I bet you live much closer than 1500km to a river or lake. Many of those bodies of water have public trails or sometimes even little sandy beaches. You won’t find shells but there’s plenty of other cool stuff to search for like the perfect skipping stone or walking stick, or a rock with a really cool color pattern, or mushrooms, etc. There’s something inexplicably restorative about spending time in nature near water.
