As has been said, it can be done very briefly but if you want to admire the nature and wildlife more ~30-45 minutes should be plenty. I took even longer than that the first few times
You could walk the whole thing in 10 minutes but that's without pausing to look at anything. I enjoy watching the fish for at least 20 minutes when I go.
30 minutes and we had a baby and two kids with us
Depends on how much you stop, but my toddler and I walked around the trail in about 30-40 minutes (and she’s slow lol).
