I had previously posted this under Table Mountain topic:
The past few seasons they closed on November 15, 2007. In regards to cold temps it depends on what you think is cold. It is not unusual for the mountains to get into the mid 30's to 40's at anytime during the summer. I am most comfortable in the 20 - 50 degree range of temps. But some folks think they are freezin to death at 60 degrees.
The manager of Table Mtn, Lake & Mtn Oak is Daryl Walters. He is a very nice man. You can reach him @ 3526 if you would like to know for sure when they are planning on closing up for the season.
I hope this helps...
In regards to campgrounds with water:
Table Mountain
Lake
Mountain Oak
Peavine
Apple Tree (when I left the water was off due to pump probs.)
Jackson Flat (group campground)
Lupine has a small creek... although you would have to treat the water.
Sycamore Flat in Big Rock Creek
Please note when temps get to freezing usually by the end of October the water is shut off.
I have seen all of the campgrounds fill up on holidays. If they are still allowing campfires down there it could be hard to find a spot. If you can leave on Thursday to have a better chance of first come first serve sight that is best. Rather than Fridays.
