The BCGov't website for locating Forestry campgrounds.
http://www.sitesandtrailsbc.ca/search/search-location.aspxThe lakes district is ripe with good spots.
Little Fort...about 1/2 K past 24 turn off, is a great overnight spot. Used it. Good turning about place.
Up 24..Latremouille Lake has a rec site. As does Goose Lake. Phinetta Lake too.
100 Mile House..turn left at the BC Info building and drive on past..about 1/2 K...look left at the logs by the lake. Swing around so you can watch the birds.
Also the Save-On lot and they have wifi.
108 ..past the airport..51°45'03.8"N 121°20'48.3"W
Greeny Lake, 13 K North of Lac La Hache on Timothy Lake Rd. says pay after May 1st.
A pretty neat spot just out of Quesnel Forks...Q Forks Rec Site.
If you need to stop in Williams Lake..the Save-on lot, with wifi. Or the lot to the east, Staple..level no wifi tho.
Quesnel..about 15? Ks north..a Rest Area on a Hush Lake..is great spot.
I see you are going north from PG..I have no knowledge of the Hart. Been years since I went up that way.
