This isn't compatible with clickable worlds mod, just thought I'd let anyone downloading it know to save them some time if the interactions don't show up. Maybe can add it to the conflicts list. Thank you so much for making this, I've wanted my sims to swim in Brindelton Bay for so long!

Can't get the mod to work unfortunately, I've followed all the steps and it doesn't show the "swim here" button :(

Colette Lee · July 20, 2026

I am a water sign and you have no idea how much I was missing this aspect in my game

ot · July 9, 2026

hey! looking over the instructions and I'm a bit confused. I assume the swimmable worlds, seasons master fix, and sunblind world files are in the option with all three? as in since I already have the sunblind mod, but never used the seasons master fix and would like to now, I don't have to download the mod separately? and when I download the all three version I don't have to worry about sunblind's world files?

ot · July 9, 2026

nvm chile, I saw it on a previous post!

Aya · April 27, 2026

Hello! I did everything as in the guide but nothing changed in my game. I noticed the same thing happened when i tried to resize lots with sims4studio, even though i modified the world file nothing changed in game. Any idea what I am doing wrong? Do i need to start a new save for the change to update?

AbstractedGrl · April 18, 2026

Hey, thanks for creating this mod. Just something that I started noticing after installing it. I did everything as you said, and I didn't encounter any problem, just that when I try playing in 2x or 3x speed, the game just stop responding, like i can't select anything. I don't know if it is interfiring with another mod that I dont know about, but just letting you know. Thanks again for this mod. Is very useful.

Kyle Salinas-Simmons · April 6, 2026

hi, is there a tutorial on how to add this to the game on iOS ?

N
Naja Højholt · March 28, 2026

Hi just here to report that this mod is not working after the patch (: I love the whole swimmable worlds series and I almost can't play without them :o <3 Thank your for all your hard work, it's much appreciated!

N
NerdyDoll · March 30, 2026

Hi, the mod is compatible with the update - in fact, it rarely needs an update. That being said when there's a game update or the game is repaired, the world files get ovewritten with the original so it may be possible you have to reinstall the mod. However if it still doesn't work after reinstalling let me know and I'll try to look more into it.

K
Kate · March 23, 2026

As a person who is obsessed with swimming, your mods are everything I've been waiting for in the sims <3 Just a small report - after the recent update, the phase I mode has stopped working for me, all other swimmable mods still do thankfully. Thank you again!

S
Sayuri Ayame · March 12, 2026

I love your mods! And I dont want to sound like I am complaining I am certainly not. I am truthfully grateful someone finally made this possible. as well as many others I am sure. I am in heaven with this mod <3 But I use Blowtorch, to empty my worlds because I play a ancient safe file. and sadly your files and the Blowtorch files lay on top of each other. So now I wonder if there is any way to combine this. I am sorry if I bother you with this too, its not my intention.

Liv9987765 · March 9, 2026

I really can't get the mod to work, anyone knows what I could be doing wrong?

DesireePlays · March 6, 2026

is there anyway you can add Brindleton Bay?

heidi (Team de luniversims.fr) · February 12, 2026

Thank you for Sunblinb and the seasons, that's so kind, thank you from the bottom of my heart.🌸​

BhadHabitz · January 25, 2026

WOW! thank you so much :))))))))))))))))))) i've always wanted to be able to swim in Brindleton Bay. You made my dreams come true :')

M
Morgan · January 16, 2026

As someone who lives and dies by Milk Thistle you have no idea how sad I am to be this torn. Do I swim or have good lighting? This is an unfair and evil decision to force me to make (this is teasing because this mod is awesome)

S
Simgraphy · December 9, 2025

Will the waters of The Crumbling Isle neighborhood in Windenburg will also be made swimmable ?? That would be so cool

S
Simday1 · December 5, 2025

Is there any chance for the other areas in San Sequoia to be swimmable? Thank You

a
alexis desiree · December 1, 2025

Do you think you'll make one for Selvadorada? There's one area in that has water that I would like my sims to be able to swim in.

L
Lydia · November 17, 2025

Hi! Thank you so much for this! I've been waiting for a mod like this forever! Could you please make it compatible with Twinkle Toes by softerhaze?

J
John Chau · November 11, 2025

Think you might make a version of Swimmable Worlds that is compatible with both lotharihoe’s Purple Skies (https://lotharihoe.itch.io/purple-skies) and Lunar_Britney’s Seasons Master Fix (https://modthesims.info/d/692031/seasons-master-fix-wip.html)?

