Situated in St Johns the Tynwald National Park and Arboretum is set in more than 25 acres of picturesque countryside. The Park divides into 3 subsections. Phase 1, the vicinity of the pond and lower slopes, accommodates a wide range of less common largely ornamental trees and shrubs and is divided by grassed rides, each of which bears the name of one of the Island's 17 parishes.
Phase 2 covers rising ground to the north and east and accommodates hardier, mainly native tree species. A specially constructed shelter and picnic area commands a panoramic view extending westwards to the sea and south over the church and village to tree-clad Slieau Whallian.
