Reversal Mountain - Black 2
The path into Reversal Mountain gives you little choice, at first: Head north. Shortly after entering you'll see a Max Repel on the ground to the west. Grab it, then head through the next cave you come to. On the other side is Bianca, still exploring the place, and she needs help fending off the wild Pokémon. It's double battles from here on in - and, as always with partners, Bianca will heal your team after each battle. Pretty sweet.
Start by going south. You'll find a trainer who wants to get into a Rotation Battle... which, naturally, doesn't include Bianca. Doi.
Black Belt Corey
The path splits ahead. Go up the stairs on your right, then up the northern path to find a Nugget. Head back down the stairs and continue south to run into a pair of trainers. Just before you engage them in battle, check the stalagmite in the path for a Green Shard.
Backpacker Kiyo and Hiker Markus
Slightly south and to the east of the trainers you'll find a Hyper Potion, and further down the path you'll find a hidden Blue Shard. Backtrack to the path and go south to the wall, noting the slight bit of shadow against the south wall. This is a door you can go through, leading to two more doors. The east door will take you out near the Strange House, and the south will give you access to two items you couldn't reach before, namely an Escape Rope and a Smoke Ball.
Head back to the hall and go east. You'll soon run into a trainer.
Pokémon Ranger Eliza
A short ways east of this trainer you'll find a Doctor near a set of stairs leading into the basement. Bianca proclaims that this is the place. Start by offing the Doctor's Pokémon. (Though with Bianca around you don't much need his services.)
Doctor Derek
Rather than heeding Bianca's advice, continue east for now. Along the path is a northern branch leading to TM69 Rock Polish. You're also likely to run into a patrolling trainer who wants a Triple Battle.
Battle Girl Chan
Go all the way east past the trainer to find a stalagmite with a Star Piece. Turn back once you have it and go up the first northern passage you find. It will lead you to a Revive.
Now you can backtrack to the large staircase. At the bottom, Bianca will postulate that this small area is the resting place of the Pokémon Heatran, a fiery beast with a great temper - one that may be lured here if you bring a specific item. Say, perhaps, the Magma Stone one of the trainers you trounced earlier kept mentioning? Keep that bit of info in the back of your mind, as you'll be able to catch Heatran here some day if you bring a Magma Stone.
This is a dead end, so backtrack all the way to the first split in the path, where you originally met Bianca. Head east from the split to get into a battle with a pair of rugged mountain trainers.
Hiker Jared and Backpacker Kumiko
To the south of Jared is a PP Up. Further east along this path is another pair of trainers.
Ace Trainer Cora and Ace Trainer Ray
Go south from the Ace Trainers. You'll find a western path that leads to a dead end - and a hidden Calcium. Sniff it out with your Dowsing Machine, then backtrack to the trainers and carry on east. You'll soon find a split in the path, and at it a Scientist who will give you TM54 False Swipe if you show him the complete Habitat List for this area. Further east is the exit from Reversal Mountain, but you're not done yet. Go south.
The path will move up two levels at some stairs. Check the stalagmite at the top of these stairs for an Elixir. Enter the next door you see to find more stairs, and beside them a stalagmite containing a Water Gem. At the bottom of the stairs you'll face a trainer guarding a Toxic Orb.
Pokémon Ranger Lewis
That's all there is. Return to the Scientist and take a right. You'll find the exit to the cave - and though Bianca makes it sound as though there might be more to Reversal Mountain, there isn't. (For the moment.) Say your goodbyes and leave. You're now in Undella Town! That was sudden.
Doctor Derek
Head down the stairs along the left path before you investigate the north. There's a Flame Orb down here, and if you follow the path north you'll hit a trainer before long. Hidden a rock to the northwest of the trainer is a Fire Gem.

Reversal Mountain - White 2
When you first enter Reversal Mountain you'll be forced north. Check to your left as you walk to find a Max Repel, then head through the door in the north. Bianca is on the other side, and she will join you in a search around Reversal Mountain. She will participate in Multi Battles with you, and heal your Pokémon after each battle. Very handy. If you want to fight trainers individually, make sure you approach them from the side.
Head east to find a dead end with a Hyper Potion, then trek south. The path will split to the east and south, and you'll see two trainers to the south. Both paths join up, so fight the southern trainers quick, then take the eastern path to fight a third, who will challenge you to a Triple Battle.

- Gurdurr, level 37
- Riolu, level 37
North of Chan you'll find a hidden Elixir at a dead end. South of Chan and to the right you'll find another dead end with TM69 Rock Polish. South of the two trainers you'll find the path onward. As the path sweeps right you'll see a trainer roaming to the right. Before you challenge him, pop your head into the tunnel at the bend - you can see its shadow on the ground - and you'll find two exits inside. One leads to nothing, the other to an Escape Rope and a Smoke Ball.
Pokémon Ranger Lewis
- Watchog, level 38
- Camerupt, level 38
Head east from Lewis. You'll find a Doctor near a set of stairs leading into the basement. Bianca proclaims that this is the place. Start by offing the Doctor's Pokémon. (Though with Bianca around you don't much need his services.)
Doctor Derek
- Swoobat, level 38
At the bottom of the stairs near Derek you'll find an empty chamber. Bianca believes that this is the room of Heatran, a Legendary Pokémon that likes hot places. It's not here now, but you can bring an item here much later in the game to make it appear.
Head back upstairs and carry on east. The path will split again, to the east and the north. Going eastbound will bring you to a dead end with a hidden Red Shard, tucked into a rock. Both of the northbound paths will bring you to trainers. The path on the left will take you to stairs, a PP Up, and a hidden Star Piece, while the path on the right will take you to a Revive. The paths will join up again in the north.

- Grumpig, level 39 (Cora)
- Drifblim, level 39 (Cora)
- Vibrava, level 39 (Ray)
- Camerupt, level 39 (Ray)
Head east of the trainers. You'll find an intersection with a Scientist who will give you TM54 False Swipe if you show him the complete Habitat List for this area. Just south of him is a Nugget. Carry on east of the Scientist and you'll find the exit to Undella Town, your next destination, and Bianca will part ways with you here. Onward!
