That's how it looked like for me when I first found the biome, on an old seed. But I've seen really fragmented coasts and even standalone islands which lacked access to other biomes entirely.

It might be worth not disembarking immediately when finding the biome, and instead choosing to circle around the landmass to get a better idea what you're dealing with. I progressed on that map from west to east, from south to north. I guess I got lucky finding a mist-free vale after the initial scramble for broken shores and some deaths.

There also exists mistlands regions with mountains in the middle or alongside of them, might make for a good vantage point or even forward base. And decent scenery.
