I’m afraid not. You can see the music fountain shows from April to October coz the temperature of winter here gets lower so that the water can be frozen. However you can see the lighting sculptures instead.

I don't know

It is very easy to come to Dadaepo. There is Metro subway station no1 which is Dadaepo beach st. Please take subway no.1 any where in Busan and take off at the Dadaepo station. You can find out nature itself and experience different Westend of Busan. Don't forget to take a shot of sunset. Hope to not too late your inquiry.

Open April~September

Not sure how this open air fountain works in the winter. We were there in April. Sorry, cannot provide you with clear answer.
