Barra Best is in his home town of Belfast, where he takes a boat ride through the busy docks with Dr Justin Judge, a local marine biologist. They search for a local colony of seals who have made their home on the banks. Barra is blown away by the number of seals and their closeness to the city centre.Barra has his walking boots on and is in the heart of Cave Hill with Anwar Akuri, who takes walking groups to many parts of the city for exercise, health and well-being. He learns a lot about Anwar and about Yemen, the country he came from. Barra also gets a surprise in Colin Glen forest park, where he gets a ride on Ireland's longest zip wire.The last trip in Belfast is to the Slievenacloy nature reserve, where he meets ranger Ronald Surgeoner. Barra is surprised to hear that there are lizards in Belfast. After he and Ronald repair some fences, they search for the tiny creatures, and Barra cannot believe his luck when he spots one through his binoculars.
