Puzzletober 2024: Hike

 Swimming across the rivers to visit the middle southern tip of the island was more efficient than retracing my steps. I felt obliged to hike some of the trails left behind, but some of them would have to wait. I especially couldn't attempt the ones deep underwater offshore. I can't swim that far.

Rules: Solve as a Water Walk, except with a path that travels from the leftmost trail to the rightmost trail. Some trails have been marked: if the path goes over a trail, it must follow the full trail.

(Note: there is a slight nonuniqueness that can be fixed by adding 2-cell horizontal trails directly above the submerged ones.)
