We saw the brown sign from I-5 and decided to explore Iron Gate. It was an easy 8 miles to the reservoir and another 5ish to the campground. There are a dozen or so spots right on the water. Water spigots for campers although they hadn’t been turned on. Johnny on the Spot toilets. Absolutely nothing fancy but relatively clean and safe place to spend the night or camp for a few days. Which we’ve done thrice now!
