For me, I do most of my thinking at night before bed and most of my writing at work on the weekends.

I get my ideas a lot while daydreaming at my desk. The window in front of my desk looks over a giant mango tree, and it's monsoon season. I'll make myself a cup of tea, put on some music, and try to come up with ideas. It's a lovely atmosphere to write in. 

Usually inside my head, the place is nice and empty most times a day, quiet too.

That's my secret Cap, I'm always daydreaming.

The blessing and curse of being a dyslexic.

In all seriousness anywhere that I become still too long is a perfect place to think.

I usually do all my writing on my desktop, so I'm not very mobile. I have written on my phone. It reminds me of the days I would write my stories in spiral notebooks, but it's not something I want to continue doing. Keyboard on my phone is too small.

I've found myself much more able to think and write while in camp. Granted, I'm made to do stuff while training, but it does help in me entering my mind palace and thinking up of what to write next.

I prefer to think about my story outside of my house when I'm trying to find new places. However, I usually write everyday on my afternoons. 

Wow, everyone has such inspiring answers. Mine is, er...

I pace around my apartment and mull over details. When plotting, I'll do this for days at a time, usually from the moment I wake up until the moment I go to sleep, if I can.

I don't recommend it. Too uncomfortable, too many people. It's easy to get distracted.

Thinking? Anywhere. I have the fun ability to randomly zone out in the middle of any activity because I got an idea for my story.
Writing, I write at my desk. But I prefer to do it at night, in the dark, alone. I write best then when I feel like there's nothing in the world but me and my story.

My best writing ideas is when I take long walks.  Like first thirty minutes of walking, I may be all over the place and can't really concentrate on anything in particular. But like 30-40 minutes of walking at medium pace,  somehow it starts to come very easy for me.  I sort of get transported in it.  I can go like that for an hour, just walking slowly.  And when I get too many ideas and am afraid I may even forget about them, I stop to put my ideas down on my phone.  I bet I look very weird, but I don't care.  Some people walk their dogs, I walk my brains.

Same for me! I really enjoy taking a walk and figuring out where to take the story next and how to fix potential plot holes and such.

Also this! I really like talking myself through my ideas, and it helps to set up a table where I can have paper or flashcards to jot stuff down. I sometimes just walk around figuring out my story until I have something worth writing down.

Bus rides is for thinking. 

5 in the morning is for writing

At my table. I have found myself to be able to write anywhere but speed is good only at my computer

Thinking - depends. I'm a problem solver, so when i hit a story road block where I can't force the words, I have to stop to think about the problem. The thinking takes time - days/months because it's a subconscious process. I do have to pay attention to the stuff I say about the 'problem'. example, a recent project I'm working on, I hated the first chapter. I finished it, sent it off to my publisher, but absolutely hated it to the point where I couldn't do chapter 2. Lucky for me it was a weekend, so I had a lot of other activities to do where I could think consciously and subconsciously process the problem. I hated the chapter but why?
I was instructed to have dialogue - which I had none. So could I add some? Where? 
Subconsciously, I decided to change POV characters. I don't have enough time to really build up a repour for all of the characters I have in the first chapter and within 1,000 word limit. So focusing on one, for the immediate chapter, while giving the MC time to breath and grow into his role through the eyes of a character I'm very likely to murder by the end of chapter 4.
I found I struggle to focus on thinking about the writing - I have to let it sort itself out a lot of the time. But knowing when to step away and work on something else and when to come back to it, is very important.
When I try to do my active thinking is during a bath, as I try to get comfy for sleep and walks. Walks often turns into a session of all of the social things I don't understand or managing my finances in my head. I avoid listening to podcasts/audio books during this time because the subconscious NEEDS to work, even if I'm talking finances and planning a move overseas with myself. Walking was something I used to do to manage anxiety.
To get inspiration accidentally - that's as I'm getting comfy for bed or if I hit a nice sound track. 
To get inspiration intentionally - I rush my drafts, and have recently started burst writing just to clear the blank page paralysis - I'm a better re-writer than I am a writer.

Different places, sometimes in bed, sometimes when walking. That last can be dangerous as I can zone out and lose my self awareness and almost get run over!

..... I like to think in the shower. I am often forced to think while laying in bed. I can only write in the living room, I wish I could write in more regular times.

I think when I fish or hike or work outside - anything that I can kind of do on autopilot.

I write seriously on Saturday mornings and some evenings - but a LOT of my writing gets done in 500-word gushes when I get a new idea or insight. Threading them together - that's what Saturdays are for.

I work best at night. Usually in my bedroom, sometimes with music--mostly for the outlining and such, but when it comes to actually writing the story, I need it to be quiet. I like to work away from people and in a cozy space. No distractions this way.