J
Jacquie Fanning · November 1, 2025

Can't believe EA doesn't do the same in making these places swimmabe, but thank you for making this mod! I took me a couple of tries to get it to work, but that is because I didn't follow you directions (next time Jacquie, read the instructions, lol!) It works so wonderfully in my game and I can't wait to get the other phases of this mod. Thanks for all of the hard work you put into it!

Itsmonicarose · October 28, 2025

Hi 🫶🏼 first of all thank you so much for creating this mod for us! I am really excited about and tried installing it in my game. I followed the instructions, made sure I also replaced the files in the delta folder etc and installed the mod but, like mentioned on the latest comment, I am unable to swim. I get the “float here” option, the option to select vehicles, but nothing happens and when click on float here the sim does the animation where she can’t move there. There is no swim here option. I am only able to place the vehicles in the water in worlds where swimming comes with the game like sunali etc. any tips? 🩷

m
mercifuldayzz · October 21, 2025

hey I downloaded the files into the right folder but everytime when I click on the place where they can swim they act as if they can't move there and the bonus mod when i select a vehicle object, doesn't do nothing. No vehicles appear so I am a bit confused because I downloaded all the phases you have

I
Itsmonicarose · October 28, 2025

I’m having the same exact problem😭😭

A
Astrid · October 19, 2025

Just tested it out and it works great! I can't thank you enough for this mod. I was dying to make a merman terrorizing Brindleton Bay and this had allowed me to make my little scenario come true. Thanks again!

G
G N · October 18, 2025

Hi! Do you need to follow the instructions each time you've done an update to your game?

N
NerdyDoll · October 18, 2025

If it resets the world files, yes. How to know if it did? The mod won't work :( but great news is, it's enough to replace the world files in the Delta folders, so once you installed the mod, updating it will take max 1 minute when needed.

K
Karen O`Brien · October 17, 2025

Hey can someone point me towards the download instructions I cant seem to find it

N
NerdyDoll · October 18, 2025

It's inside the installation folder.

H
Howa · October 11, 2025

Hi! I followed the download instructions but there are no interactions on the water in brindleton bay in either of the locations, could the latest patch be the culprit?? Thanks!

N
NerdyDoll · October 11, 2025

No, mod is compatible and highly unlikely to break from a patch update (though it may need to be reinstalled with patches). Please check if you've added the world files to the Delta folders.

K
Kerry Kelly · October 6, 2025

I downloaded all of these...only tried using the Brindleton Bay ones so far...and it seems neither of these worked? I deleted (saved the original for back up) and put in your files and followed the directions but for some reason yet the water is not swimmable here.

N
NerdyDoll · October 8, 2025

Please check if you have replaced the world files in the Delta folders.

P
Polina Kuzmina · October 6, 2025

Hi =) I haven't checked if it's been fixed but just in case -- in Brindleton Bay (the beach place) there is a lot and next to it there is a fishing pond -- for some reason the water in the pond got deleted

N
NerdyDoll · October 8, 2025

Hi! I'll check it out, thank you for letting me know!

S
Solelysunnys crib · October 5, 2025

How do I download this? Are these files supposed to go in your mods folder, or in a completely different folder?

N
NerdyDoll · October 8, 2025

Once you download a desired world there will be a set of instructions to follow.

L
Lauren Williamson · October 5, 2025

Hi! I'm so excited to use this mod! I've tried to install it multiple times on my Mac but I'm unable to find the delta files to override - does anyone have any tips?

N
NerdyDoll · October 8, 2025

Hi! If you open the App (EA App, Steam) you use to launch the game, there will be an option to open the game folders. There are pictures in the installation instructions.

milk thistle next???

SulSul · September 30, 2025

This is the mod i've been waiting for so i'm super stoked about it!! However it's only working in Brindleton Bay for me though.. is this a known issue? I followed the instructions so I don't know why it didn't work

D
DreamiNae · September 28, 2025

this C:\Program Files\EA Games\The Sims 4\EP04\Worlds\Areas does not show up on my Windows laptop? Any suggestions

N
NerdyDoll · September 29, 2025

If you have EP04 installed, it must be there however it may be in a different place. If you open the EA App, you can find the needed folders. For better info, please check the installation doc.

savannah · September 25, 2025

OMGGG YOU ADDED SUNBLIND THANK YOU THANK YOU 🤍 will part two be compatible with sunblind as well eventually? :)

N
NerdyDoll · September 29, 2025

Yes, part two will be compatible soon as well!

b
bobobohouy · September 25, 2025

hello do i download all the files or only one of them

N
NerdyDoll · September 29, 2025

That depends which worlds you want to make swimmable.

