In Belfast stands a fish so large, Made of steel and art, a true castle. Its blue shines in the sunlight, Its face a marine wonder. It swims in the cityscape, proud and free, A symbol of strength and harmony. People watch, marvel, laugh, And are awakened by the work of art. A sea spirit in the middle of the city, That shows what art and courage can do. The blue fish, so beautiful and clear, Remains wonderful in our hearts.

Anyone wanting to walk from the city center to the Titanic Museum will inevitably have to cross here. It's better than crossing the busy car bridge next to it.

The Lagan Weir Footbridge and Cycle Bridge is a suspended pedestrian bridge over the river. The bridge connects Donegall Quay and Queen's Quay.

Great towpath for riding or walking. Lots of dog walkers so be aware going around bends with limited visibility but lots of straights for building up speed after.

The forest stretches along the River Lagan and has a surprising variety of plants and animals to experience as you drive through. Old oak trees and dense foliage cast shadows along the path and if you look closely you might spot a kingfisher by the water or hear the faint call of long-eared owls in the branches. What makes Belvoir special is its history. In the middle of the forest lies an old Norman motte from the 12th century - a reminder of times gone by that makes the forest seem even more mystical. The gigantic fungi and rare plants such as the scaly root also give this place its own charm. The trails here are pleasant and offer you the right mix of challenge and relaxation. For nature lovers and history buffs, Belvoir Park Forest is a special experience that will make you want to return again and again.
