So I know there are all kinds of great crawling tracks out there, but when my kiddo was young enough for one I hadn't yet tumbled to Glen Doman or BrillKids...however, as I am in a wheelchair and was determined that A would still be very physically active, we 'invented' several versions that might interest some of you...
As far as a crawling track, we lived in an apartment at the time and used two contoured changing pads end to end, like these, for around $20 as I found them at a second hand shop. I am now struck by just how similar my 'obstacle course' was to a proper crawling track!

Indoor climbing is now being used for brain-injured individuals, physical therapy, stroke rehab, you name it. We built a tiny inclined wall and put our tiny child in a harness (full-body) and she worked her way up a two-foot section by pulling her body using hands and feet in a crawling-style motion. She was tied in so it is basically a pulley-system to assist. In addition, the handholds are textured and in the shape of letters and numbers...she still climbs from A to Z on a much more advanced wall,, and we make loads of games with things like shouting out words that start with whatever letter her hand is on.
It has very similar benefits to brachiation, but additional ones as well. Balane, coordination, spatial awareness, grip, confidence, I could go on and on.
I know it sounds quite complicated but it is really no more complicated than a brachiation ladder, and we worked one in later on the existing setup...
I will hunt down some pictures if anybody is interested.
BTW- my daughter started gymnastics and the first day the instructors could not believe how coordinated, strong, and flexible she was. Considering she much ride in my lap a great deal of the time, is forced to take an elevator instead of stairs, etc, I am exceptionally pleased with the outcomes!
