The Goldenrod Tunnel (Japanese: コガネちかつうろKogane Tunnel), known as the Underground (Japanese: ちかつうろUnderground Path) in Generation II, is a shopping district stretching below Goldenrod City. The shops that are open in the Tunnel depend on the days of the week and, in some cases, the time of day.
Goldenrod Tunnel contains a barber shop, a Bargain Shop that sells valuable items, and an Herb Shop. Each shop has set hours of operation and all three are never open at the same time.
Once a day when the shop is open, the player may have one of the brothers give a Pokémon a haircut. This increases the Pokémon's friendship. In HeartGold and SoulSilver, it also raises the Pokémon's Beauty stat.
The younger of the Haircut brothers is cheaper at $300, but his service is often less satisfactory. However, the younger brother has a chance of occasionally increasing a Pokémon's friendship to a greater degree than the older brother is capable of. The older brother is more reliable but more expensive at $500.
Bargain shop
On Mondaymornings, a man sells a set of valuable items for a discount. Each item can only be purchased once per week. The man can still sell his items on other mornings provided the player has saved in front of him and does not walk away and remove him from the screen. The prices here are approximately 10% cheaper than the items' normal sell prices.
The Goldenrod Department Store's basement opens up onto the Goldenrod Tunnel. Although the basement is accessible from the main store right from the start, the back entrance is initially occupied by Team Rocket and cannot be accessed until later. Petrel hides the Goldenrod Radio Tower Director here while he impersonates him but will give the player the Basement Key upon being defeated. Inside, there are Team Rocket Grunts and Silver to battle and a series of switches to turn ON/OFF in order to navigate through the basement completely.
Some rare items can be found in this section of the Department Store's basement.
During Team Rocket's invasion of the Goldenrod Radio Tower, the player must wear this uniform as a disguise to enter the Radio Tower. They will not battle in this costume nor can they (legitimately) leave Goldenrod City while wearing it.
Photo gallery
The saved photo of a dressed-up Pokémon from the photo booth is displayed in the photo gallery. In addition, photos from up to ten players that have mixed records with will also have their photos displayed here.
A Hiker appears in the photo gallery who runs an Accessory drawing for $100. For each entry, the player has a 6/101 (5.941%) chance of not winning anything at all. Otherwise, the game will try to reward the player with a randomly selected Accessory, with a separate 5/101 (4.950%) chance of also receiving a randomly selected Backdrop.
If the player already has the maximum amount of that particular Accessory, the player will not receive any Accessories for that entry, but may still receive a Backdrop. This means that the effective chance of winning another Accessory gets lower as the pool is exhausted, reaching a minimum of 2.412% for the last Accessory. By contrast, because the game will always select a Backdrop the player has not yet obtained, the chance of receiving another Backdrop remains constant until all of them have been obtained.
On average, it takes about 300 entries to get all of the possible Accessories and Backdrops. Once they have all been obtained, the Hiker will compliment the player on their collection, and no longer offer the player the option to enter the raffle.
The reward pool consists of the following 39 Accessories and 14 Backdrops.
Trainers with a telephone symbol by their names will give their Pokégear number to the player, and may call or be called for a rematch with higher-level Pokémon.

The Underground Path appeared in A Goldenrod Opportunity, where Ash and his friends explored it along with Whitney. She took them through the shopping plaza as an attempted shortcut to the Goldenrod Galleria, but got them lost several times along the way.
In the anime, the Underground Path is portrayed as much larger than it is in the games, but staples from them still appear, including both Haircut brothers.
The Underground Path appeared in Don't Accuse Me. The shopkeepers there framed Red and his Pokémon for being bad, but after Clefairy defeated their Feraligatr, they started to respect him and built an underground area in a department store, which ended up being accidentally destroyed by Clefairy.
