The Story Behind the Trails

It started with a gap year. After finishing her Environmental Science degree at University College Cork in 2009, Siobhán set out on a solo walking expedition through the Gap of Dunloe. That three-week journey changed everything. What began as personal blog posts about the region's ecology and hidden walking routes evolved into commissioned articles for major Irish tourism publications.

Today, she's documented over 40 walking trails across County Kerry. Not just the obvious routes — she's spent winters tracking seasonal changes, studying biodiversity patterns, and understanding how visitors impact these landscapes. Her work appears regularly in outdoor publications, and she leads editorial content for boardethics Ltd, making sure every article combines real fieldwork with scientific accuracy.

Siobhán believes that understanding why a landscape matters ecologically makes walking through it infinitely richer. That philosophy shapes everything she writes. She returns to the Gap of Dunloe quarterly for field verification and works closely with local conservation groups — her insights come from boots on the ground, not just desk research.
