Coastal Heritage Guide

Making Coastal Walks Accessible for Everyone

I help seniors and mobility-limited visitors confidently explore Dublin's harbour landscapes—from Howth's dramatic cliffs to seal-watching points that actually work for older bodies.

How I Got Here

From Glacial Geology to Guided Walks

I started out as a field researcher. During my postgraduate work at Trinity College Dublin, I was mapping coastal erosion patterns along the Dublin coastline—measuring cliffs, tracking sediment movement, studying how the landscape changes over seasons. It was fascinating work. But honestly, I spent most of my time alone with measuring tapes and notebooks.

The real turning point came when I started volunteering with a local seniors group. They wanted to walk Howth's coastal paths, but couldn't find anyone willing to show them routes that didn't involve steep scrambles or unmarked trails. I took a few of them out—maybe eight people—and something clicked. They weren't just getting exercise. They were learning the landscape's history, spotting seals they'd never seen before, reconnecting with a place they thought was closed off to them.

That was 14 years ago. I've now led over 3,000 guided walks along Dublin's coastline, spent five years doing monthly monitoring visits to Howth tracking seasonal seal populations and route conditions, and worked with accessibility advocates to document which paths actually work for people with mobility limitations. The geology degree still matters—people want to understand why these cliffs exist, what the rocks tell us, why seals choose certain viewing points. But it's really about access. Making sure that age or mobility doesn't mean exclusion from the landscape.

2010

University Years Begin

Completed degree in Environmental Science at University College Dublin, developing early interest in Dublin's geological landscape.

2012

Postgraduate Research

Earned postgraduate qualification in Geomorphology from Trinity College Dublin, focusing on coastal erosion patterns.

2013

First Guided Walk

Volunteered with seniors group, discovering the intersection of coastal expertise and accessible tourism. That group of eight changed everything.

2019

Howth Deep Dive

Began monthly monitoring visits to Howth, documenting seasonal seal populations, geological features, and detailed route accessibility data.

2024

Saniashares Digital Ltd

Joined saniashares Digital Ltd as Senior Coastal Heritage Guide, translating 14 years of fieldwork into accessible, research-backed content for older adults exploring Dublin's coastline.

What I Know

Specialised Knowledge in Coastal Access

Over 14 years of fieldwork, research, and hands-on experience across Dublin's harbour landscapes.

Route Assessment & Documentation

Detailed knowledge of every major coastal walk around Dublin. I've personally assessed path conditions, identified safe alternatives, and mapped accessibility barriers for routes from Howth to Dun Laoghaire.

Marine Wildlife & Seal Behaviour

Five years of monthly monitoring visits to Howth documenting seal populations, seasonal patterns, and best viewing points. I know when and where you'll actually see them—and when you won't.

Coastal Geology & Landscape History

Postgraduate qualification in Geomorphology. I can explain why Dublin's cliffs exist, what the rock formations tell us about Ice Age glaciation, and how the landscape continues to change.

Accessibility & Senior-Friendly Design

Over 3,000 guided walks with older adults and mobility-limited visitors. I know what actually works—rest points, pace, surface conditions, realistic timeframes, and modifications that maintain the experience's value.

Heritage Interpretation

Making landscapes meaningful. I've developed methods for explaining geological, historical, and ecological features in ways that engage older visitors without oversimplifying complex natural processes.

Senior Community Connections

Extensive network across Dublin's retirement organisations, senior centres, and accessibility advocates. I understand the real barriers older adults face when planning outdoor activities.

My Approach

Why I Do This Work

Access Isn't Optional

Age or mobility limitations shouldn't mean exclusion from Dublin's most beautiful landscapes. The coastline belongs to everyone. My job is making sure everyone can actually access it safely—without compromising on the real experience or dumbing down the geology, history, and wildlife we're seeing.

Evidence Over Assumptions

I don't guess about what works. Every route recommendation comes from actual fieldwork. Every accessibility claim is based on repeated visits under different conditions. Every detail about seals or geology is documented and verified. That's why my advice is reliable—it's not marketing. It's what I've learned doing this work.

People First, Landscape Second

I'm passionate about the landscape, but genuinely passionate about people experiencing it. That means being honest about difficulty levels, realistic about timeframes, and designing walks that leave people feeling accomplished—not exhausted or injured. The geology can wait. Getting people safely into the space matters more.
