I'll be visiting Los Angeles in May and one of the things I would like to see is the river culverts featured in so many movies (quick visit and a few photos). The section I'm most interested in is between 1st and 7th streets. Does anybody know if there's a tour that includes that? I would visit it during the day but... Is it a dangerous zone? Is it possible to walk along the culvert itself?

There are many bridges crossing the river. Would a couple of photos from one of them work for you? If so, it might be easy to park up nearby and walk a couple of hundred yards to the middle of a bridge. Just check out the area first and do what you can to minimise the prospect of becoming a victim of crime.– NickApr 4, 2019 at 19:53
Here is the short story. The Los Angeles River in downtown LA is really not visitable.
Here is the long story. There are portions that are very visitable. Those are just not the ones you see in movies.
http://lariver.org/blog/explore-la-river is a good resource for what is available. The picture at the top of the site (4/3/2019) is no where near downtown LA. I think it is farther north in Glendale.
If I wanted to see the LA River and I was in downtown, I would take the Metro Gold Line and get off at Pico / Aliso. There is a good pizza place there, Pergatory Pizza. It is a pleasant walk over the river. Downtown's building are in the background. It is a good use 1/2 hour.
