The Glowworm Caves

New Zealand is home to this natural wonder. The glowworms are widespread in New Zealand generally in cave systems. The most popular of the cave systems to view glowworms are at Waitomo, Te Anau and Waipu.

A short introduction on the glowworms

The New Zealand variety of glow worm is actually the larva of an insect which looks like a mosquito. The scientific name is Arachnocampa luminosa. The larva produces a blue green bioluminescence. The Maori name is “Titiwai “meaning projected over water. They live in dark, cool , damp and humid environments like caves, sheltered banks and native bushes.

This is not to be confused with fireflies which also are bioluminescent but belong to the beetle species.

The insect eggs are deposited on cave walls. On hatching, the larvae immediately begin to glow. They grow from the initial size around 4 mm upto 40 mm. over several months. They move around the cave wall and finally attach themselves to a site and start producing a silk nest. The larva produces long silk threads which have sticky droplets on them to capture prey.

The bioluminescence is a result of an enzyme luciferase acting on a molecule called luciferin. Though the enzyme has similarities with that found in fireflies and other bio luminescent systems, the composition of luciferin is totally different in this species. The purpose of this glow has been attributed to attracting prey and also potential mates.

Our Trip

We decided to do the glow worm tour at Te Anau. Real Jouneys is the tour company which organizes these tours from Te Anau.

The glow worm caves lie in the mountains across the Lake Te Anau .The caves are around 12000 years old and are still being carved out by the force of the water that flows through them. The result is a twisted network of limestone passages, whirlpools and an underground waterfall.

Tourists have to take a catamaran to the other side of the lake. These caves are situated close to the water level and the trips are called off if there is flooding in the caves. The trip was cancelled on the previous day due to heavy rain and flooding of the caves.

We were lucky to get a rain free day to do the trip. The catamaran ride lasted about 40 minutes.

Once we reached the other side, we were guided by helpers to get across the slippery rocks on the edge of the lake. The whole area has a very marshy , damp , slippery appearance with dense vegetation .Then we were guided to the Cavern House. The Cavern house has tourist facilities like a small cafe , toilets etc and has a small hall where the guides explained about the bioluminescence and the larvae . There are educational exhibits here too…

Photography is strictly prohibited in these caves.

After the educational session, we were divided into small groups with a guide for each group. We followed the guide along some narrow passages among caves. At many places, limestone formations are seen inside the caves. One has to bend and turn and manouvre oneself to prevent injuries from jutting rock formations. As we went further inside, it got darker. The guide had a headlight on her forehead. At places, there are steps made manually too. At places there are small lights too.

As we walked along the caves, there were silk threads visible at places. But the larvae could not be seen. Finally we reached a small area with flowing water and we boarded a very shallow boat. The boat is so shallow that you cannot sit upright. This is also to prevent injuries to the head as the boat goes through the narrow channels.

Once the boat was on its way, we started seeing the beautiful blue green light all along the walls of the caves. At places, it was very bright and at places it was dull. I assume it depends on the density of larvae at that site. It was indeed a great experience. It looks like a sky lit up with stars!!

After this wonderful experience we were treated to some hot coffee and took the cruise back to downtown Te Anau.

Our trip to Milford Sound was scheduled for the next day . See you next week at Milford Sound….another beautiful location.

Till then, good bye

Te Anau

After pulse raising Queenstown, our next destination , Te Anau was a total contrast. A quiet, peaceful ,small town. We took a bus to Te Anau and were the only passengers on the bus. The driver directly dropped us off at our hotel at Te Anau.

The hotel had a beautiful ambience and was very cosy and homely.

First let me tell you about this cute little town….Te Anau.

Te Anau in Maori language means Place of the swirling waters

Nestled on the edges of the picturesque Lake Te Anau is this pristine , quiet town of Te Anau. Lake Te Anau is the largest lake in the South Island and second largest in New Zealand. The Mt Luxmore and Murchison mountains form an awe inspiring backdrop to this beautiful lake.

Te Anau is the gateway to Fjorland National Park. Though Fjorland can be reached from Queenstown also , Te Anau is closer and the drive less tiresome. Te Anau came into the lime light only after the opening up of the Homer tunnel on the 120 km alpine road to Milford Sound . It has since become a hub for those visiting Fjorland. It is also the hub for those doing tramping at the Kepler and Routeburn tracks which is a loop adventure activity along the tussock covered alpine vistas.

We decided to do a day trip to Milford Sound( Fjorland) from Te Anau. Since we were at Te Anau during the fall season, the fall colours added to the beauty of this place. Some pictures…

The Takahe…

It is a variety of swamp hen indigenous to New Zealand. It was extensively hunted by Maori and was considered extinct. But was rediscovered in the late 1900s in the Murchison mountains close to Te Anau. It is now considered a threatened species.

There are many activities one can undertake at and from Te Anau. Some such activities:

Day tour of Milford Sound:

A two hour ride on Milford highway passing the Homer Tunnel and a cruise on the famous Milford Sound…the detail episode on this trip coming up soon!!

Fjorland from air:

A helicopter or float plane ride over the fjords and sounds of Fjorland National Park.

The Glow worm Caves

Across the Lake Te Anau lies a glow worm grotto which can be explored. We did this and I will be doing an episode on these caves soon

The Great Walks

The Kepler, Milford and Routeburn tracks offer a magnificent way to explore the unique eco system of Fjorland

Apart from these activities, Te Anau is a nice destination for a quiet break in the midst of a hectic sightseeing schedule too.

Digressing a little from Te Anau, I have mentioned a lot about the scenic beauty of New Zealand. It is time I told you about the beauty of it’s people….

I had mentioned that Kiwis are great hosts and that tourists are treated with warmth and affection in New Zealand…some instances

Athithi Devo Bhava!!!

I must tell you about a very interesting anecdote from Te Anau. Apart from the sheer surprise, it really points out the sincerity with which the Kiwis treat their tourists. We were strolling around Te Anau town one afternoon as our connecting bus was scheduled only in the evening. Suddenly I saw a bus parked on the street with my name written on it. I just could not believe my eyes!!. There was a contact number asking me to contact the person to schedule an early departure.

Imagine seeing your name on a bus in the middle of a small town somewhere in New Zealand!!!….I had to pinch myself to be sure I was not dreaming!!

When I called him, the driver said that he is free and since we are the only passengers in the bus, he will take us as per our convenience. Mind you, this is a government intercity bus booked online from India! To fulfill their commitment to the tourist, they were not only running the bus but adjusting to our requirements. This is really Athithi Devo Bhava(our guests are like God)….a famous Indian proverb! There were at least two instances where we were the only passengers in a luxury bus and the driver dropping us directly at our hotel.

Athithi Devo Bhava….Kiwi style!!!

The Intercity bus

When this driver dropped us at Queenstown, he called up a cab and put us in the cab to our hotel. All this without any request from our side.

At another place called Rotorua, which I will cover later, the receptionist at the hotel waved down a bus and helped us carry our luggage to the bus. Mind you, its a regular local bus. And the driver of this bus digressed from his regular route and took the adjacent street so that he could drop us at the correct bus station….with no complaints from our co passengers!

Many a time, local passengers ahead of us in queue would let us board a bus first .

When we expressed our surprise and appreciation of this kind of hospitality,the reply was

“You are our guests and it is our responsibility to get you safe to your destination”

This motto is followed by everyone…it is almost like a rule…that tourists should be assisted at all places.

I really wonder how this approach has been ingrained in all the people there. Definitely something worth emulating!

Well, this episode has shown you the beauty of the land and its people!

Next I will meet you at the Te Anau Glow worm grotto….with those beauties that spread light even in darkness….
