A really great place for a jog or just a relaxing walk in the afternoon.
As the name implies, the park is based around McAlpine Creek (and Campbell Creek as well) and features long winding trails both along and over the creeks as well as through the woods and around a large pond that has a lot of different waterfowl in it.
There are sports fields and places to grill out as well if you bring a crowd with you.
Overall it's a tremendous place, the only drawback is that the people driving on Independence (which goes over part of the trail) will occasionally throw litter out of their cars and it lands in the park.
