Excellent trip. Warm welcome and well organised throughout. The boat ride across the lake was a lovely experience in itself; the cave visit was supplemented well by helpful and informative presentations.

There are 3 parts to the Te Anau glow worm caves experience. One part is the boat ride over and back where you see some amazing scenery in all directions. Another part is the information session where you learn about both the cave system and the glow worms. And the third is the walk through the caves before boarding a punt that quietly drifts along while pinpricks of light can be seen on both sides and overhead, and eels and fish can be seen in some of the still ponds. All of that was absolutely fascinating, but for me it was the rushing and pounding of the river and its waterfalls that showed how the caves were made tens of thousands of years ago. The boat crew and tour guides were terrific. If I could give the trip 6 years I would.

While rather a journey to get to Doubtful Sound, the scenery is well worth it. We had nice sunny weather which made for beautiful scenery and lots of wildlife. My favorite part was when they shut off the engines and 70+ strangers from all over the world put away their cameras/cellphones and just stood in silence for several minutes. It was really special to hear the bird calls and the gentle lapping of waves while surrounded by all that beauty. Everyone with the tour were great, friendly and full of information.

Back in winter I undertook a coach and cruise tour to Milford Sound with RealNZ from Queenstown. It was a 13 hour mammoth effort that i'll be honest, I wasn't really looking forward to (for the travel time alone). But wow, how wrong could I have been. Aside from the obvious benefits and amazement that a tour to this spectacularly scenic location brings, hands down the single best thing about this tour was the obvious effort and expertise our bus driver guide, Pete, put in and was able to offer along the way. We started bright and early in the morning, but despite the early hour Pete was chock-full of engaging tales and interesting insights into everything from the local geography and geology, to the history of the region's founding and everything in between. The day seemed to whiz by with ease, and was capped off by a beautiful cruise through Milford Sound to end the afternoon in absolute glory. My solitary critique was that we were a little rushed at the Milford ferry terminal, but were loaded economically and efficiently onto the boat ready to depart just in time! An absolutely wondrous day, and thoroughly pleased I chose to opt for a tour rather than a self-drive option.

Many of our friends and family who have visited the TeAnau area said that seeing the glow worms was a Must-Do. We are glad we took this excursion as the worms certainly are unique; however, the number of worms we saw on our visit (late November) was not as expected. A recent event that flooded the caves is possibly the reason. Thomas was our guide and was very good and knowledgeable; however, being at the end of a 12-person group, there were times he was making a point and we were too far back to see or hear. James led the short video presentation at the center at the end of the tour. He was excellent! The film showed more about the worms than we knew and was very informative.

Our travel agent booked this tour as part of our overall package and we probably didn’t pay sufficient attention. So Doubtful Sound is very scenic and the staff at RealNZ are very nice and helpful however, for us it was a bit too much travelling. If Queenstown is your first stop in New Zealand, the trip is probably worth it, however we had driven from the top of North Island to Queenstown and seen lots of great scenery on the way. We were picked up from our hotel at 0720 and the coach set off around 0745 to do a few more pickups before setting off around 0800. It’s a two hour drive to the lake with an extensive commentary and then 50 minutes across the lake for a 40 minute coach transfer across the southern alps to the cruise itself which then takes around 2.5 hours. We saw some seals and possibly some penguins. It’s worth noting that if you’re a nervous passenger the transfer is on a gravel road with a 1:6 gradient in part. You then travel back, arriving in Queenstown around 8pm. There was a good packed lunch as part of the package and the boat has a good selection of drinks and snacks, taking credit cards. In retrospect, we probably would have opted for the Milford sound tour as it’s more convenient.

A Wonderful trip, a definite must do, those little worms are spectacular and the cave system is impressive. Thank you to ALL the crew, you are all doing an amazing Job. Our guide was Jess and she is terrific. Kind regards Michelle and Steve from 🇦🇺

Great experience- went with 2 teenagers they loved it - lots to see, great tour guide and loved that the groups into the cave weren't too large. It was a little cold on the afternoon we went but the boat was warm inside. Recommend if travelling to Milford Sound otherwise a little far out from Queenstown.

This is an amazing trip. If you are claustrophobic, or scared of bridges then its not for you. A catanaran takes you across the lake to the Glowworm caves. You walk through caves (you have to bend down in some spots to walk through), and over powerful waterfalls (which could be unnerving). Eventually you get in a boat, and in complete darkness, you see the glow worms, while the guide directs the boat. Fabulous experience overall

A cool and unique experience. Staff were very friendly and had lots of interesting info on the caves and the glow worms. Be mindful that the entrance to the cave requires you to stoop quite low to enter. Could be an issue for someone with mobility impairments. Also, I would recommend you wear long trousers. I wore shorts and got eaten alive by the sand flies! Overall, a fun trip, fully recommended.

My whole day cruise through Doubtful Sound was simply breathtaking. Thanks to the awesome weather, the journey offered stunning road views, though due to the journey's length, there were only a few photo stops along the way. Doubtful Sound itself was mesmerizing, a true natural wonder. Our tour guides, especially Ram, were both funny and knowledgeable, adding to the experience. I did feel tired at the end of the day, but I also felt accomplished. A day well spent!

The 25 minute speedboat trip to the caves was fast and informative, the splitting of the groups into 12 people done quickly and then straight onto a boat for our group. We were a little disappointed in the lack of glow worms but that is due to a recent flood of the caves. The tour guide was friendly, kind and helpful. Overall we thought it was a lovely trip that we were happy with and our 12 year old loved.

A lovely experience a chance to see a unique part of nature in a wonderful place. The ride on the boat is smooth and gives you a great view of the local mountains, the caves are interesting and the worm viewing experience quite different. Worth going to.

Magical moments under the glow worms. Just as impressive was the underground tunnel system with rushing waters beneath us and towering rock cathedrals above. Really, a once-in-a-lifetime experience.

It was a nice way to spend the evening, and walking around the caves was pretty cool. The tour guides were really helpful Visitors are not allowed to take photos or videos inside the caves (totally understandable), but the glowworms aren’t as bright as some of the photos might have you believe. They appear as tint little dots, and the number you see will vary.
