The best time to visit Rocky Mountain National Park is from June to September when the snow is (mostly) melted and the hiking trails and attractions are accessible. Still, these four months are also the most popular times to visit, so if you'd rather experience RMNP in relative isolation and while wearing snowshoes or cross-country skis, visit between the months of October and May. Whether snow or sunshine, the park is open to the public 24 hours a day, 365 days a year, though some parts may be inaccessible.

From everyday sightings of chipmunks and mule deer to the moving experience of viewing elk in rut (the mating season), the animals in the park let you know that you are part of something truly wild. Some of these critters are harder to spot than others - they might camouflage themselves in the trees or hide in the underbrush - but look closely and you may have an encounter unlike any other.
