Ilex Forest (Japanese: ウバメのもり Ubame Forest) is a dense forest located in southern Johto, directly west of Azalea Town. The forest's trees are so close together that all light is blocked out, and the forest seems to be in a perpetual night.
The only important feature in the forest is a shrine to Celebi.

oute 34 is a final trek after the long way through Ilex Forest. Unlike the route before, this route has a lot of tall grass and many Trainers. Route 34 is also where the first ever Day Care in which Pokémon can breed is located.The route is essentially straightforward after exiting Ilex Forest. There is a path where no long grass grows, however, it is filled with many trainers. This road can be difficult if a trainer doesn't go back to Azalea Town to heal their Pokémon after facing his/her rival in the forest. The Day Care, run by an old couple, is one of the most prominent things located here. Located merely steps away from the famous Goldenrod City, this center allows for compatible male and female Pokémon to breed and produce an egg. It also allows trainers to leave up to two of their Pokémon to level up, costing, like the Pokémon Daycare on Route 5, 100 plus an additional 100 per level up for each Pokémon. Coincidentally, like the location of the Day Care in Kanto, this route is also the fifth route in Johto.
