Walkthrough
Just north of the Meetup Spot is the Wild Area found in The Galar Region, which are many different fields that contain a variety of different Pokemon. The first section of the Wild Area includes Rolling Fields, Dappled Grove, West Lake Awewell, Watchtower Ruins, Axew's Eye, South Lake Miloch, Giant's Seat, North Lake Miloch, and East Lake Awewell. The Weather also rotates within each given section of the Wild Area, allowing different Pokemon to appear depending on the weather. Also found with the Wild Area are Pokemon Dens that could contain Max Raid Battles, as well as a number of Watt Traders that will sell you a variety of items in exchange for Watts.
The goal at this point in the game is to make it through the many sections Wild Area on your way to meeting Hop in Motostoke. However, take some time to participate in the lower-leveled Max Raid Battles while you do so you can help improve your Pokemon Team. Just watch out for the Strong Pokemon that walk the Wild Area, as they will be far to strong to battle/capture. (Do note that all Wild Pokemon will be at Level 60 after the completion of the Main Story.)
