Hartsel Ranch offers a year-round fly fishing experience on the South Platte River, with distinct opportunities throughout the seasons. The spring and fall are particularly noted for their excellent trout fishing, with hatches becoming more active and the fish feeding aggressively. Summer provides pleasant weather for fishing, though the high country can experience afternoon thunderstorms. Winter offers a unique, serene experience with fewer anglers and the possibility of catching large trout in clear, cold water, provided conditions are safe. The ranch provides access to three miles of private water on the South Platte River, renowned for its Gold Medal status. Additionally, guests have access to nearby Antero, Spinney Mountain, and Eleven Mile reservoirs, which offer diverse stillwater fishing opportunities. Spinney Mountain Reservoir is highlighted for its exceptional trout fishing, with rainbows, cutthroat, browns, and pike, and an average trout size of 17-20 inches. Eleven Mile Reservoir also boasts a robust population of trout, with an average of 17 inches and many larger specimens, along with kokanee salmon and carp. Antero Reservoir is noted for its brown and rainbow trout, though it was closed for 2026 at the time of this writing. The 'Dream Stream' section of the South Platte, between Spinney and Eleven Mile, is famed for trophy-sized trout.
