Her Story
From Volunteer to Senior Hiking Specialist
How It Started
Síobhan's passion for senior-focused hiking began in 2010 when she volunteered with the Irish National Parks and Wildlife Service. She was leading nature walks for a local retirement centre in Cork — simple weekend activities at first. But something clicked. She noticed how much people aged 60+ actually wanted to explore Ireland's landscapes, yet so few trails were designed with their needs in mind.
Education & Credentials
She earned her degree in Environmental Management from University College Cork in 2012. But the real learning came after. She pursued formal training in inclusive outdoor recreation, completed advanced certifications in outdoor leadership, and spent years studying how to adapt trails for different abilities. It's not just about knowing the landscape — it's about understanding how age, fitness levels, and individual needs shape the hiking experience.
Building a Methodology
Over 14 years, she's developed detailed route assessments for trails across Killarney National Park, the Burren Way, and Glendalough Valley. These aren't casual observations. She evaluates gradient, surface conditions, rest points, accessibility facilities, and seasonal variations. Each trail gets mapped with specific considerations: Where can someone with joint pain stop comfortably? Which paths have good shade for warmer days? Where's the nearest water source? This methodical approach has shaped how she guides walkers today.
Philosophy & Vision
Síobhan's core belief is straightforward: age shouldn't limit outdoor exploration. But it requires thoughtful planning and expert guidance. She's trained over 40 hiking guides in accessibility practices and regularly consults with Irish tourism boards on senior-friendly trail development. At nm-nanomed Two Ltd, she combines her deep knowledge of Irish terrain with evidence-based practices in senior fitness and wellbeing. Her work proves that Ireland's natural beauty belongs to everyone — you just need the right guide to unlock it.
