How to Start Your Journey

Why not start early, just after breakfast! Hire a bike locally and make your way through town towards St. Mary’s Cathedral. Opposite the Cathedral you’ll find the Knockreer entrance to Killarney National Park, and from here an entire world of trails, woodland, lakeside scenery and wildlife opens before you.

Before setting off, take note of Deenagh Lodge, located near the entrance. Open during the summer season, this unique café and training facility is operated by Kerry Parents and Friends Association, providing valuable work experience and social opportunities for young people with Down Syndrome. It’s one of Killarney’s most heart warming attractions and a wonderful place to stop for refreshments on your return journey.

One of the joys of this part of Killarney National Park is that there is no single route. From the entrance, you can choose from a network of gentle cycling paths suitable for all ages and abilities.

How to Find the Playground

Just before Deenagh Lodge take a right, and you’ll pass the Knockreer Playground before following a scenic route towards Fossa, with the option of continuing all the way to the Gap of Dunloe if you’re feeling adventurous. You can always return to the Deenagh Lodge area before continuing on with your trip towards Ross Castle.

Take an Uphill Route for the Views!

If you fancy a little challenge take the path towards Knockreer House. Although the house itself is not open to the public, the surrounding gardens, mature woodlands and beautifully landscaped grounds are well worth exploring. From higher points along the route you’ll enjoy magnificent views across the park and towards the mountains.

Wildlife, Views and Peaceful Nature Trails

Cycling or walking westwards through the park, you’ll travel alongside open meadows, woodland and the edge of the golf course, with opportunities to connect to routes leading towards Killarney Golf & Fishing Club. Along the way, the peaceful Deenagh River accompanies much of your journey as it winds its way towards Lough Leane.

This is a route where the journey itself is the attraction. Deer graze quietly in the fields, ducks paddle through the river, birdsong fills the woods and every bend reveals a new view. Children will find endless reasons to stop, whether it’s watching wildlife, skipping stones across the water or simply taking in the scenery. 

Discover Ross Castle and Lough Leane

As you continue southwest, the path naturally leads towards Ross Castle on the shores of Lough Leane. Along the way, you’ll enjoy wide-open views across the lake, glimpses back towards Killarney House and Gardens, and occasional sightings of Ross Castle framed through the trees.

Ross Castle is an ideal destination and a central hub for exploring the Lakes of Killarney. During the visitor season, the castle itself is open for tours, while the surrounding area offers a range of lake and outdoor experiences. Boat cruises regularly depart from the pier, including scenic trips across Lough Leane and out to Innisfallen Island, offering a unique perspective on the National Park from the water.

Accessibility on the Lake

Among the operators based here, Ross Castle Boat Tours is particularly notable for its accessible experiences, with wheelchair-friendly options and inclusive, autism-friendly approaches that make the lake more welcoming for a wider range of visitors. Additional activities in the area include kayaking, traditional jaunting car rides, and guided lake excursions, ensuring there are options to suit different interests and abilities without overwhelming the visitor with choice.

The area also provides access to Ross Island and its historic Bronze Age Copper Mines, adding a further layer of heritage and discovery to a visit here.

A Flexible Day Out For All

The beauty of this cycle is its flexibility. You can complete a gentle half-hour loop, spend a relaxed morning exploring, or turn it into a full-day adventure combining cycling, walking, boat trips, wildlife watching and historic attractions.

However long you choose to stay, this corner of Killarney National Park has a remarkable way of rewarding every visitor. It’s a place where every path offers something different, and where every return visit reveals something new.

Whether you are travelling with children, planning a relaxed outdoor day or looking to discover a different side of Killarney, starting your journey from the Knockreer entrance gives you endless opportunities to explore.

Pack a picnic, bring your camera and take your time — because some of Kerry’s best experiences happen when you slow down and simply follow the trails.
