Led by the Australian geologist we climbed the volcano. With his jeep we drove as far as possible on the slope of the mountain where we then walked through the jungle. There was no hiking trail, but the local guide knew exactly where to go.
In these latitudes the tree line is far higher than in our temperate zones, finally we started the last part of the way, which has been
only loose lava rubble which slipped under our feet. We finally reached the edge of the crater in altitude of 2.892 meters (9,485 ft). The geologist wanted some rock samples.

Whakaari / White Island is an active volcano which lies around 48km offshore from the New Zealand's Bay of Plenty.
The volcano erupted violently, and tragically in December 2019 while 47 people were on the island. There were 22 fatalities, and the 25 survivors were seriously and critically injured.
Increased activity had been recorded from February 2021, and a month after this image was captured there was an ash explosion.
Even viewed here from the coast 48km away, it's clear that the volcano was still quite active in July 2021, and a maritime exclusion zone remained in place around the island.
How the Galapagos mockingbird got its name…
“Mockingbirds don’t do one thing but make music for us to enjoy. They don’t eat up people’s gardens, don’t nest in corncribs, they don’t do one thing but sing their hearts out for us. That’s why it’s a sin to kill a mockingbird.” Harper Lee, To Kill a Mockingbird
Metaphors aside, this quote from Harper Lee’s famous book states that “it’s a sin to kill a mockingbird”. Fortunately, a hundred years before the book had even been written, a young Charles Darwin didn’t share this view, for if he had he may never have published his famous book. During the voyage of HMS Beagle, Darwin shot and collected hundreds of specimens including a good number of mockingbirds, or mocking-thrushes as he called them. It was these specimens more than any other that led him to develop his theory of evolution by natural selection.
Darwin noted that mockingbirds differed slightly between islands in their size, beak shape and markings but still closely resembled the mockingbirds that he had collected from mainland South America. This, along with other observations such as the differing shell shapes of giant tortoises, made him question the long-held belief that all species had been created in their current form, and it was these thoughts that led him to formulate his revolutionary theory.
Four species of mockingbird can be found in Galapagos, none of which occur anywhere else on Earth. Genetic analysis has shown that all have descended from a common ancestor, likely to be the original Galapagos settler, who’s closest living relatives are the mockingbirds found in North America.
The Galapagos mockingbird (Mimus parvulus) is by far the most common of the four species within the Archipelago and can be readily spotted in the forests and shrublands of many of the larger islands. The other three species are the Espanola (M.macdonaldi), San Cristobal (M.melanotis) and Floreana mockingbird’s (M.trifasciatus), named after the islands from which they originate. Sadly, all four species are listed on the IUCN Red List of Threatened Species, the most threatened being the critically endangered Floreana mockingbird.
Once common on Floreana, the mockingbird population is now restricted to two small satellite islands and may number less than 200 individuals. The principal threats to all of the mockingbird species are predation from introduced predators (namely rats and cats) and loss of their favoured nesting and food source, the prickly pear cactus (Opuntia spp.). Fortunately, a long-term project which GCT has been involved with is focusing on restoring Floreana to a more natural state, the hope being to eventually reintroduce the Floreana mockingbird back onto its native island.
Originally named mock-birds (1640’s), mockingbirds are so named due to an interesting behaviour carried out by some species whereby they mimic the calls of insects, amphibians and other bird species. None of Galapagos’ mockingbirds perform their namesake behaviour, but they do have a series of calls which they will use under different conditions.
Amazingly, marine iguanas appear to have learnt to recognise the alarm calls of mockingbirds and have been shown to act upon them. Sounded when a predator is spotted, iguanas will often go into a heightened state of alert when an alarm call is raised. This makes sense given that the two share many of the same predators, such as the Galapagos hawk (Buteo galapagoensis), but it actually has a uniqueness to it. Whilst there are many examples in the natural world of one species reacting to the calls of another, such as meerkats reacting to fork-tailed drongo alarm calls in the Kalahari, this is the first time that it has been recorded in a non-vocalising species such as the marine iguana (an article on this behaviour can be found here). Another little Galapagos oddity!
There seems to be a strange irony in the fact that the bird that played an integral part in Darwin’s theory of evolution has evolved to no longer show the behaviour that gave it its name. What is certain is that these bold and charming birds are always a pleasure to watch in Galapagos, and are just one more reason to conserve this wonderful archipelago.
And then it was time to turn around and head back.
18 km / 11,18 miles (roundtrip)
I will not lie.
The hike back is long and hot. Even with an early morning started at 7:30 am, we were hiking up hill, on an unshaded trail, at the hottest point of the day. Granted, there is no real altitude to deal with but the hike is still a strenuous one and it is not recommended for young children or for adults who have not put in some hiking miles before visiting. And even when you got back to the crater rim at Sierra Negra and could once again see that glorious caldera spread out in the afternoon light, our hike was not done.
We might've been wishing for the clouds and a little rain to help cool things down for the last hour back down the mountain.
On the day we completed this hike, we were fortunate to go back the same way than we had climbed. It was raining with the slick mud that we hadn't faced on the uphill climb.
***
The hike Chico Volcán is normally combined with the day hike to Sierra Negra itself. In combination, the entire combined hike took about 5-6 hours to accomplish. Make sure to carry plenty of water, a high energy snack, and sun protection, especially a hat and sunglasses as the glare of the equatorial sun on the stark landscape is harsh. And take these things even when the day looks cloudy from your start point in Puerto Villamil.
The far side of Volcán Sierra Negra experiences a completely different weather pattern that is not easily guessed from the port town. If you’ve rented rain boots for the muddy trail up Volcán Sierra Negra, pack your hiking boots for the trail down the other side.

