The Big Thompson River corridor offers various hiking opportunities. A notable option is the scenic 5.5-mile Dunraven Trail. Additionally, the river serves as a gateway to the extensive trail network within Rocky Mountain National Park, providing countless choices for hikers of all skill levels.
U.S. Highway 34 closely parallels much of the river from Estes Park to Loveland, providing numerous access points and associated parking areas. However, parking can fill up quickly, especially during peak seasons and on weekends. Arriving early in the morning is highly recommended to secure a spot, particularly near popular trailheads or fishing access points.
Yes, the Big Thompson River area includes dog-friendly walks. While specific regulations can vary, many trails outside of Rocky Mountain National Park (which has strict pet policies) allow leashed dogs. Always check local signage and be mindful of wildlife and other visitors. Remember to pack out all waste.
For experienced kayakers, sections like "The Big Tommy" run near Estes Park offer a thrill. For rafters, there's an almost 8-mile stretch in Larimer County featuring challenging Class III-V rapids. During summer months, when water levels are lower, tubing is a popular and more relaxed activity, especially around Fairgrounds Park in Loveland.
To fish in the Big Thompson River, you will need a valid Colorado fishing license. These can be purchased online through the Colorado Parks and Wildlife website, or at various sporting goods stores and authorized vendors throughout Colorado, including in towns like Estes Park and Loveland.
Absolutely! Beyond gentle hikes and picnicking, families can enjoy tubing during lower water levels, particularly around Fairgrounds Park in Loveland. Wildlife watching is also a popular activity, with opportunities to spot various species along the riverbanks. The scenic beauty provides a great backdrop for outdoor family time.
Weather along the Big Thompson River can vary significantly due to its diverse elevation and terrain. Summers are generally warm and sunny, but afternoon thunderstorms are common, especially in the mountains. Winters bring cold temperatures and snow, particularly at higher elevations. Always check the forecast for your specific destination along the river before heading out, and be prepared for sudden changes.
Yes, the Big Thompson River flows through or near several towns that offer amenities. Estes Park, at the river's upper reaches, and Loveland, further downstream, both provide a wide range of cafes, restaurants, pubs, and accommodation options, from hotels to vacation rentals. U.S. Highway 34, which parallels the river, also has various services along its route.
The river originates in Forest Canyon within Rocky Mountain National Park and flows through the serene Moraine Park. It then enters Lake Estes before carving its way through the spectacular 25-mile long Big Thompson Canyon, known for its dramatic cliffs. Additionally, four of its crossings/bridges are listed on the U.S. National Register of Historic Places, adding historical significance to its natural beauty.
While some sections of the Big Thompson River may appear inviting, wild swimming is generally not recommended due to strong currents, cold water temperatures, and potential hidden hazards like submerged rocks or debris. The river's flow can be unpredictable, especially after rainfall or during spring snowmelt. Tubing in designated, safer areas is a more common and recommended water activity.
To avoid crowds, consider visiting during off-peak seasons (late fall, winter, early spring) or on weekdays. Exploring less-trafficked access points along U.S. Highway 34, away from the main towns like Estes Park, can also lead to quieter experiences. Early mornings are generally less crowded than mid-day, even in popular areas.
The Big Thompson River is named after fur trader and explorer David Thompson. It has a significant history marked by devastating floods, notably the catastrophic flash flood on July 31, 1976, and another major flood in September 2013. These events underscore the river's powerful natural force and its impact on the region.
