For Let's Go Eevee: What place spawns the most Pokemon in the shortest time possible?

Question

I found out that there is a specific cave that spawns the best Pokémon, but I don't know where or if that is true. I want to find a place so I can chain and get shinies faster.

Answer 1

In Let's Go Pikachu and Let's Go Eevee, the best places for shiny hunting are:

• Viridian Forest
• Mt. Moon
• Route 6

These locations boast wide-open spaces with frequent spawns, making them ideal for shiny hunting. While areas like Rock Tunnel and Cerulean Cave also have open spaces, they don't spawn Pokémon as frequently as the three listed above. Any of these spots will give you plenty of encounters to work with.
