This was a bit tight pulling our 35 ft fifth wheel, but just be careful with a couple of the turns. The campground roads need some work in spots - there were several potholes as deep as 6-8 inches - enough to jar your teeth out If you're not watching for them.
Sites are very nicely spaced with lots of sunlight and dappled shade. Everyone was pretty quiet and well mannered. I was a bit surprised by how empty this campground was during the week, despite it being summer. Mon-Fri I would say it wasn't more than 30-50% full. It did fill up on the weekends.
Stayed here two weeks in July. You're at 6000ish feet, so the weather is delightful in the summer. Some nice hiking is within walking distance, and Echo Lake is a decent workout from the campground.
There are several pressurized water spigots spaced around the campground, but oddly, they don't have a standard garden hose fitting. I have a 55 gallon bladder I fill and then I use a pump to fill my rig from the bladder. This saves me from having to move the rig to get water. The camp hosts site did have a standard hose fitting and he had no problem letting me fill the bladder several times during my stay.
There is a day use area (Red Bridge) across the street on Georgetown Lake, but there's not much there. Only a couple picnic tables and a boat ramp. No shade. No place to let the dogs swim and play fetch. I recommend going east back up Montana Route 1 a mile or so to the Grassy Point boat launch. Large parking lot with plenty of doggie access to the water for playing and fetching.
All in all, a nice place to spend a couple weeks.
