Background:
I LOVE, LOVE LOVE LOVE, this series, and it honestly healed me from a lot of my troubles during my times in life, everything was just so stressful and Yuru Camp just feels like looking at a Student Album, a magically nostalgic experience that takes you back to the days where life is simpler.
When this anime got a season 3, i was HOOKED and decided to watch it for myself.
(Don't mind the edited screenshots you'll see later in the review, and there will be some spoilers, you have been warned.)
Animation: 
New studio, means new direction.
And EVERYTHING that the new studio, which is 8-bit, has brought to the table gives Yuru Camp the same vibe, but with even better quality to boot, and better sequenced, and thus, more memorable parts.
It isn't necessarily all there, as some parts that were present in the 1st and 2nd seasons of the show is not in here (E.g the camping advice at the end) but it is compensated by just how, stellar everything looks.
Every character looks a lot more different than they were 2 seasons ago, with noticeably smaller and darker irises, which is a welcome addition.
Another thing i like is the opening and ending, they all have different vibes
Just look at the animation in this part of the opening (0:43 - 1:14), they DIDN'T NEED to go this hard for an opening, but they did it anyway.
The song that accompanies it, "Laid Back Journey" is much faster its predecessors, and it's probably the only opening songs i'm happy to listen over and over because of this reason.
Next is the Ending.
It even shows the song name at the start, which i really like.
It's nothing too crazy like the opening, but it still invokes a nostalgic feel, a recap of events happening during the episode is shown in the ending, and it changes depending on which episode you're watching, it is kinda like a trip down memory lane for Nadeshiko specifically.
Characters:
Every single character here has something going for them that makes them unique and special.
Let's start with the main cast:
Rin:
There are some very interesting backstory regarding her grandpa and how his way of camping influenced her, most notable in the First Episode.
it kinda abruptly flip flops between young and teen Rin trying out camping but it's not all that jarring, as eventually Rin gets to light the fire, using her Grandpa's way.
She still cares for Nadeshiko and asks her from time to time, and when she's with Nade, they are glued together (and in a good way), and she will always make sure the bond will never break at any moment.
She is the main source of motivation for others to solo camp, much like what her grandpa did, and that influence makes her have an endearing soul.
___
Speaking of which, moving onto Nadeshiko (which i will call "Nade" from now on because it sounds cuter):
___BY FAR my favorite character in this entire season, and it's not just I like energetic girls.
She as a character i found to have the most significant change from season 2.
As established before, she once tried solo camping, and she even eat food alone.
Now, she has been experimenting and cooking different types of food, by her own, and that alone really makes her characterization unique.
when she cooks the food for the others, and they think it's delicious, it's honestly really heartwarming, and it is not just one food, it's many others too, which is the biggest icing on the cake you can get of her.
Very very charming and her energetic and always-at-the-move charisma just makes her so memorable.
It's always delightful seeing her enjoying something, even more so than the other characters.
Her Cherry Blossom camp part with Sakura is also wholesome too, seeing her being this vivid at everything when traveling with her sister is always entertaining to watch.
Next is Aoi, (Chi)aki, and Ena, I'm putting all of these together because they all have the same kind of story with each other, with minor differences.
Still as funny as ever.
Their ENTIRE trip (which is called "Bus Camp") is full of comedic moments, and even if the camping trip had some fictional elements, it enhances the comedy even more, which is dandy.
Chiaki is also making home made sausages, which, although made EVERYONE skeptical, she has convinced everyone to try it out, and to their surprise, they actually enjoyed it
I also pretty like her pizza addiction.
Her inclusion in episode 10 is also worth noting, much like with Nade in season 2, she wants to give solo camping a shot.
Aoi decides on what to do after eating, and it's nerve-racking seeing all 3 trying to decide where to go, while not missing the bus for camping.
it's a very long and grueling walking process, and i kinda feel bad for her, seeing everyone's sleeping right after that hot spring
Ena, now it's a little bit of a different story for her, she still does get along with Rin, but not nearly as much in this season, as Rin is travelling with Aya.
again, contributing to the whole Bus Camp story she is pretty chill, unlike the other 2 that are mostly very insane (in a funny way).
___
Another character worth noting is the teacher, Toba(-sensei).
___
Despite her crippling addiction to sake, she still supports the entire camping club, and does make good decisions to help the camp running successfully.
She's more or less just a comic relief, way more so than the other characters, but she's still charming regardless.
___
This season introduces new characters that we haven't seen before, those are:
___
Aya(no):
___
With a big shoe to fill, and being a quite late character into the series, Aya needs a lot to make her good, and to my surprise, the script did succeed in making me caring about this character.
She initially goes with Rin with the same kind of scooter Rin uses.It's pretty funny seeing the two struggling on a lot of suspension bridges, and even have the willpower to even go to a dangerous one.
It was later revealed that Aya is Nade's childhood friend, and seeing them meet each other after long time sent chills down my spine, watching them looking at the entire trip that Nade has to go through, it serves both character development for both Nade and Aya, even if it's short.
___
Mei and Ema (not to be confused with Ena):
___
Decent side characters that breathes more life in the Yuru Camp world, nothing else to note.
They have quite intrinsic personalities though, and i want to see more screen time for these characters in the future.Story: 
Every element of the original 2 seasons (Aside from the aforementioned ending camping advice) are all present here.
You will still have your hot spring scenes, and educational parts.
the pacing is still quite slow, but it keeps that steady motion all the way to the end.
Every single building and part of the series is very well-introduced, and it is always lively, even in the most silent moments.
It still ends with the entire cast going into one campsite together, following the tradition of the other seasons, which is also a great quality.
___
Overall thoughts
___
If you enjoy Yuru Camp, especially when you're getting that far into the series, I highly recommend you checking this out, you don't even need to watch the movie, as this is a direct sequel to season 2 (following the manga).
