As one of the largest reservoirs in Colorado, Lake Granby is a top spot for ice fishing, and home to some of the best trophy trout fishing in the state.

Ice Fishing Season

Ice fishing typically begins on Lake Granby in early January and goes through late April. Foot traffic can start as early as the last week of December and snowmobiles and ATVs can typically be seen on the ice by late January.

Snowmobiles, ATVs and Vehicles on the Ice

Make sure to check ice depths,  as the ice can be inconsistent. Use caution and avoid areas that are shallow with exposed rocks that can heat up and soften surrounding ice. Always carry safety equipment, including shovels, ropes, and a throwable flotation device. Snowmobiles operated on public land or trails in Colorado must be registered with CPW.

Access Points and Parking

Lake Granby is part of the Arapaho National Recreation Area. Annual or day vehicle passes are required and can be purchased online at Park and access Lake Granby at Sunset Boat Ramp, Stillwater Boat Ramp, Cutthroat Bay and North Shore Marina.

Lake Granby FIsh Species

Where to Find Outdoor Gear in Granby

Ice Fishing Events

The 3 Lakes Ice Fishing Contest is the longest-running ice fishing tournament West of the Mississippi and held on Lake Granby, Shadow Mountain Reservoir and Grand Lake. This family-friendly event is held in late January and offers tens of thousands in cash and prizes.

Ice Safety Reminders

Like any outdoor activity, ice fishing can pose certain risks that can be mitigated by proper education. If you are new to the sport, take time to acquaint yourself with ice fishing safety protocols and resources including ice fishing safety information from CPW.

In addition, always remember to dress appropriately for very cold weather, including waterproof boots and an extra set of dry clothes. Bring a safety kit with shovels, ropes and a throwable flotation device.

Responsible Recreation & Environmental Sustainability

Please remember to clean up your fishing site and pack out all trash. Follow the Leave No Trace principles: plan ahead and prepare, travel on durable surfaces, dispose of waste properly, leave what you find, minimize campfire impacts, respect wildlife, and be considerate of others.
