The walk at sunset was true bliss.
To emphasize the intensity of the feeling, 'Wonne' (bliss) is often combined with the adjectives 'rein' (pure) or 'wahr' (true). A very common phrase is 'Es ist eine reine/wahre Wonne, ...' (It is pure/true bliss to ...), followed by an infinitive with 'zu' (to).

It is pure bliss to listen to you making music.
The idiom 'seine helle Wonne haben' (to take great delight) is a fixed construction. The possessive pronoun (seine, ihre, meine) changes according to the person, and the expression is often used with 'daran' and an infinitive construction with 'zu' (to).

The expression 'seine helle Wonne haben' (to take great delight) describes not only great joy, but often has a slightly negative or malicious undertone. Someone is happy about something that may be unpleasant for others.

happiness / luck
'das Glück' and 'die Wonne' can both describe a very positive feeling. 'das Glück' is the normal, broad word for happiness and contentment. It fits many everyday situations and also major feelings about life. 'die Wonne' means an especially strong, pleasant feeling, often connected with pleasure or well-being. It sounds more vivid and less everyday. Learners may confuse the words because both express joy. In most normal sentences, 'Glück' is more natural; 'Wonne' fits when you want to emphasize very intense pleasure.

After the hike, the warm bath was pure bliss.
