Open Area Base Locations - Palworld
Open base locations make for excellent main base or ranch/breeding base spots. Ideally a good open location will have minimal resources, you want as little stuff as possible obstructing your building. Resources around your base are fine and can be helpful but in Palworld almost everything you need can be farmed from a Quarry which you can make in your base. Most stuff that doesn't come from a Quarry can be farmed from Expeditions. So typically there's no real reason to make your main base at a cluster of resources.
It's strongly advised you separate your Main Base and your Breeding/Ranch base as well. Ranches will handicap your Pals ability to effectively transport materials because they'll focus on Ranch drops and only carry 1 item at a time. This will dramatically slow down all production at your base and there is no real solution aside from putting your Ranches at a different base.
(Early - Mid Game) Southern Base
This spot is a great early game main base location, it is in a wide open area without many natural resources to get in your way. Just north of this location is also a Skill Fruit Tree which you can raid every so often for a chance at getting something good.
(Early - Mid Game) Marsh Island Open Area
Marsh Island is relatively close to the Hill of Beginnings where you start the game, so this makes a good initial base location. There are no note worthy resources at this location except Stone and Wood
(Early-Mid Game) Ice Wind Isle Open Area Base
It's a big open area where you're free to build whatever you want. There are some Ore nodes nearby if you wanted to encircle them too but I don't recommend it. An area like this is designed to have as little clutter as possible and Ore nodes would just be clutter. One upside of this location is it's close to the ice mountain and japanese island.
(Mid-Game) Saruman's Tower
One of my favorite base locations on this list is regarded as 'Saruman's Tower' in the community. There is a huge pillar here with 4 chests that sit ontop of it, you can make a Palbox right in the middle of this pillar and have plenty of room to build. You can find numerous egg spawns around the base of the tower as well as a dungeon entrance. With the 1.0 release there's also an egg that spawns up at the top of the tower too.
(Mid to Late Game) Feybreak Eastern Base
Feybreak has a bunch of locations for you to make a base, this is probably my favorite of them though. The area is big enough for you to just barely fit a Palbox's circle on the flat part. You can also find a chest very close to where you put down your Palbox, it's just a tad bit north inside this flat dirt area.
(Mid to Late Game) Ocean Bases
Starting with the 1.0 launch of Palworld, we're now able to craft on the open ocean! In my opinion this is a great option for people who want to put multiple bases close to each other and/or people with worse computers. As you can see in the picture above, I have one base that's far away from land and the other bases. This is my main base and I didn't want to hit a limit where there's so much stuff that I start dropping the FPS in the surrounding area. So I made my base in a spot where there's nothing around which gives me more leeway.
The other two bases that are close to each other are my Ranch/Breeding bases. One has all my Ranch Pals and the other has whatever I am breeding at the time. These bases are what I kept from Mid game to the end of the game.
