Route 205 to Eterna Forest

Having cleared out the Windworks, it is time to leave there and start back on your way to Eterna City.

When you step outside of the Windworks Looker will be there having tailed Team Galactic to that building. He will be somewhat  surprised at the results of you clearing them out and head inside to investigate. After a few moments, he will return and be praising you for your efforts. He declares he shall continue his pursuit of the culprits. He tells you that Team Galactic has a hideout in Eterna City and sets off.

Follow the path back to the bridge going across the river that the pair of Team Galactic Grunts were blocking your way. On the other side of the bridge, you will see a Honey Tree to your left, with a boy looking at it.. He will tell you that by slathering honey on these trees Pokemon will be attracted. Follow the dirt path upwards. You will see another trainer, Camper Jacob, who has a Ponyta, lvl. 14, which will alternate between using Ember and Tackle. He will tell you that there are tough Pokemon in Eterna Forest. To make forward progress, you need to head into the nearby grass to your left, heading upwards a bit. You will see some stairs, take those. On top, you will see an item to the right. It has X Sp. Def in it. There is a Hiker nearby it though, who will be looking around, so he may challenge you. He has Geodudes lvl. 10, lvl. 11, and lvl. 12. As long as you have fighting, water or grass moves it will be no problem to take them out.

After the Hiker, you will see two sets of stairs:
Going down the stairs to the right has you fight Aroma Lady Elizabeth who has a Roselina at lvl. 14. This one will likely use Growth to boost its Sp. Attack then use Mega Drain on you. It will just keep doing so until she wins if you let her. Fire, Psychic or Flying type attacks will floor the Roselina quickly. After her, go up along the right side, you will see another trainer, Picnicker Seina, who has a lvl. 12 Bidoof, who will slowly attack you and a Pachirisu, lvl. 12, which will debuff your attack with Growl then start using Quick Attack until it faints. After her, look up and to the left to see 2 berry plants, a Pecha and an Oran. Further to the left is an item ball, near the water, which has a Heal Ball in it. Immediately that is all one can get in this stretch, so head back to the stairs you went down.

The other set of stairs goes straight up. You will see a trainer pacing in a large square. This is Camper Zachary, who has an Aipom, lvl 14. It will likely open with Astonish, which can cause your Pokemon to flinch, then use Sand-Attack to lower your accuracy. It will alternate between those two attacks. After him, just keep going upwards, across the bridge.

On the far side is a lost Hiker, Nicholas, who challenges you with his lvl. 14 Onix. It will Screech to lower your Defense, then attack. Keep on the aggressive tactic to take it out with minimal trouble. Just continue upwards. You will see an item ball above you to the left and a pacing trainer. The item ball has a Repel inside. The trainer is Battle Girl Kelsey, who has a lvl. 15 Machop. It will use Focus Energy then attack with Karate Chop. Thankfully, Machops are just young ones, so they too, are not too difficult. Keep going upwards, favoring the right side.  You will see another trainer and a house. The trainer is Picnicker Karina who has a lvl. 14 Piplup. It is not too difficult a fight. The house nearby has a boy who tells you about the advantages and disadvantages of Repel and a woman who offers to let you rest which will restore your Pokemon to full health. If you want to grab a Super Potion, head down the two sets of stairs from the house to grab the item ball with one in it.

After that, head upwards, past the house. You will see a forest and a person pacing outside it. He will comment that he did not get any antidotes and Eterna Forerst is full of Poison type Pokemon. This is not thing to do, if you have the money to spare. After that, head into the forest to get ever closer to Eterna City.
