Right away, retreats boring nerd travelling in Bali (8)

'bali' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'right away retreats boring nerd travelling' is the wordplay.
'right away' becomes 'asap' (I've seen this in another clue).
'retreats' says the letters should be written backwards (I've seen 'retreating' mean this).
'boring' means one lot of letters goes inside another (some letters must 'bore' a hole into other letters).
'travelling' indicates anagramming the letters.
'asap' written backwards gives 'pasa'.
'nerd' is an anagram of 'denr'.
'pasa' put within 'denr' is 'DENPASAR'.

'in' is the link.

Can you help me to learn more?
