The hard mode exploring would be starting from somepoint were the wizard is, then you explore the entire region as a pokemon trying to find hidden grottos where there are rare items to find. You can't be healed in Pokemon centers but if you find a breeder or ranger you can ask them for a berry. Basically transform into a pokemon to access were humans can't go in, like in that section from Rocket HQ in LGPE
