you can only get to some sections by going through one of the healed fertile grounds. Select one of the other grounds to fix and go back through the first fertile grounds to the next one. Pull up the map every now and then if needed.
Hope that helps some
Thanks I solved my problem the next time I went thru the jump and crab poles area the compass led me to the vale which is left of where it directed me to before.Got there killed the boss and healed the area.