The guide released us to make our way back at our own pace, so I took the opportunity to run/jog and loosen my muscles (climbing 4 volcanos in the 4 days).
It was the eighth and last volcano on that trip. There are no more climbs.
I must have reached the starting point 45 minutes before everyone else. I took a nap.
Swimming (snorkeling) and hiking will start tomorrow.
Hike Sierra Negra and Chico Volcanoes,
This day tour explored the unique volcanic landscape of Isabela Island and the 2nd largest caldera in the world
I don't know what you think of when you think of the Galapagos, but giant volcanoes was one of the things that was in my head. This day tour (around $40-$60) took us to the second largest caldera in the world, and then explored the lava fields of Sierra Negra.
I was picked up at your hotel in town in the morning, and the drive to the island's interior to start our hike. After a long upwards grade on a wide trail, we reached a lookout point on the caldera's rim. It is MASSIVE. Too big to fit in a single picture massive. After snapping a couple pictures and stopping for a snack, we continued off the rim, and descended towards Volcan Chico. We left the more forested area and crossed a huge lava field towards the more recently active area. We saw the remnants of lava waterfalls, lava rivers, and where there were actual eruptions. It's quite an incredible landscape, more reminiscent of Iceland than the Galapagos!
***
The tour began by taking a 45 minute vehicle transport into the highlands until we reached the Galapagos National Park Control Point at 900 meters above sea level.
From there we ascended on foot for approximately 45 minutes until we reached the edge of the Sierra Negra caldera. The caldera landscape is mostly flat and we walked for approximately 1 hour around a section of the volcano edge.
Here we enjoyed our included lunch and then, we took the trail to Volcan Chico and the new trail recently opened by the Galapagos National Park to Sierra Negra Volcano’s last eruption site.
After that the transport picked us up to return to Puerto Villamil.
Teide National Park is centred on Mount Teide the highest mountain of Spain and is a UNESCO World Heritage Site. This is a view out across the petrified lava fields with the outer walls of the much older super volcano in the background and is known as Las Canadas caldera.This image is facing West from the Roques de Garcia across Llano de Ucanca.
Many thanks for taking the time to view this and other images in photo stream.
After a leisurely lunch in Castelmola, we went on a stroll around the town. This was a view I had to capture. Thanks for looking.
Mount Ruapehu, is the largest active volcano in New Zealand, it is the highest point on the North Island and has three major peaks.
The North Island's major ski resorts and only glaciers are on its slopes.
One of the Aeolian Islands in Tyrrhenian Sea, with live volcano in the middle of it. It is constantly active with minor eruptions. Intervals between eruptions range from a few minutes to a few hours. When we were there, it took about 25 mins between eruptions.
The plume of smoke doesn't seem to be big, but when we consider that Stromboli rises 926 m above sea level then we see that the plume is about I'd say 150-200m.

