Canyonlands N.P. Utah

Should be good at least into mid October or no?  Are we talking snow?  Probably, well we've been there before putting up with the white stuff in Michigan, Ontario, Wisconsin, Minnesota, and Montana.

If you don't mind a bit of a drive from Moab--about an hour or just less depending on how you drive,  try Green River State Park in Green River.  Nice shade trees off the river, clean with excellent showers, fire pits etc.  I prefer it over the commercial stack'em up campgrounds in Moab.  Can't remember the name of the resturaunt but try a MOAB Burrito (Mother of All Burritos), it's right on mainstreet.

I know this  is an old post, but I just found it.  We spent several nights in a BLM campground about 5 miles outside of Moab on River Road. There were 2 camping areas there right on the river.  They had large spaces, tables, fire pits and pit toilets but no water or power.  there is a large spring (Matrimony Spring) right at the edge of Moab  that all of the outfitters use for their trips. It is good water and easily available. Ask a local-everyone knows about it. It was a quick drive to Arches and not too far from Canyonlands and Dead Horse Point

We live in Park City and have been down in the area 3 times in the last month, Freemont, the Wedge and goblin valley.  Canyon Lands is the south end of the San Rafeal Swell, a huge amazing area.  Burea of Land Management areas you can do dispersed camping .  Google this for more info on BLM and National forest service camping. This is our preference.  We have a state park pass for access to water and dumps, then dry camp in the surrounding area.  Much easier and quieter then camp grounds.  How ever we do like the Freemont Indian state park with full hook ups.   Nat Goe maps of the area are good.  Fall or spring is the time to be there.  Hauling over the passes after November 1 could be an issue.  

We stop at BLM and NFS offices in the area and ask them where to camp depending on what we are doing, usually hiking.  The Price BLM office was very helpful.  We have had enough bad experiences in camp grounds we like a little more space between us.  It can be hard to get reservation, but mostly we plan a week before for the weekend, depending on weather.
