I couldn't figure out the name of the playground itself, so this review is for the main playground and not for City Park itself (which we did really enjoy).
a. There seem to be multiple playgrounds in City Park in Denver, but I think this one MAY be the largest it has. It is located near the duck pond and a very short walk to the pavillion. There is a pretty good amount of street parking nearby. Seemed pretty safe to me.
b. The playground is huge and there are A LOT of options for kids to do. There are slides, climbing structures, a merry-go-round looking thing, this bumpy path thing that my son really enjoyed, and even a swing for a wheelchair (never seen that before).
c. The only thing was that there were A LOT of kids there. It was a challenge to find a table and to not feel space invaded. There were even a couple of kids there that weren’t quite kind to my son and his mother didn’t notice or seem bothered by it. It killed some of the fun of the outing.
d. Well made park with lots to do. Busy though so expect that if you go (we went around 10-something). And yeah, and in early July it was HOT. There is some shade by the tables, but if I recall, not on/around the play structures. Plan for that.
