Friend always wants to hang in secluded areas, and it’s making me feel weird.

So I’ve known this girl for around a year and a half.
She’s of the very crunchy type. Likes to run, like to hike, likes to go to the beach.
I don’t know if I’m being overly precautious, or she’s naive.
But she always want to run in the most secluded part of this park, 6 miles out where there’s no cell service.
She wants to beach at this part of the beach that nobody can get to unless they have four wheel drive.
Some of these things it’s very easy to write off as “oh yeah she’s just into runnings or hiking”

I suggest things that would be more public and in her category like beaching on the public beach, or jogging through the boardwalks where there is walks of life but still some scenery, it’s a hard no for her. I suggest fishing on a public boat, no. All things she would be into.

The weirdest thing in my opinion she wanted to do was walk in a dark parking lot at 2am. Just me her and another one of her friends.
We went to a carnival, then went out to eat, then after we ate it was 2am. She still wanted to hang out and go for a run at 2am and I’m thinking she wants to take a stroll through her neighborhood.
No, she wanted us to go to a closed park after hours, dark beach, etc.
I just think it’s weird.
So I always take my own car to these events and I agreed to go there thinking it was going to be a well lit busy parking lot. When I followed her there, she routed us to a different location and it was in a bad neighborhood and we all arrived in our cars and they parked next to each other, I had such a weird feeling and I didn’t even park. The parking lot was dark, almost pitch black, and I pulled up next to both and them and told them “I’m out, have a good walk” and I dipped immediately.
I told my mom, boyfriend, sister and coworker about this experience and they all individually told me this behavior is super weird and the want to be in secluded areas is odd.

My mom, boyfriend, sister and coworker have all across the board told me individually that I should stay away from her and follow my gut. Esp after the dark parking lot situation.
How would you feel about this?