By clinging on to a metal rail on the edge of the viewpoint, I managed to exclude all of the hundreds of other people also taking shots of this scene. It was a dramatic sight!
Mt Tangkuban Perahu erupted in 1826, 1829, 1842, 1846, 1896, 1910, 1926, 1929, 1952, 1957, 1961, 1965, 1967, 1969, 1983, 2013 and 2019. This mountain and crater are located over the eastern perimeter of a major caldera which formed from a collapse after an eruption of its ancestral volcano, Mt Sunda.
I processed this Foto in Black&White due to the ominous beauty of an active volcano lording over the island of Japan.
This is the other side of the view from top of the Bromo crater. One of my favorite image from my visit here. Enjoy. :)
The mighty, the sacred, the eternally mysterious - central to the identity of Japan and her people.
For me, a pilgrimage of sorts; to finally stand before this most beautiful of natural wonders, a deeply moving 24 hours in my life. Fuji-san leaves one breathless and bewildered. Parting earth and sky with remarkable symmetry, its beauty beyond description in text or letter, no poem powerful enough to create the emotion in one's heart and mind upon seeing for the first time, in person and close at hand.
I arose the second morning at 5am to witness first light falling on the sleeping giant, and the sunrise upon Lake Kawaguchiko before me.

This shot here is a little while later - this wonderful view was enjoyed from our balcony with its own private onsen, at the Hotel Kukuna. Highly recommended.
Mount Fuji is an active stratovolcano and the tallest mountain in Japan, standing at 3,776 meters (12,380 feet).

Gunung Merapi is active, regularly erupting. It has a history of large, destructive eruptions and because of its proximity to densely populated areas, in particular Jogjakarta and the many towns and villages around it and acending its slopes, there have been tragedies that have taken human lives.
It is a stratovolcano and has had a variety of eruptions: basaltic lava flows (earliest), andesitic flows, ash eruptions, explosions, steam-blast eruptions (Phreatic), pyroclastic flows.
(Merapi = fire moutain)

Many thanks to all those who view, fav or comment my pictures. I very much appreciate it.
Just be silent
I can’t breathe,
If you please,
Let me go, let me be released.

This is a photograph of the actively volcanic islet called Nea Kammenē (aka Nea Kamenē, in Greek: Νέα Καμμένη) at sunset. The islet's area is 35,930 ft² (3.34 km²) and its peak is 417 ft (127 m) high; the islet lies to the West of Santorini (aka Thēra, Θήρα) Island. Thērasia Island is partly viewed in the background on the left. A smaller and older volcanic islet (Palaea Kammenē, on the left of this shot) lies further to the West of Nea Kammenē.
Nea Kammenē was formed by volcanic eruptions in the 1570s. Repeated volcanic activity occurred there again in 1707–1711, in 1866–1870, in 1925–1928, in 1939–1941 and in 1950. Mild volcanic activity has never ceased: the islet has been closely monitored by scientists as an active volcano and is usually daily visited by tourists in the summer.
The major volcanic eruption in the wider area probably took place on Thēra Isl. c.1615 BC according to radiocarbon dating; prior to the eruption the ancient island had been called “Strongylē” (Στρογγύλη meaning “Circular or Round one”) as well as “Kallistē” (Καλλίστη meaning “Most Beautiful”).
An appropriate name for an island that boasts the only confirmed active volcano in South Asia. We were on a fishing trip out of Havelock Island (another and larger island of the Andaman chain) when we decided to explore the seas around Barren Island. The fishing was pretty good but, by the end of the day, the whole boat was covered in black volcanic dust - and so were we!

Timanfaya (Fire Mountain) National Park on Lanzarote in the Canary Islands.
This is an active volcano. The heat coming off just nine layers of volcanic rocks is used to cook chicken, steaks and fish for tourists in the Restaurant at the Timanfaya Park.
I can remember taking a sunset trip around the park many years ago and after sunset the craters glow with the volcanic activity beneath giving the impression of being on another planet. The solidified, surface lava underfoot is very hot.
Organised coach trips can be made to travel around the volcanic area as driving by car is not allowed on the one-way route.
