The second optional side area you can explore upon arriving in Dendemille Town, Route 16 is an area you can skip completely if you're in a hurry. It connects Dendemille Town with Lumiose City in the center of Kalos, a diversion you don't really need if one of your Pokémon can use Fly. It's still a good idea to check Route 16 out, as there are plenty of good items to collect and Pokémon to catch between the two settlements.

Head south from Route 15 and the Dendemill Town entrance. You'll need Strength to push the boulder into place and access the Route. To your left is a set of ruins. Beyond the tall grass inside them are the stairs leading to the southern half of the Lost Hotel, which we explored in the previous section of the walkthrough. Go up the stairs to the ruined second floor and check out the top-left floor tile for a hidden Max Revive.

There's a woman standing on a cliff to the south. Approach her and you'll get into a Sky Trainer battle.

Sky Trainer Clara
  • Emolga, level 38
  • Swellow, level 40
Reward: 4,000 P

Emolga remains a terrible nuisance and a great threat if you're using an actual Flying-type for the battle. Try to wipe it out quickly with a Rock-type move, if possible. Swellow can be rough, but it doesn't have much HP and is more straightforward than the paralysis-happy Emolga.

Head west to find a big patch of grass. Go through it to find a Cuttable tree. North is another patch of grass, and you'll find a small clearing in the northeast corner where a Rare Candy is waiting. Head back to the main path. Wait for a second and a skater will zip by. Another will roll past if you wait a few more seconds after the first battle.

Roller Skater Jet
  • Delcatty, level 37
  • Swanna, level 39
Reward: 1,248 P

Roller Skater Olle
  • Manectric, level 40
Reward: 1,280 P

Follow the path west until it's covered in leaves. Go through the grass on the north side to find a small clearing. You can challenge a Sky Trainer here by standing in front of a sign.

Sky Trainer Gavin
  • Chimecho, level 37
  • Vibrava, level 37
  • Talonflame, 39
Reward: 3,900 P

Return to the main path and follow it between the tall grass. Beyond a curve to the south you'll find a hidden trainer.

Pokémon Ranger Lee
  • Crawdaunt, level 39
  • Sandslash, level 39
Reward: 3,120 P

Head south. Hiding in the tall grass to your left is another trainer. East of her is a Lum Berry tree.

Hex Maniac Osanna
  • Pumpkaboo, level 40
Reward: 1,280 P

South of Osanna and the Lum Berry tree is another big grass patch. Go through it to the east to find a Max Potion. Return to the main path and follow it to find a lump of leaves, hidden under which is a Big Mushroom. Further west down the path you'll find two more lumps of leaves, and under the left lump is a trainer.

Pokémon Ranger Bjorn
  • Sliggo, level 41
Reward: 3,280 P

Head down the stairs to the north. There are two trainers waiting.

Mysterious Sisters Achlys & Eos
  • Alakazam, level 40
  • Gardevoir, level 40
Reward: 2,560 P

This pair can be quite painful if you don't get the initiative. Put a fast Pokémon with a strong physical attack up first to out-speed Alakazam and bring it down. Dark-type is, of course, preferred. Gardevoir is much less dangerous on its own.

Push the boulder beyond the Mysterious Sisters into place with Strength. Past here the path splits. To the north you'll find trees to Cut and water to Surf, but nothing much else just yet since you can't climb the nearby waterfall. To the west is a trainer on patrol.

Fairy Tale Girl Alice
  • Klefki, level 37
  • Mawile, level 39
Reward: 1,248 P

Head south, down the stairs, and through the next flower field. Push the boulder beyond into place with Strength. Past here is a Fist Plate and, in the rock beside it, a Rare Candy.

Head back to the main path. On the side of the water is a shack. One of the Fishermen inside will give you the Super Rod, the best Rod in the game, and the other will give you Dive Balls if you manage to defeat his record of seven consecutive Pokémon catches via a fishing rod.

There are three trainers on the boardwalks beside the shack. You can engage or ignore them, as they're too busy fishing to fight you automatically. Beside the guy in the middle, hidden on his left side, is a Repel. Check the west side of the strip of land beyond the boardwalks to find a Dive Ball.

Fisherman Wade
  • Poliwhirl, level 37
  • Poliwhirl, level 39
Reward: 2,184 P

Fisherman Seward
  • Whiscash, level 40
Reward: 2,240 P

Whiscash loves to use Rest, and can Snore while asleep to do damage. A Grass-type move is your best bet to win this fight in a hurry. Don't bother with status effects other than putting Whiscash to sleep, as Rest will supersede any other status.

Fisherman Finn
  • Basculin, level 38
  • Basculin, level 38
Reward: 2,128 P

That's all for Route 16 until you've gotten through the game. West of the shack where you got the Super Rod is the exit to Lumiose City.

Return Trip
  • Come to this route between 8 and 9 PM after upgrading the Mega Ring. Look for the small area on the Dendemille Town side of Route 16 where two skaters are circling a rock formation. You'll find either Manectricite (Pokémon X) or Houndoominite (Pokémon Y).
  • On the Dendemille Town side of Route 16 is a waterfall you can climb with Waterfall. Follow the watery path east and north to return to Route 15. TM 97 Dark Pulse is up here.
