We went to Awajishima recently. It is an island between Osaka/Kobe and Shikoku; famous for onions and daffodils amongst other things. It wasn’t really onion season but daffodils were in full bloom and the views of steep sided hills full of nodding daffodils and the sea were breathtaking.
Breathtaking is an adjective you can use when describing something that is beautiful or amazing and view is a common word that goes with it. For example, Awajishima has breathtaking views.
