Wicklow’s Best Woodland Trails for Crisp Autumn Mornings

When the September morning air gets crisp, there is no better place to be than under a canopy of changing leaves. Wicklow’s native woodlands come alive with rich gold, amber, and bronze tones. Here are three unmissable forest walks to try this month.

1. Devil’s Glen Forest Park

• The Vibe: Dramatic, artistic, and deeply atmospheric.
• The Trail: The Seamus Heaney Walk or the Waterfall Walk.
• Highlight: A spectacular gorge where the Vartry River thunders down a 100-foot drop, surrounded by unique sculptures hidden among the trees.

2. Tomnafinnoge Woods

• The Vibe: Ancient, peaceful, and rich in heritage.
• The Trail: The linear riverside walk or the main oak loop.
• Highlight: This is one of the last remaining ancient oak woods in Ireland. Walking here feels like stepping back in time as the sunlight filters through massive canopy trees.

3. Avondale Forest Park

• The Vibe: Modern, family-friendly, and grand.
• The Trail: The Centenary Trail or a walk down to the Avonmore River.
• Highlight: Home to the Beyond the Trees Avondale experience, featuring a massive treetop walk and a 38-metre viewing tower offering panoramic autumn views across the entire vale of Avondale.

A Wicklow Day Trip: The Spinc Loop Boardwalk Hike at Glendalough

For the ultimate active day trip, head to the historic valley of Glendalough. While the monastic city is beautiful, the true magic lies high above the Upper Lake on the famous Spinc Loop.

• The Vibe: A strenuous but highly rewarding 9.5km loop that takes roughly 3 to 4 hours.
• The Trail: A steep climb up wooden steps brings you to a magnificent wooden boardwalk that runs right along the ridge of the mountain.
• Highlight: Dramatic, vertical lookdowns over the deep blue waters of the Glendalough Upper Lake, the old miners’ village, and the surrounding mountainside turning shades of gold.

The Wicklow Head Lighthouse & Cliff Walk

For visitors looking for crisp coastal air rather than mountain mist, the rugged trails around Wicklow head offer an incredible alternative.

• The Vibe: Dramatic coastal cliffs, maritime history, and active marine wildlife.
• The Trail: This trail loops past three historic, iconic lighthouses.
•  Highlight: These paths offer a peaceful escape from busier inland trails, leaving the jagged cliffs, the Black Castle ruins, and crashing waves completely undisturbed. The refreshing sea air makes this a premier location for spotting grey seals on the rocky shelves below.

Ballinastoe Woods: The Fairytale Boardwalk

Located right near the Sally Gap route, this forest is famous for its atmospheric, moody, and almost mystical aesthetics.

• The Vibe: Deep, enchanting evergreen forests that feel straight out of a fantasy novel.
• The Trail: A tight canvas of towering evergreens where moss carpet covers everything. The highlight is the wooden boardwalk cutting through the dense, dark trees.
• Highlight: Head here for an early morning walk when the low sun cuts through the dense tree canopy, creating spectacular shafts of light (komorebi) filtering through the early morning mist. It pairs perfectly with a drive past Lough Tay.

The Maple Walk at Mount Usher Gardens

For a gentler, world-class horticultural stroll,  Mount Usher Gardens in Ashford is unmissable as the foliage begins to turn.

• The Vibe: Tranquil, romantic, and bursting with curated botanical colour.
• The Trail: 22 acres of wild-style gardens tracing the path of the Vartry River. Pick up a tree trail map at entry to locate their rare, global species.
• Highlight: The dedicated Maple Walk showcases a spectacular transformation as the Japanese Maples and Golden Larch erupt into a brilliant blaze of fiery reds, rich ambers, and golds. Afterward, visitors can warm up with a hot drink at the on-site Avoca Garden Café.

The Vale of Clara Forest Walk

Tucked away between Laragh and Rathdrum, this is one of Ireland’s quietest and most pristine native woodlands.

• The Vibe: Soothing, serene, and perfect for a peaceful family walk.
• The Trail: The trail follows the gentle, murmuring flow of the Avonmore River under a heavy canopy of ancient native oak trees.
• Highlight: It offers the ultimate crisp morning forest experience. Because it is less frequented than nearby Glendalough, you can enjoy the rare, peaceful silence broken only by the satisfying crunch of fallen leaves under your boots.

Blessington Greenway

• The Vibe: A quiet, meditative energy fills the shoreline as summer crowds thin, leaving only the sound of lapping water, crunching leaves, and a warm, golden autumn glow.
• The Trail: A flat, beautifully maintained mixture of boardwalk and gravel paths that winds from the town to Russborough House, tucked under a natural stained-glass canopy of amber and bronze leaves.
• Highlight: The water’s edge, where the glassy reservoir acts as a flawless mirror, reflecting the mist-shrouded Wicklow Mountains and the brilliant, contrasting autumn colours of the forestry.
