No, Amity Square is the only place in Pokemon Diamond, Pearl, and Platinum where you can stroll with Pokemon.
Go south of Eterna City then into Mt. Coronet. After that keep going east until you reach Hearthome City.
It is just below Hearthome city. Keep going down until you see an enormous house.
Well, if you have finished the game, you can get there by going left from hearthome city.
find him by going to the big mansion near hearthome there he will be on the right in the mansion talk to him! xd hope this helps
From what i know you can only catch eevee in the Pokemon mansion on the route you take when you are going from Hearthome. Take the back door to the garden.
next to hearthome city on the left[just keep going left until you are out of the city, in a route and finally in cornet]
You must do Eterna City and then you ride down the cycling lane and stop at the ramp and then turn right! keep going and you will see Lucas then enter Mt.Coronet! Find your way through Mt.Coronet and then you are in A random place then keep going right and you will find Hearthome City
Go to Hearthome City and then go to the house to the right of the Pokemon center. Talk to Bebe, the lady in the house, and she will give you an Eevee. You can also get it by going to the old masion in hearthome city!!! talk to balot and he will get it for you!! but it will take a long time!!!!!
stroll
yes check in the route going down from hearthome city check the trainer next to the small pond close to the top of the route
The Pokemon is JOLTEON you can get one by using a thunder stone on an EEVEE you can get an EEVEE by going in the house next to the Pokemon centre in hearthome city, -i think- but just check every city and the houses next to the Pokemon centre's, hope this helps!
