Confirmed boondocking place from overnightrvparking.com:
Address:13420 Coal Mine Ave, Littleton, CO 80127
39 36.4356 N, 105 9.1104 W
39 36 26.14 N, 105 9 6.62 W
Directions:SR 470, Exit to Bowes Ave, then E on Bowes Ave to first traffic signal beyond interchange, R on Coal Mine Ave ~ 0.2 mi to store on R.
For less crowded part of lot, enter 2md Walmart driveway.
RVer reports that Overnight RV Parking is allowed, confirming reports from Aug 2010. Park parallel to curb on outer perimeter of lot, either as far from store as possible, or on S side of store closest to SR 470. Lot entrance driveways lead to awkward turns; this & many lot islands make this a difficult lot for maneuvering larger rigs. McDonald's in store.
There's also a Sams Club not far from the WalMart at 505 S Broadway, Denver
