The Story Behind the Routes

How a childhood passion became a career dedicated to making island walking accessible for everyone.

Growing Up on the Islands

Siobhan grew up in West Cork, where her childhood summers were spent exploring the smaller islands off the Munster coast with her grandparents. Those early experiences — navigating rocky paths, discovering hidden coves, understanding how weather shapes coastal landscapes — shaped everything she'd later do professionally. She wasn't just hiking. She was learning how the land works, how to read terrain, and most importantly, how to move through it safely regardless of age or fitness level.

From Tourism to Accessibility

After completing her geography degree at UCC in 2008, she initially worked for the Irish Tourism Board. Thing is, she felt something was missing. The hiking guides available to visitors weren't adequately serving older people. They either treated every route as equally accessible or avoided catering to older adults entirely. Siobhan saw a gap — and she knew exactly how to fill it.

Systematic Mapping and Field Work

In 2012, she began systematically mapping accessible routes on Inis Mór, Dursey Island, and Sherkin Island. But here's what made her work different: she didn't just rate difficulty. She conducted accessibility audits that included rest points, terrain types, weather exposure, nearby amenities, and practical considerations that actually matter to older hikers. Every route assessment came from real fieldwork — she walked each path multiple times, in different seasons, at different times of day. She tested them with people of varying mobility levels.

Recognition and Speaking

Her breakthrough came when the Irish Independent featured her detailed Inis Mór guides. Suddenly, she was receiving invitations to speak at retirement communities and hiking clubs across Connacht and Munster. Older adults were reading her work and discovering that island walking wasn't reserved for the young and athletic. What started as a personal mission became a recognized expertise.

What Drives Her Work Today

Siobhan approaches each route with the conviction that accessibility should never mean compromising on beauty or authenticity. She's witnessed older adults regain confidence on trails. She's seen people discover that retirement isn't the end of adventure — it's just a different kind of adventure. That's what keeps her documenting new routes, refining existing assessments, and pushing for better island infrastructure that serves everyone. At varitru Limited, she brings both fieldwork expertise and a deep understanding of the physical and practical needs of older hikers who want to experience Ireland's islands properly.
