Route 763

Route 763 is one of the many ocean routes. It connects to Route 762 and Route 764 to Breezyshore Beach. You'll need a Pokemon who knows surf though. Without it, you won't be able to get there, ha ha! Now the weather is mostly clear but there are times where it will rain. No problem though. A little rain never hurts anyone. You can find most of the usual water Pokemon like Chinchou, Staryu, Starmie, Caravahn, Magikarp. Remember, Magikarp may seem like a weak Pokemon but with some training, you can get one of the most powerful Pokemon there is.

Good luck, Pokemon Trainers.
