The National Botanic Gardens features on RTÉ’s popular Tracks and Trails this Friday night (28th February) at 7.30pm. Broadcaster Jim Sherwin chooses a walk starting at the Bull Wall in Clontarf in his native Dublin, where he travels along the coastal road before moving inland. He traverses the north side of the city to the Casino in Marino before travelling on to the National Botanic Gardens where he meets curator Paul Maher and others.
