I took a stroll through the blight 164 test and found if they steer clear of the maple trees to the right and stay on the left side of the road, they can avoid the treants.

If they drop off the cliff after the wall (near the "cave below the water" for AROP) and run along the beach they can get to breath of fire safely running from Morning Light. (There are twisted automations on the exit of the new city, so running through the city would be a bad thing)

Glad to know that was thought about when they revamped the area.
