Does the Moon Phase Impact Elk Movement in Colorado?

April 5, 2026

Quick Answer

The moon phase impacts elk movement in Colorado, with the best hunting opportunities typically occurring during the new moon phase when elk are more active and less vigilant. This allows hunters to get closer to their prey and increase their chances of a successful hunt. In Colorado's over-the-counter (OTC) elk season, timing can be crucial.

Moon Phase and Elk Movement

Elk movement patterns in Colorado are influenced by various factors, including the moon phase. Research suggests that the new moon phase tends to increase elk activity and movement, making it a prime time for hunters. During this phase, elk are more likely to be on their feet and roaming in search of food and mates. In Colorado’s OTC elk season, which typically takes place during the early fall, hunters should aim to be in the field when the new moon is rising.

Understanding Elk Behavior

To take advantage of the moon phase’s impact on elk movement, hunters need to understand elk behavior and habitat preferences. In Colorado, elk tend to congregate in areas with abundant forage, such as meadows and aspen groves. During the new moon phase, hunters can use this knowledge to their advantage by focusing on areas with high concentrations of elk activity. This might involve scouting for elk sign, such as tracks and scat, and then setting up a hunting blind or stand in a prime location.

Timing Your Hunt

To maximize the effectiveness of the moon phase in Colorado’s OTC elk season, hunters should pay close attention to the lunar calendar. The new moon phase typically occurs every 29.5 days, and hunters should plan their hunts around this cycle. For example, if the new moon phase is on a Tuesday, hunters should aim to be in the field on the preceding weekend or early on Tuesday morning. By timing their hunt with the new moon phase, hunters can increase their chances of success and make the most of their time in the field.
