All this will cost you is the bus fare to its location in Glasnevin -- it's a treat for the senses with hundreds of different types of flowers and plants on display.
Stroll and sit along the water in Portobello -- bonus points if you find the bench occupied by a statue of poet Patrick Kavanagh.
The Irish Museum of Modern Art is as famous for its outdoor gardens as the art that hangs inside on the walls. Entry is free in any case, so you can enjoy both!
