Walking(산책하기 or 산책)

(저는) 가끔 혼자 있는 것을 좋아해요. (저는) 오늘밤 강가에 있는 길에(or 길로 or 길을) 산책하러 갔어요. (그 길은) 제 집에서집에 가까워요. 공중이바람이 고요하고(or 잔잔하고) 따스해요.
(Sometimes I like being alone. Tonight I went for a walk on the path by the river. It's near my house. The air is still and warm)

Generally, the subject "나는 or 저는" can be omitted in a casual writing, such as a personal diary or essay. But I think it would be better not to omit any element of the clause when you writing because you are not familiar to using them yet.

Please look at the follwing phrases. And then, compare the difference of their meanings.

You should consider the adverbial case particles, -(으)로, -에, and the objective case particle, -을(를).

to go for a walk on the path by the river

to go for a walk to the path by the river

산책하러 for a walk

강가에 있는 길-로/길-에/길-을 가다. to go for a walk to/on the path by the river

The adjective 고요하다 means to be silent or still. In this case, however, the word 'still' is usually translated into the adjective 잔잔하다.

Silent night, Holy night

고요한 밤, 거룩한 밤

All is calm, all is bright

어둠에 묻힌 밤

Walking
