Colorado’s first state park, Lathrop State Park is 1,594 acres of recreational enjoyment nestled in the shadow of the Spanish Peaks in Southern Colorado.

The park’s two lakes offer a variety of boating and angling opportunities for all types of water recreation. Martin Lake offers water skiing, power and sail boating. Because Martin is a warm-water lake, it makes it great for swimmers. Horseshoe Lake is a peaceful haven for canoeists, kayakers, sailors and other boaters at wakeless speeds. Catfish, bass, walleye, trout and blue gill thrive in both lakes. Horseshoe Lake is known for its large tiger muskies.

Archery
An archery practice range and parking area is available west of the main entrance of the park along Hwy 160. If you are only using the archery range, no fee is required.

We ask that you treat this area with respect, pick up trash and help the park maintain it for long term use. Thank you for your cooperation.

Biking
Bicycles are allowed on the multi-use Cuerno Verde Trail, or on park roads. No bikes are allowed on the Hogback Trail. The park’s 3-mile closed loop Cuerno Verde Trail is popular with bicyclists. The trail goes around Martin Lake.

Birding
Lathrop is known for the wonderful birding experience it provides.  One of the great birding experiences Colorado has to offer is right here at ​Lathrop State Park.

Boating
​Lathrop’s two lakes offer something for every water recreationist, from the power boater and canoeist to the sailor, swimmer and angler. Because of Lathrop’s location in southern Colorado between the foothills and plains, the lakes’ water is often warmer than most mountain lakes and reservoirs at higher elevations, averaging 75 degrees Fahrenheit in the summer. Bring your jetskis and waterskis and enjoy these activities on Martin Lake.
