well you 1.go on the bridge when you first headed straight for eterna forest and head left (there will be alot of water type so either bring repels or thunder type)then when you can get onto land go up and there you are
another way you can go right on the bridge and get thunderbolt and electrizer(i think) when you get you go up you can also go down and when you where at the honey farm there is a spot behind it where you can get some things like leaf stone and some other things.
