Although Snowpoint City is not home to much, a noticeable landmark in the area is Snowpoint Temple, which can only be accessed after the player has entered the Hall of Fame. The temple contains five floors, with odd bits of slippery ice. At the very bottom of the temple lies a dormant Regigigas. To awaken this Legendary Pokémon, the player must bring all three of the Legendary titans along with them, which are all only available normally in the Generation III games. Through an event Regigigas, the Legendary titans can also be obtained in Platinum and will activate the in-game Regigigas.
Snowpoint's north-easternmost house is home to the place where trendy phrases are obtained. Every day, players can go to the farthest house in the northeast and receive a new trendy phrase. A trendy phrase is an additional phrase which can be used in the easy chat system. It appears in the "Tough Words" category. There are thirty-two different possibilities, all obtainable from an elderly man in the northeasternmost house in the city. Only one may be obtained daily, and receiving a new trendy phrase will not alter any game mechanics. They typically refer to science, business and the arts.
In Pokémon Platinum, a Move Tutor may also be found here.
In the north-westernmost house, a girl named Mindy will trade a Haunter holding an Everstone (which prevents it from evolving into Gengar) for a Medicham. The Haunter is nicknamed "Gaspar" and the OT is "Mindy". The Haunter's ID number is 19248.
On January 10, 2008, Junichi Masuda posted a blog entry urging players to play their Diamond or Pearl on January 12. On that day, the same day as Masuda's birthday, a weather effect called diamond dust occurred in Snowpoint City, replacing the usual snow. It resembles glitter in the air. It is purely aesthetic, since it only occurs within the city where no battles are possible.
The Snowpoint Gym is the official Gym of Snowpoint City. It is based on Ice-typePokémon. The Gym Leader is Candice. Trainers who defeat her receive the Icicle Badge. The Snowpoint City Gym is a Gym consisting of a three-tier ice rink with slides connecting the various tiers and snowballs blocking progress through the Gym. To reach the Gym Leader, Trainers have to slide around the Gym and destroy the balls of snow blocking the way. For defeating Candice, Trainers receive the Icicle Badge, TM72 (Avalanche), and the ability to use Rock Climb outside of battle.
In the anime, Snowpoint City is the hometown of Dawn's rivalZoey. According to Nurse Joy, it is Sinnoh's northernmost city. It has a Pokémon academy that offers classes for both kids and adults wishing to learn more about Pokémon. The city was first mentioned in Our Cup Runneth Over!, when Ash was informed that someone had contacted him from there. It was later revealed that May had placed a call to him from there; after coming to Sinnoh to compete in the Wallace Cup, she decided to stop by Snowpoint City first to evolve her Eevee into Glaceon in front of an Ice Rock that was located near the city.
After this battle, in Pillars of Friendship!, it was discovered that Pokémon HunterJ had broken into Snowpoint Temple in an attempt to steal the Regigigas that lives there. According to legend, long ago, there had been a violent volcanic eruption that had turned the once-beautiful Snowpoint Forest into a sea of lava. Out of a bright blue light, Regigigas had appeared with the Legendary titans and the four had stopped the volcanic eruption, saving Snowpoint City. Afterwards, Regigigas had gone into a deep sleep in the Snowpoint Temple, protected by Regirock, Regice, and Registeel, who had transformed into guardian pillars. In the episode, J was defeated but the temple was nearly destroyed in the battle. Brandon left his three titans behind as protectors and promised to rebuild the temple.
Snowpoint City first appeared in A Novel Test!!, where Hareta arrived there and was met by Candice, who decided to put him into a test to see if he was strong enough to face Team Galactic. The test was a Double Battle, with Hareta facing Candice's legendary titans with Luxio and Riolu. While it seemed for a moment that Hareta was about to lose, he was able to make a comeback when Riolu suddenly evolved into Lucario and defeated both of Candice's Pokémon. Impressed by this, Candice then took Hareta to the Snowpoint Temple, where she used the legendary titans to awaken Regigigas. After a battle with Regigigas, Hareta managed to convince it to come with him.
Snowpoint is home to the northernmost point of access in the games — the entrance of Snowpoint Temple is very slightly north of the northernmost point that can be accessed in the Flower Paradise.
Snowpoint City is the first city or town that is connected to another location that does not connect directly to a route; before reaching a route one must pass through Acuity Lakefront first.
Because of the snow, Snowpoint is one of two locations where bicycles cannot be ridden, though the only one in Sinnoh. The other is Pacifidlog Town in Hoenn.
Snowpoint is similar to Mahogany Town in Johto and Icirrus City in Unova. All three have the 7th Gym to their regions which are all Ice type. They are also near a lake (Snowpoint is near Lake Acuity, whereas Mahogany Town is near the Lake of Rage, and Icirrus City has several lakes surrounding the city.) All places are also near a location that has something to do with snow, hail, or ice (Snowpoint is near the Acuity Lakefront, where it's always snowing; Mahogany Town is near the Ice Path; Icirrus City experiences snowfalls in the winter time.)
The traversable area of Snowpoint City is shaped like a snowflake when viewed from above.
Snowpoint's snowflake shape, however, has eight points. Because of the properties of water molecules, real snowflakes only ever have 6 points or sides.
