However, well behaved dogs are allowed in certain areas as long as they are on a leash six feet or shorter, including: parking lots, roads, campgrounds, and picnic areas as long as they do not make noise that impacts visitors or wildlife. Of course, owners must always clean up after their pet.
Do I need reservations to enter RMNP?Yes, reservations are required to enter Rocky Mountain National Park during peak times (late May through mid-October). The park uses a timed-entry permit system to manage visitor flow and protect natural resources.

Reservations are not needed outside of peak season or outside reservation hours.
Is camping allowed in RMNP?Yes, camping is allowed in Rocky Mountain National Park, including established campgrounds and backcountry camping. The park has five designated campgrounds: Moraine Park, Glacier Basin, Aspenglen, Longs Peak and Timber Creek. These often require reservations and include a table, tent pad, and fire grate. Rates range from $30-$35/night for standard sites & $50-$70/night for group sites. For a more remote experience, backcountry camping is available but requires a permit. Always check seasonal availability and regulations, as some campgrounds close during winter.
Am I allowed to fish in RMNP?Yes, fishing is allowed in Rocky Mountain National Park in accordance with Colorado state fishing regulations. The park offers a variety of lakes and streams where anglers can fish, though some areas are off-limits to protect sensitive ecosystems. No special fishing permit from the park is required, but you must have a valid Colorado state fishing license. Be mindful of seasonal restrictions, catch-and-release rules for certain fish species, and specific regulations for each body of water.

When is the best time to visit Rocky Mountain National Park?

The best time to visit RMNP depends on your desired experience. Each season has its own charm depending on what you're looking for. The park's high elevation terrain exceeds 14,000ft in some places. With this comes fluctuating temperatures, potential altitude sickness, & drastic rapid weather changes, including sudden thunderstorm, snow & unexpected cold. Plan to dress in layers and bring gear for both warm and cold conditions.

Summer (June to September):This is the most popular season, offering mild temperatures, open trails, and full access to scenic drives like Trail Ridge Road. Afternoon thunderstorms are common & can be dangerous, so start early & avoid treeline or above by noon. Be prepared for crowds and make reservations where required.
Fall (September to October):This offers beautiful autumn foliage and elk rutting season, providing unique wildlife viewing opportunities. It's a quieter time with fewer crowds. Some services may begin to close by October, and temperatures can drop significantly.
Winter (November to April):This season is ideal for a quieter experience with snow sports like snowshoeing, skiing and winter hiking. Many higher roads and trails, like Trail Ridge Road, close due to snow. Prepare for extreme cold and rapid weather changes.
Spring (April to June):Lower trails start to thaw, and wildflowers begin to bloom. Higher elevations can still be snow-covered, making some trails inaccessible. Crowds are lighter, but weather can be unpredictable with sudden rain or snow showers.

Bringing the right clothing and gear is critical for success in mountainous high altitude areas. Preparing for your RMNP adventure by carefully planning. Where you will be, what you will do, and when you will be there all impact regional weather significantly, with drastic shifts in weather happening suddenly throughout seasons and hourly on any given day.
