The Howth Cliff Walk is a scenic coastal trail along the eastern edge of the Howth Head peninsula, about 30 minutes from Dublin city center by DART train. The loop trail runs roughly 8 kilometers and takes about 2 hours to complete at a moderate pace. Walkers pass dramatic sea cliffs, heather-covered hillsides, and views of Ireland's Eye island and Dublin Bay.

After the walk, Howth village offers seafood restaurants, pubs, and a working fishing harbor worth exploring. The trail is free to access and open year-round, though weather can shift quickly, so layers are a good idea regardless of the season.

The trail starts with a short walk from Howth DART station through the village, before the path begins to climb and the true coastal section starts.

Parking is available in Howth village if arriving by car.

Bushy Park is a 74-acre public park in Terenure, south Dublin, offering a quiet escape from the city.

The park is threaded with informal paths that wind through mature woodland, open meadows, and along the River Dodder. Some of these routes are unmarked, rewarding explorers who stray from the main walkways.

The grounds also include ponds, sports pitches, a playground, and a small café near the entrance. Entry is free, and the park is open year-round.
