GeoWorld Travel

GeoWorld Travel GeoWorld Travel offers geology tours to some of the world’s most interesting geosites. Many tours are led by founder James Cresswell.

Tours are suitable for beginners, enthusiasts and experts alike, with the scenery explained in an accessible way. Geotourism is more than just the rocks
and ice, it is about experiencing the whole geodiversity
of a destination, which includes its biology and history
too. Spectacular scenery normally goes hand in hand with
incredible wildlife and fascinating human stories and our trips
combine all of these things. Travel with GeoWorld and gain something extra: All our trips are
guided by an experienced Geologist. On one of our trips you will see
the wildlife and historical sites that you may expect to see on other
trips, but in addition you will have the geology and scenary explained
to you. GeoWorld’s trips are currently run in the Polar regions and
Wales, but will soon be expanding to offer trips to other destinations
such as the Pyrenees, Canadian Rockies, Galapagos, Iceland and East Africa.

🌍 Can you really stand between two continents in Iceland?

At Iceland’s famous Bridge Between Continents, you are within the boundary zone where the North American and Eurasian tectonic plates are pulling apart.

But, as James explains in this reel, the geology is a little more complicated than the name suggests. The bridge itself does not cross a single neat line separating the two plates. Instead, it spans a huge extension fracture within a much wider rift zone.

And it is quite a fracture. This is one of the widest extension fractures in Iceland, created as the crust is gradually stretched apart. 🌋

It is a brilliant example of geotourism making an enormous geological process visible on a human scale, and exactly the sort of thing we love exploring on a GeoWorld Travel tour.

🇮🇸 We recently got back from another fantastic circuit of Iceland - a trip of volcanoes, glaciers, waterfalls, lava fields, geothermal areas, black-sand beaches, improbable geology and some very changeable weather! We crossed the island from the Reykjanes eruptions to Askja and Mývatn, visited the Westman Islands and Vatnajökull, stood on young lava, old lava and rather a lot of pumice, and somehow managed to see the Northern Lights on three consecutive nights.
📸 Here are 40 photographs from the trip, with a little of the geology behind what we were looking at.
📩 We'll be back in Iceland in 2027 (trip already fully booked), but we're starting to plan for 2028, so if these photos inspire you to join us, please do get in touch to register your interest...

What happens when two different magmas meet beneath a volcano? 🌋🪨

James is in East Iceland, near Vestrahorn, looking at the famous net vein complex, where the evidence is right there in the rock.

Here, pale, silica rich granophyre magma forced its way into darker microgabbro, fracturing it and carrying pieces of the original rock within it. In places, the gabbro was even partially melted and absorbed.

What we are seeing is evidence of two different magmas interacting deep underground.

These rocks are around five million years old, relatively old by Icelandic standards. Millions of years of erosion have stripped away the volcanic material that once covered them, revealing what was happening deep inside an ancient volcanic system.

It is almost like being able to look inside a fossilised magma chamber.

This fold is measured in kilometres, not metres.

In Wadi Mayh, Oman, James is standing beside an enormous fold created by some truly immense geological forces.

These rocks began as sediments on the continental margin of Arabia. They were carried down into a subduction zone before eventually being forced back towards the surface, deforming and folding the rock on a huge scale in the process.

And what you see behind James is only part of it. The structure continues beneath the road and into the rocks on the other side.

A brilliant example of just how enormous geological structures can be when you get the chance to see them in the landscape.

Morocco: The Trilobite’s Sahara Kingdom

At the end of 2025, we completed our tenth GeoWorld Travel adventure through Morocco, and what a trip it was!

Over 11 days we travelled from Marrakech across the High Atlas Mountains, through the fossil-rich Anti-Atlas and onwards to the edge of the Sahara.

🦖 Dinosaur fossils and trackways
🪨 Trilobites, orthoceras and goniatites
⛏️ Fossil quarries and mineral mines
🏔️ Enormous folds, faults and mountain landscapes
🏜️ The spectacular dunes of Erg Chebbi

Swipe through for just a taste of the adventure, then head over to our latest photo diary where we’ve selected 50 of our favourite photographs from the trip.

Read it here: https://geoworldtraveldiaries.com/2026/09/14/morocco-2025-the-trilobites-sahara-kingdom/

Morocco remains one of our favourite destinations for experiencing geology and palaeontology in the field, and after ten trips, there is still so much to discover.

Imagine standing where an ancient subduction zone once existed.

James describes this as one of his favourite stops in Oman, and it is easy to understand why. From this single viewpoint, you can piece together an extraordinary part of the region’s geological story.

The rocks beneath James formed on the ancient continental margin of Arabia, while the mountains behind him contain rocks that originated in the Earth’s mantle. During the Cretaceous, this was all happening beneath the ocean as crust was dragged down into a subduction zone.

Today, it is high above sea level and forming mountains as the region continues to be uplifted.

A remarkable amount of Earth history visible from one spot.

35km beneath the surface, then back up again.

In this reel, James is in Ruwi, Muscat, exploring rocks that have been on quite a journey.

The rocks here were dragged around 35km beneath the surface as continental crust was subducted beneath the Semail Ophiolite. They were then forced back towards the surface, creating the shear bands James and the GeoWorld Travel group are examining.

They also contain minerals including lawsonite and carpholite, clues to the immense pressures these rocks experienced deep underground.

Another brilliant example of being able to stand in front of a rock face and unravel an extraordinary chapter of Earth’s history.

Standing on the edge of Oman’s “Grand Canyon” at Wadi Al Nakhur, with Jebel Shams rising behind.

This immense landscape cuts through millions of years of geological history, exposing Cretaceous sedimentary rocks and older Jurassic layers below, before the dramatic emplacement of the Semail Ophiolite transformed the region.

It’s one of those places where the scale is difficult to appreciate until you’re actually standing there.

Geology written on a colossal scale.

Oman is just so full of geological outcrops!
