Day trip to Rangitoto

We caught the 9.15 ferry from downtown Auckland, armed with sunscreen and sunhats, drinks and lunch (there are no shops on the island, so you need to come prepared), sturdy walking shoes (or, in my case, sandals) and cameras. And the camera came out early as the huge cruise ship Celebrity Solstice was docked at Princess Wharf, the clouds were very pretty and the sea an incredible blue.



The direct ferry ride only takes about 25 minutes so Rangitoto is the perfect distance from the city for a family day out and the perfect destination for those interested in the geology, those wanting to explore the many hiking tracks or check out the native wildlife, or those who simply want to enjoy a day away from the hustle and bustle of city life.


Rangitoto Island is the youngest and largest of the Auckland region’s 50-odd volcanoes, having formed by eruption about 600 years ago. Rest assured, it is now dormant (!), but it still provides a fascinating glimpse into the geology of a volcano. For those interested in such things, the hiking tracks give up close and personal glimpses of old lava flows, large heaps of scoria and, at the top, the summit crater.


The island became a Public Domain way back in 1890, with the first wharf and track to the summit being built in 1897. Prisoners from Auckland’s Mt Eden prison were used to build some of the roads in the 1920s and 30s and, nowadays, those roads and the well-maintained series of walking tracks mean that visitors can choose to tackle the summit path for awesome views of Auckland city and the Hauraki Gulf, or simply spend the whole day exploring this fascinating island.


The trek to the summit takes about an hour – it is family friendly (we saw one family wheeling and carrying a baby buggy all the way to the top – just a little mad!) but, be warned, the final part of the ascent is quite steep, though easy enough to negotiate. Those who are less mobile can pay to join the Rangitoto Volcanic Explorer tour, which takes you round the island seated on a 4WD road-train, of open-air carriages pulled behind tractors, though you still have to walk up a long series of 300 wooden boardwalk steps to get to the summit.


Of course, we joined the walkers heading for the summit – you’ve gotta do it at least once! The walk takes you through lava fields and native forest and, as you climb, there are frequent opportunities to stop for photographs of the ever-more-awesome views – the perfect excuse to catch your breath and take a drink. The 360-degree views from the summit are spectacular, ranging from the rugged horizons of the Waitakere Ranges in the west across the central city and the beautiful islands of the Hauraki Gulf to the Hunua Ranges in the south. 


We came back down the alternative boardwalk route, then made our way along the unsealed road to the Rangitoto Wharf. It was a long walk but we were entertained by tuis warbling, by more fantails than I’ve ever seen in one day before fluttering back and forth across our path, and by wrens flitting in and out of the bushes. On the summit, I also saw my very first saddleback – sadly, it was too quick for a photo.

Rangitoto is home to the world’s largest pohutukawa forest, as well as trees that are a strange hybrid of pohutukawa and northern rata. The lava outcrops seem inhospitable but, over time, they are gradually colonised by lichen and ferns, followed by shrubs and bushes, then eventually the trees. The island is home to more than 200 species of native plant, including 40 different types of fern and several species of orchid.


Back down at the wharf, we tucked hungrily into our well-earned lunch and rested a while, before taking the track west along the coastline. These days no one lives permanently on the island but, in the early 20th century, a small community of people lived in the baches (a New Zealand word for a simple holiday house) that line parts of the shoreline. In the 1970s and 80s, a large number of the old baches were demolished but, these days, those that remain are registered as Historic Areas with the New Zealand Historic Conservation Trust, and many are still used as holiday homes by the descendants of the original owners.


The Trust has done a great job of researching the families who have lived in the bach communities over the years, collecting over 50 oral histories and more than 300 photographs. At the empty sites of those baches that were knocked down there are signboards telling the histories of the places and their people. They provide wonderful glimpses of Kiwi history.

The bach nearest Rangitoto Wharf, Bach 38, has been restored to its original condition, complete with all the fixtures and fittings you would have found in a bach dating from the '30s or '40s. The bach was built in 1927 for Walter Pooley, the first caretaker on the island and then-owner of the shop and tearooms (since closed).


We relaxed some more on the benches of the information kiosk near the wharf, before joining the hordes of tourists boarding the ferry for the breezy voyage back in to the city. We were weary but content, having enjoyed the strenuous exercise, the refreshing sea air, and the entertaining birdlife. It was a most excellent day out!



Acknowledgement: Much of the historical information in this blog came from a brochure provided by the Rangitoto IslandHistoric Conservation Trust, whose objective is to ‘find ways to retain the bach communities much as they exist now and make them available for public use’. Together with the Department of Conservation, they are working to restore, preserve and maintain the baches, and have compiled an impressive archive of material about the Rangitoto community. They are making a noteworthy and commendable contribution to maintaining Auckland’s heritage.

