I have noticed during my play-throughs that I've been completely avoiding this area of the forest, and if I get a mission that takes me there, I will actually not accept that mission at all (lol).
Getting there without the second portal appearing at the fallen train bridge is a tough task on its own, and than there are more enemies to deal there, so it never felt worth it to go there, unless I was just out to explore for exploration' sake. By the time of the second portal at the train bridge appearing, I'm ignoring the area entirely and using the portals shortcut through the peninsula, train bridge and than straight to pechorsk outskirts and skipping that area entirely.
So yeah I thought it would be cool if there was a special incentive to go there, especially at the coast of the cool, because it seemed like a cool place to wind up in that I feel like you don't really go to unless you're making a point of wasting time instead of calculating your moves to avoid getting caught in the next tide.
