Landed safely and cleared the airport. We are on our way, ETA 4.00pm at school. Please keep the bus bay clear for the coach. See you all soon!

All on board and ready to depart! We will update parents of an ETA back at school once we have cleared baggage reclaim. #iceland25

All eyes to the north tonight 👀 A Coronal Mass Ejection is forecast to arrive on earth, potentially giving opportunities to see the Northern Lights. Strong auroral activity is possible in northern Scotland, but even southern England could catch a glimpse in any cloud breaks.

...and what a display we had 😍 #iceland25

Well, it was worth hanging on on sub zero temperatures for the Northern Lights... #iceland25

The Lava Show was new to the itinerary this year - and absolutely outstanding. Wow. #iceland25

Final stop on the South Shore Tour at Waterfall #2 - Seljalandsfoss, where conditions allowed us to experience the walk behind. You can only get so wet! #iceland25

Heading back to Reykjavik from the South Shore via a couple of waterfalls, starting with 60m high Skogafoss - it is surprising how many of our students were unaware that waterfalls and rivers will make them wet.... #learningpoint #iceland25

A brief stop at Reynisfjara Beach to admire the granite columns and black volcanic sand whilst avoiding the creeper waves #itsathing #iceland25

Always the highlight from our point of view, three hours exploring the Sólheimajökull Glacier. Phenomenal Weather #iceland25

Heading for Sólheimajökull... #iceland25

I think we may have worn them out... #iceland25

Beautiful weather this morning in Reykjavík ahead of our South Shore Tour, the wind has dropped and the sun is out. Time to go hike a glacier! #iceland25

Dinner at the Hard Rock Cafe - a lot of empty plates after our exertions today....! #iceland25

Final stop at Thingvellir National Park on the edge of the North American Plate looking across Lake Pingvallavatn to the edge of the Eurasian Plate #iceland25

Penultimate stop of the day at the Haukadalur Geothermal area where we waited 16 minutes to catch the Strokkur Geyser in action - it usually erupts every 6-10 minutes... #iceland25

A cold, wet and windy Gulfoss where the Hvita River plunges 33m in two stages into a 2.5km long canyon #iceland25

Stopping for lunch at the 55m deep, 6,500year old Kerrid Crater with its vibrant red volcanic rock. #iceland25

New to the trip this year, a fascinating hour spent exploring the Raufarhólshellir Lava Tunnel, learning about its formation #iceland25

First stop this morning is the Geothermal Exhibition at Hellisheiðarvirkjun to learn about how Iceland takes advantage of its inner heat to generate power and hot water #iceland25
