Casseroya Lake has three watchtowers. Casseroya Watchtower No. 1 is located south of the lake, adjacent to the river that borders West Province (Area Two). Casseroya Watchtower No. 2 is located northeast of Casseroya Watchtower No. 1, closer to the border of the lake. Casseroya Watchtower No. 3 is located on a cliffside to the northeast, right by Glaseado Mountain between Casseroya Falls and Glaseado's Grasp. A Chest Form Gimmighoul can be found and battled at each watchtower.
Socarrat Trail is a subregion of Casseroya Lake that encompasses most of the northern shore of the lake. It features colorful foliage and is home to the Groundblight Shrine.

After acquiring the corresponding Treat from Snacksworth, certain Legendary Pokémon will spawn in this area as a static encounter. If defeated, they can be battled again after the game has been rebooted, provided that over one hour has passed in Nintendo Switch's internal clock since their defeat. They are coded to never be Shiny.
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here. Probability weight indicates the likelihood that a Pokémon will spawn at a certain point in this location relative to others that can spawn there. A higher probability weight generally indicates that a Pokémon is more likely to spawn. Pokémon with the highest or lowest level requirements may not spawn in every possible location within this area. A bolded level range replaces the Pokémon's non-bolded level range after the player has completed The Way Home.
