This is a really lovely park, on the outskirts of Leeds. We were in Leeds for the day, and got the bus to the park no problem. Buses 2 & 12 both go from the city centre to the park every ten minutes or so.
There are gardens, and a lake, and on a summer’s day, it’s just such a pleasant place for a stroll.
Don’t miss Tropical World while you are here, as that, for me, is the jewel in the crown of Roundhay Park.
