Scottish Geologist on TikTok

What it is

@scottishgeologist is the TikTok of Luisa Hendry, a Glasgow-trained geologist who calls herself "that girl that makes videos about rocks." Her website, scottishgeologist.co.uk, offers geology tours across Scotland (Skye, the North West Highlands, Mull, Iona and Staffa, Shetland) plus shorter day walks, but on TikTok the rocks themselves are the point. When we checked, the account had about 77,000 followers and 1.7 million likes.

Videos are short, in English and filmed at the places she talks about, explaining what's under your feet and how it got there.

Why we picked it

It changes how you see places you thought you knew. Arthur's Seat in Edinburgh turns out to be the remains of a volcano active around 340 million years ago, in the Carboniferous. The Highland Boundary Fault runs right across Loch Lomond, and in her video you can actually see the line where the Highlands begin. And the reason some grass in the North West Highlands is so startlingly green? The pale rocks of the Durness Group underneath.

She's just as good on smaller-scale geology: boudinage, where rock has been stretched into pieces deep in the crust, in the ancient Lewisian; pegmatite with enormous K-feldspar crystals and why they grow that big. One of our favourites is a mini-rant after a boat cruise through the Great Glen, where the commentary covered history and scenery but never mentioned the fault that made the glen in the first place.

In October 2026 she announced she'd become a Geological Society of America ambassador, so expect some geology from beyond Scotland too.

The filming helps a lot. Nearly every video is a real spot you can find on a map: a hillside, a shoreline, a lay-by. She points out what to look for and only then gives you the term. Captions are detailed, often a full paragraph with the age of the rocks and how they formed, so the feed doubles as a field guide to places where Scottish geology is visible to the naked eye.

Where to start

• The Arthur's Seat video on Edinburgh's volcanic past.
• The Highland Boundary Fault crossing Loch Lomond.
• "Why is the grass SO green here?" from the North West Highlands.
• Pegmatite and its giant crystals.
• Dinosaur footprints on the Isle of Skye.

Who it's for

Anyone planning a trip to Scotland who wants to see more than pretty hills. Students who find textbook geology a wall of jargon. Beachcombers who pick up stones and want to know what they're holding. Teachers looking for real-world examples filmed on location.

Quick answers

Is it just an advert for her tours? She mentions her tours now and then, but the feed is built around explaining geology.

Is it only Scotland? Mostly, though from autumn 2026 she's also covering US trips as a GSA ambassador.

How often does she post? Several times a month in late summer and autumn 2026, after a quieter spring.
