. The cave's interior is a stunning display of geological formations, with stalactites and stalagmites adorning the passages. The adventure typically takes around an hour to complete, with the reward of emerging into daylight at the cave's other end.

Safety is paramount when exploring Cave Stream, as water levels can rise rapidly due to weather conditions in the surrounding catchment area. Cavers are advised to check weather forecasts and water levels before embarking and to carry appropriate gear, including a wetsuit, helmet, and waterproof light source.

Cave Stream's remote beauty is part of its allure, offering a glimpse into the raw and unspoiled underground landscapes of New Zealand. The site is managed by the Department of Conservation, which provides guidelines to ensure the safety and preservation of the cave's delicate ecosystem.
