About The River

The South Fork Rio Grande, popularly known as South Fork, sits surrounded by the majesty of the Colorado Rockies. The vibrant river has thrilling stories to tell from the annals of time.

South Fork’s rich history is intertwined with the Ute Indians, trappers, miners, and homesteaders. The Ute Indians were the first to spot this paradise. Boasting a hunter-gatherer culture, they held the land sacred.

  • The Gold Rush of 1870 sparked a frenzy, breathing life into the dormant town. Miners flocked in large numbers, eagerly seeking their fortunes.
  • The Denver & Rio Grande Western Railroad’s arrival in 1882, further boosted the town’s development, transporting vital goods and people.
  • Finally, homesteaders settled in the late 1800s, their efforts transforming the rugged terrain into a flourishing and lively community.

Today, South Fork stands a testament to the resilience of these early settlers, enchanting visitors with its untouched landscapes and vibrant history.
