Always pleased to get close to large swampy area (9)
I believe the answer is:
everglade
'swampy area' is the definition.
'always pleased to get close to large' is the wordplay.
'always' becomes 'ever' ('ever' can be a synonym of 'always'**).
'pleased' becomes 'glad' ('glad' can be similar in meaning to 'pleased').
'to get' is a charade indicator (letters next to each other).
'close to' suggests the final letters (the close/ending of).
The final letter of 'large' is 'e'.
'ever'+'glad'+'e'='EVERGLADE'
(Other definitions for everglade that I've seen before include "Swamp (in Florida, e.g.)" , "stretch of marshy grassland" , "nickname of US State" .)