Bolivia day 4: superlative!!!

Our wake-up knock was at 6.45 but I was already up and showered. We had breakfast and then headed off into the wild blue yonder. And it was wild – the landscape, the creatures, the ride. And it was blue – the sky was an unbelievable shade of blue, so clean and clear.

Al, the tour guide, rode in our 4x4 all day but that just meant listening to his mix tape several times over – he wasn’t exactly a mine of information and saved what he had to say till we stopped, so he didn’t have to repeat himself. But the scenery spoke for itself and I struggle to find the right words to describe how amazing, outstanding, awesome it was.

After heading south from the salt flats and climbing up over ancient lava flows, our first stop was at the end of an old lahar, where the lava had petrified into weird and wonderful formations and where there was a great view of the active Ollague volcano – just steaming fumeroles near its summit, no explosions!

This was just the beginning of a day of dramatic scenery in what must once have been an incredibly active volcanic area. We drove past some high snow-capped mountains and others stained with the white, yellow and rust colours of the mineral emanations of extinct volcanoes. The photos of these places look like they’ve been photoshopped but, believe me, they are real.


Next we came to Lake Cañapa, the first of the nine breathtaking lagoons that dot the Andean Altiplano and here we saw our first of the three species of flamingos (the Andean, Chilean and James) this area is famous for. One interesting fact Al told us was that the flamingos have the ability to control their heartbeat, to allow themselves to sleep in the water to try to avoid their enemies, the fox and the puma. However, when it’s cold (and it gets down to the minus twenties and thirties in winter here) the water freezes and the flamingos become trapped.


So elegant!

A small herd of vicuña






























This beautiful lake-side setting made the perfect place for our lunch stop – we carried food with us and the drivers prepared our lunches each day. 

And cameras clicked constantly, recording for posterity the scenery and the wildlife. 

A small group of vicuña, the llama’s little cousin, came down to drink from the lake and, as we were leaving, a culpeo ran across in front of our vehicles. 

Also known as the Andean fox, it is actually a South American species of wild dog. 

It lingered, familiar enough with tourist vehicles to expect some food and it wasn’t disappointed.

Its normal diet consists of rodents, rabbits, birds and lizards, but it also enjoyed the chicken bones left over from our lunch.


The next lagoon was officially named Hedionda but has long been known as ‘Stinking Lake’ due to its high sulphur content. According to Wikipedia, the lagoon also has mineral deposits of thenardite and ulexite, gypsum, lithium, boron and potassium, amongst others. The large flocks of flamingos didn’t mind the minerals, or the smell. More photos!

As we drove on, we began to cross the Siloli Desert, the highest in the world at 4500 metres above sea level. It’s not large – only about 100km2 – but it contains some strange formations of volcanic ignimbrite or petrified lava, eroded over the aeons by the violent power of the wind. The stone tree is the most well known, but the surrounding rocks were equally stunning. And, as the wind was fierce and the sand was stinging any exposed skin, I could certainly understand how the rocks had been ground down.



At the edge of the desert we saw more wildlife, the northern vizcacha. This member of the chinchilla family looks like a cross between a rabbit and a squirrel and is native to the Peruvian Andes. It lives in large colonies, separated into individual family units, and eats a wide range of plant matter, settling for almost anything it can find growing in the harsh, rocky environment. It also eats hunks of bread, which was all we had to entice the bunnies down from their rocks. They were most obliging and, once again, the camera shutters clicked madly.

More driving followed, which sounds tedious, but every turn presented another remarkable panorama and our last stop of the day was the most remarkable of all. At 4300 metres above sea level and with an area of 60km2, Laguna Colorada, or Red Lagoon, literally is red, due both to volcanic sediment and the microscopic algae that thrive in its waters. The lagoon is shallow, only 30 to 50cm deep, and is surrounded by the white mineral borax, so is considered the perfect habitat for flamingos. And the plumage of these flamingos is more red than normal because of the algae in the lagoon. You guessed it – more photos!
We had entered the Reserva Nacional de Fauna Andina Eduardo Avaroa at the Red Lagoon, and spent the night very close to the lake, in a very basic hostel where the six of us from each vehicle slept in the same room. Dinner wasn’t ready till 9pm and it was lights out again at 10. Luckily, we were given hot water bottles and sleeping bags, as well as blankets, as it was very cold. Most of us slept in our clothes! The next morning, Richard told me I had been laughing in my sleep – I don’t remember why but maybe my laughter was a reflection of what a superlative day it had been.
