Walking is not a guaranteed cure for insomnia, but regular physical activity can be part of a sleep-supportive routine. The benefit may come from several directions at once: more daytime movement, exposure to daylight, stress reduction and a more consistent daily schedule.
Daytime activity can support sleep pressure
Being physically active during the day helps distinguish active hours from rest hours. For someone who sits most of the day, adding a regular walk may make the day feel more physically complete.
Outdoor walking adds a light cue
Morning or daytime outdoor light helps reinforce the body clock. This is one reason a walk outside can serve more than one purpose, especially after travel or a disrupted schedule.
Timing is personal
Many people can walk in the evening without a problem. If a fast or hilly walk close to bedtime leaves you alert, move the harder session earlier and keep evening walking easy.

Will walking fix chronic insomnia?
Not necessarily. Persistent insomnia can have many causes and may need professional assessment and evidence-based treatment.
