Good ramble in wood (5)
I believe the answer is:
grove
'wood' is the definition.
(grove is a kind of wood)
'good ramble' is the wordplay.
'good' becomes 'g' (abbreviation).
'ramble' becomes 'rove' ('rove' can be a synonym of 'ramble').
'g'+'rove'='GROVE'
'in' is the link.
(Other definitions for grove that I've seen before include "small plantation" , "Small growth of trees" , "Wood of small size" , "Hurst" , "Writer on music" .)
