Fossil Walks, Dublin coast, 23 May
This Biodiversity Week, join us for a walk through millions of years along Dublin's coastline, between Portmarnock and Malahide. Together we will go fossil hunting!
This event is open to children and adults - booking essential as spaces are limited.
What people are saying:
"We had a very enjoyable & informative walk along the beach in Portmarnock with Anthea on Sunday. She opened our eyes to the fossils in the rocks which we had never noticed before. Anthea patiently explained how it came about & what to look for. A young member in the group became an "expert" at spotting beautiful examples in the rocks. We are looking forward to joining her on future walks." Peter Curran, Facebook review

What people are saying
“Anthea is a wonderful leader, navigating the glorious Wicklow Mountains with consumate ease while sharing her extensive knowledge of the geology and ecology of the area. The pace of trek and of delivery was perfect. I cannot recommend this experience highly enough and have already begun arrangements to join Anthea again soon.”
— Martina Clancy, Trustpilot
“I have hiked with Anthea on lots of occasions. Every single time she planned everything meticulously and organised everything, from trails to accommodation. All I needed to do was show up. Anthea possesses a wealth of knowledge about the natural world, always teaching and disseminating insights on plants, birds and of course, geology. The paces of her hikes are tailored to the needs and ability of the group she is guiding. Always proactive, her ability to replan in no time at all due to changes in weather adds to her already fantastic attributes as a guide. She even had extra waterproof pants for all of us! I cannot recommend Anthea highly enough. Book with her for an experience of a lifetime.”
— Halleluya Ekandjo
