Doing my research but nothing I find refers to how safe it is. Mainly I was wondering if it is around dangerous nieghborhoods or intersections.
there's actually a fair amount of crime in the heights, especially around its fringes. but the bike trail probably is safe
I live in the Heights and take this trail all the time. I have never encountered anything that would make me feel unsafe. Now when I take it all the way to UofH and go down to the bayou trail that first part can feel a little scary. You are under the bridges on a trail riding and there are some homeless that crash there. But I figure that since you are most likely going 12 or more miles and hour, most people cant run that fast.... But the heights trail, I wouldn't worry. If you do just start off at the court house by Washington and ride the bayou, I see cops on horseback out there a lot.

It's safe particularly if you stay between 11th and 610N. FYI the trail is blocked under 610N @ tc jester so if you are going to continue north you will have to go above.
