1. When you get to Island One go into the place that looks like a gym take to the man in front of the machine.(Celio) He will ask you to retrieve two gems(Sapphire and the Ruby). You need to realize that you must have at least 60 different types of Pokemon before starting on your way. The next thing you do is go see Profs. Oak in his lab and have him check your Pokedex. Go back to Island One make sure you have HM3(Surf) and HM6(Rock Smash) to get off the island. 2. Use Surf and head up towards land this is the part were Rock Smash comes in handy, there are a lot of trainers so be ready to fight. The Pokemon in this area are in the thirties and the first trainer has two Meowths level 35, a Pikachu level 35, and a Clefairy level 35. Continue up the island you will encounter 3 more trainers and a couple. If you need health enter into the Ember Spa follow the trail right and enter into the center of the pool your Pokemon health will fully be restored. Continue up the island until you hit the water front.
3. For this part though I would use some form of a repel: Repel 100 steps, Super Repel 200 steps, and the Max Repel 500 steps. Use surf but beware there are to trainers in the water and one on land continued going up till you come to another island go up. When you enter go to your right there will be two Team Rocket Grunts and a hole behind the one on the right you must face both separately then enter the the cave.