S
StrawberryBunBun · September 24, 2025

this is amazing!

L
Luna_del_amor · September 18, 2025

Thank you very much for such a great mod!!I am very sad about its impossible to become swimmable Windenburg island… and what about purple skies by lotharihoe?Does it conflict with your mod?

N
NerdyDoll · September 20, 2025

Yes, other lighting mods will conflict with it. Windenburg Island is not possible unfortunately but Island Bluff is, so that will come soon!

F
Fr0g.R4ve · September 16, 2025

Will the Sunblind version work for Twinkle Toes? I believe its one of softerhaze's lighting mod as well.

N
NerdyDoll · September 20, 2025

If that's a separate lighting mod then unfortunately no. :(

N
NayaMasters · September 16, 2025

Thank you so much for adding the Sunblind version! I was so torn between the two. Thank you!👑👑👑

K
Karo · September 14, 2025

Hi NerdyDoll, thank you so much for making such a high requested mod, this is so exciting!! May I ask if we have to do the step of changing the Areas and Delta Folder each again after we repair the game? I usually replair after each patch, do I have to re-do these steps after that?

N
NerdyDoll · September 15, 2025

Yes, patches usually clear world files, so unfortunately after a game update you have to, especially if you repair the game.

М
Марина Хоткевич · September 14, 2025

OMG!! It's awesome!!

M
Melly · September 7, 2025

You just changed the whole game for me.... wow. thank you!

C
Cristina Vivalda · September 7, 2025

Hi, I installed your mod (also the new one with the others world) but my sims can't swim... I don't know what's wrong... could you help me? I install all world under: C:\Program Files\EA Games\The Sims 4\Data\Shared\Worlds\Areas as per your attached instructions... Thanks a lot!

N
NerdyDoll · September 7, 2025

It's very important to replace the files in the Delta folders too! Delta folders are the main files read by the game. I hope that will solve the issue, if not don't hesitate to reach out again

t
talina Laslie · August 30, 2025

I only see an option to wade. don't see one to swim or create water vehicle.

N
NerdyDoll · August 30, 2025

Please make sure that the new world files are added to the Delta folders.

L
Lxllijohannaa · August 18, 2025

I don’t get how to make this work in the Game..

N
NerdyDoll · August 19, 2025

Hi, which one are you having trouble with?

M
Martina Horvat · August 9, 2025

OMG! It is insane that we couldnt swim in Brindelton Bay, a perfect coastal town! I wish we could swim in Granite Falls, there is really not much to do there and this would make summer vacations so much better. Please also make water around Windenburg island swimmable! Thats another spot I always go to and wish we could swim there. Thank you for amazing work!

N
NerdyDoll · August 9, 2025

Swimmable Granite Falls is also coming soon! While the island in Windenburg can't be swimmable due to its shallow water, the Island bluff can be with some small modifications so it's also coming soon along with several other worlds.

C
Chieh Huang · July 30, 2025

A wonderful mod I've been waiting for since the release of Brindleton Bay! Thank you thank you thank you! One note, I noticed in the 'swimmable' areas, visitors/npcs/walkbys spawned with random hats on both cc and maxis.. I don't know if it could be caused by the changes of the world file..

N
NerdyDoll · July 30, 2025

Hi, seems unrelated as I didn't touch the spawning points or other files responsible for that.

K
Kyle Salinas-Simmons · July 24, 2025

Soo I’m trying to use this mod, I think I’m doing something wrong because it’s not working for me… please help

N
NerdyDoll · July 24, 2025

Can you please join my Discord?

M
Morzat · July 22, 2025

Thank you so so much for this! You have no idea how much I wanted to have more swimmable places! I understand some waters are too shallow, but is it possible to back float at least or just play in the water or use floaters and sunbathe?

N
NerdyDoll · July 22, 2025

Unfortunately the game ties these interactions to water depth so not likely, only wading is possible. But good news is, there are many more worlds coming soon which were made swimmable! 😊

m
mason S · July 20, 2025

Thank you for this helps expand the game for me I hope you keep expanding swimable areas

N
NerdyDoll · July 21, 2025

Thank you, I do have plans for more but unfortunately not all worlds can be swimmable.
