The structure consists of a circular earthen ring with a diameter of 180 m and an area of 28,000 square meters, surrounded by an earthen rampart 3.5 m high. At least three of the five irregularly distributed gaps in the ring are intentional and possibly original. East of the center of the ring is a small passage grave with a westward-facing entrance.

The park covers almost 130 hectares and offers a variety of landscapes - from wide meadows and shady woodlands to manicured rose and Japanese gardens. The International Rose Trials, which take place here every year, are particularly exciting. If you come at the right time, you can admire an impressive variety of roses, which are judged by international experts. But the park has a lot to offer away from the roses in bloom: whether you just want to take a quiet walk in the Walled Garden, explore the Japanese Garden or challenge yourself on the orienteering course - everyone will find a favorite spot here. A small café provides refreshments and the playground also has something for younger visitors. The park has many hidden corners that make it an ideal stop to recharge.

As you get closer, the mystical aura of the place unfolds, with its mighty, almost circular earthen wall, which measures over 180 meters in diameter and dominates the view over the surrounding plateau. This ancient henge complex is one of the largest and best-preserved monuments of its kind in Ireland - hard to miss when you get close to Shaw's Bridge. In the center of the ring, a megalithic tomb awaits you, which tells its own story with its five supporting stones and a mighty capstone. You can literally feel the thousands of years that have passed here since ceremonies and gatherings probably took place at this place. It is impressive how the Giant's Ring has survived over time, while the wooden structures of the Ballynahatty settlements are long gone.

This nature reserve is located in the heart of the busy Belfast Harbour Estate and offers a welcome break from the hustle and bustle of the city. On the way there, the route takes you along the lough, where you may be lucky enough to spot various species of birds. The centre itself has two observation huts and a modern visitor area with panoramic views of the lagoon. Here you can enjoy the diverse wildlife while enjoying a cup of coffee. However, the paths to the centre are sometimes muddy in wet weather, so sturdy shoes are recommended. Overall, the RSPB Window on Wildlife Centre is a worthwhile stop on your bike tour to experience nature and peace.

With thousands of colourful flowers and plant species from around the world, the Botanic Gardens are a wonderful place to visit. The gardens opened in 1828 as a private park and welcomed the public from 1895. Belfast's beautiful Palm House conservatory pre-date the glasshouses of Kew Gardens. Its domed roof has allowed plants to grow especially tall, such as a 36-foot (11 m) lily.
