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.

We had a really fun time in the cave. Even though it rained the night before, our guide Lachie made sure everything was safe for us. He was very knowledgeable and shared lots of interesting information about the surrounding nature and local culture. It made the whole experience even more enjoyable :D
Thank you for posting this review. Its nice to hear that your guide added value to your experience. Thank you for choosing Aventure By Nature ;-)
Exploring the cave was an extraordinary experience, over an hour of wading through water-filled passages, some of which were narrow and challenging to navigate. It was a dream come true for anyone who enjoys real adventure. Having someone experienced with us made all the difference, ensuring we felt safe and confident throughout. What truly elevated the whole experience, though, were Alan, our guide, and the thoughtful extras. There was no sense of being rushed; we had time to enjoy every moment. After the tour, we were offered warm towels to dry off and change, and we received a full set of photos and videos at no extra cost. These small but meaningful gestures made it clear that this wasn’t just a job—it was a passion project. The entire outing felt personal, well-organized, and genuinely generous. I’d absolutely recommend this to anyone seeking a rich, immersive adventure.
Hi Stalla, thank you very much for this descriptive and thoughtful review. I'm glad you enjoyed the extra touches. This is a big focus for us here at Adventure By Nature. And yes, it's more than just a job for us, we genuinely love sharing our local secrets with our guests
Jared was an excellent your guide! We had a great time going through the cave. He made sure we were safe the entire time and shared interesting knowledge about the area. We would highly recommended this tour.
Good Morning Rachel, Thank you for posting this review. Ill be sure to pass this onto your guide Jared. Kind regards
Great way to experience your first cave. Weather was great especially given the amount of water to trek though. Guide was knowledgeable and flexible. The rock garden was also great for the looking for a place to explore and even boulder.
Thank you for posting this review for others to see.
THe ride to the cave was scenic, including a stop for a snack while lunch was being picked up. the cave was quite an adventure! We'd never done anything like this and absolutely loved it! Our guides were helpful with both advice and a helping hand when necessary. We would do this again in a heartbeat! Lunch after the 1 hour plus cave trek tasted delicious and the views spectalcular
Hi Bill, thanks for the lovely review. The cave really is a bit of a treasure.
The Cave Stream and Castle Hill tour is a well-run and unique experience that offers visitors a chance to explore a hidden part of New Zealand. The tour is well-planned and takes visitors to locations that would otherwise go unseen by many tourists. In addition to the amazing natural scenery, the tour includes a delicious stop at a bakery on the way to the Cave Stream. Overall, this tour offers a fantastic opportunity for travelers to experience the beauty of New Zealand and is highly recommended.
Thanks for taking the time to leave us such a wonderful review.
Amazing trip to Castle Hill/Kura Tawhiti and Cave Stream. My guide, Robbie, was very knowledgeable and friendly and tailored the tour to suit my interests. I had a great day walking around the boulder fields, trying some bouldering, and making my way through Cave Stream's underground river and waterfalls. Highly recommend. Thanks so much for an awesome day!
It really is an amazing area to explore, glad you enjoyed the tour. Robbie is a great guide, we are lucky to have such a great team here at ABN. Thanks for the review;-)
Mike gave us what we both described as the best tour we have ever been on, and we have been on a lot of tours. Pick up was a breeze, and he was a great driver. He was very knowledgeable about the hike, and provided great guidance on how to follow the multiple paths around Castle Hill. The stop at the pie shop was perfect, and lunch was delicious, especially after the long hike. He took excellent photos of us that we would not have been able to capture otherwise. He is a great conversationalist, and taught us not just about where we were but New Zealand and its history in general. We would highly recommend this tour and this touring company, and we would book with them again.
Hi David, thanks for posting such an amazing review! We are very lucky to have such passionate and knowledgable guides such as Mike. Hope to see you again in the future. Cheers Alan
