Short on time so I researched and found a great 2 mile walk/hike.
Take the train to 23rd/Marshall and walk over to the Lower Macleay Park entrance (stairs lead down under the bridge on right and there are bathrooms!).
About a mile to the stone house (the witches castle - a haunted story I believe? You can't miss it...and unfortunately vandalized)
From there sharp right up wildwood trail (and another mile) to another right Holman Lane (that gets you back into the neighborhoods.)
We had a wonderful/refreshing lunch at Rae's Lakeview Lounge (as suggested by someone on this site thank you) . Do it! It felt like a neighborhood bar and all around wonderful.
