Visitor Comments About San Luis Reservoir
“San Luis Reservoir surprised me with its beauty and tranquility. We spent three days camping and fishing, catching several nice-sized striped bass. The sunrise views over the water were absolutely spectacular, and the hiking trails offered a perfect balance to our time on the boat. Will definitely return in the spring to see the wildflowers.”

The O’Neill Forebay is perfect for teaching kids to fish and enjoy water sports in a safer environment than the main reservoir. We love the spacious campsites at San Luis Creek Campground, though they fill up quickly in summer. Pro tip: visit in late April when the hills are still green but the crowds haven’t arrived yet.”
