Antero Reservoir sits at 9,000 feet in the heart of South Park, just off Highway 24 between Fairplay and Buena Vista in Park County. It is one of Colorado's most productive trophy trout fisheries, drawing anglers year-round who chase rainbow and brown trout that regularly exceed 20 inches. The reservoir is free to access with no state park pass required, only a valid Colorado fishing license.
Fishing at Antero Reservoir is the main attraction. The lake holds both rainbow trout and brown trout, with fish known for their impressive size and deep orange meat. A strict two-fish limit keeps the population healthy, and anglers can use flies, lures, or bait. Shore fishing is accessible from both the north and south sides, though a boat gives you a significant advantage on this shallow reservoir. Be aware of submerged rocks near the launch area that can damage boat motors. Boat inspections are required before launching. Aquatic plants, particularly milfoil, can make summer fishing more challenging, so many regulars prefer spring and fall trips.
Ice fishing at Antero Reservoir is legendary in Colorado. The south side of the reservoir is the go-to spot during winter, and on weekends the ice can be packed with anglers. Experienced ice fishers report consistent action with trout in the 16 to 23 inch range. Salmon Peach bait is a local favorite that consistently produces bites. Ice conditions vary, so always check thickness before heading out.
Free camping is available on-site with spacious gravel pads and generous spacing between sites. Note that as of early 2026, camping fees may have been introduced, so confirm before your trip. The campground is first-come, first-served with vault toilets and trash service, but no hookups, no shade, and no potable water. RV access is easy, with many reviewers noting it as one of the better free RV-friendly spots in the state. The south shore offers the main camping area, while the north shore is better suited for day use.
Wind is the defining challenge at Antero Reservoir. Afternoon gusts are nearly guaranteed and can turn the water rough quickly, so plan to fish early morning for calmer conditions. There are zero trees anywhere on the property, meaning no natural shade and full sun exposure. Bring sunscreen, a hat, and an umbrella or portable shelter. Bug spray is also essential, as midges and mosquitoes are thick near the shoreline, especially in summer months.
Wildlife viewing adds another reason to visit. On the drive in from Fairplay, keep an eye out for elk herds, pronghorn antelope, and the locally famous white buffalo. The open landscape also delivers panoramic mountain views in every direction, making it a worthwhile stop even if the fish are not cooperating.
