Tonijim,
I think you might mean INDIGO Bluffs RV Resort at M-72 and CR 677. We camped there several times back 25+ years ago when it first opend as "Sleepy Bear CG".
Was sold later as I was told and the new owners completely rebuilt the CG and added the very nice FHU section closest to the corner of the 2 highways.
Decent location and close to lots of things in SBNL. Nice swimming beach on Lake Michigan at Empire and there's a few places you can park your 32' "C" there but not many. The beach is only a few blocks from the main street so it's even walkable.
At the west end of the main street in Empire and going south takes you up the big forested hill/dune to Empire Bluffs lookoput parking area so you can walk out on the top of the dune for some great views etc. Lots of hanggliders launch from there and some will ride the dune uplift air currents for many hours until they get too tired to go on. Going further south on M-22 takes you to the Platte River and Platte Lake area etc and the NP CG. Adequate/decent grocery stores etc are at Glen Arbor, Empire, Honor, Frankfort, and even Leland which also has fresh smoked there many varieties of fish including local wild caught salmon plus they make a smoked fish sausage right there too. Lots of shopping or window shopping etc. Leland is worth the trip and there are lots of excellent award winning wineries all over the whole region. Bet you never had real 100% Cherry Wine before direct from the orchards. Many varieties to sample. We love it! Traverse City has about anything you could ever need or want in cluding many of the big box stores and outlets.
The SBNL Park headquarters and info center etc is just east of the stop light on the corner of M-22 and M-72. Best to get your info, maps, and ask questions there for the area and they have a very large paved parking area for big RV's behind the building. So many attractions on M-109 that veers left off M-22 about a mile north of Empire. sAbout 30 miles south of Empire is the inspirational roadside park lookout on M-22 just north of Arcadia and what a view.
So many more great attractions and scenic areas and overlooks. Just ask when or if you want to know or anything else as we know the area well. Been going there more than twice a year since the early 1960's.
