Sun Protection

At over 12,000 feet above sea level, RMNP is one of the highest national parks in the US and much closer to the sun than wherever you’re coming from. Sunglasses are a must.

Pack more sunscreen than you think you’ll need, and reapply it every hour or so. Wearing a hat and sun-protective clothing can make sunscreen application less of a chore—you could also go the parasol route, but you’d probably get laughed off the mountain.

    Despite the high elevation, summer in Rocky Mountain National Park can get scorchingly hot. Make sure to pack plenty of water for exploring. If you plan to hike, a backpack with a water bladder is an easy way to comfortably carry three liters and sip as you go.

    Moisture-wicking clothes

    Between the heat and the physical exertion of high-altitude hiking, a visit to Rocky Mountain National Park in summer is going to make you sweat—a lot. Keep yourself comfortable with lightweight, moisture-wicking pants, shorts, and shirts.


    The air is colder 14,000 feet up, and wind gusts are common. What seems like a hot summer day can quickly get uncomfortable if the wind picks up or the sun goes behind a cloud.

    Always bring a jacket, a hat, and thin gloves in case you need them. And be sure to pack a raincoat—Colorado may be a desert, but afternoon showers are always possible in summertime.

    Tour Holzwarth Historic Site

    This little-known historic site was once the property of John Holzwarth and his family, who immigrated from Germany over a century ago and built cabins for themselves and their guests.

    Now the property is part of RMNP, and volunteers offer daily tours during the summer months to give visitors a glimpse into the life of Colorado homesteaders.

    Go Stargazing

    Rocky Mountain National Park is a wonderful park for stargazing, and summer, when the evenings are at their warmest, is the perfect time to do it.

    Because Trail Ridge Road is above the tree line and on, well, a ridge, you can pull over pretty much anywhere for a gorgeous view of the stars.

    If you’re up for a short night hike, Dream Lake and Bear Lake are easily accessible places where you can see the starry sky twice—up above and reflected in the water.

    Reserve Your Timed-Entry Permit

    Rocky Mountain National Park is currently piloting a high-season timed-entry permit reservation system—meaning if you visit between May and October, you’ll need to choose a day and time and reserve your spot online in advance.

    There are two types of permits, depending on where in the park you want to go: the Bear Lake Road Corridor, and the rest of the park. Each permit gives you a two-hour window to enter the park, with no set departure time.

    Start your day early

    The crowds in RMNP get pretty dense in the summer months, so get an early start to beat the rush. This also helps if you plan to do a Rocky Mountain National Park summer hike—it’s cooler in the morning, and you’ll give yourself extra time for water breaks and photo ops.

    Pack snacks & a lunch

    With 415 square miles of meadows, forests, and tundra, Rocky Mountain National Park isn’t exactly small. You can easily spend a full day here just driving around, so make sure to pack food and drinks. If you plan on hiking, bring plenty of water and high-energy foods like nuts, jerky, or protein bars.

    If you don’t bring any, be sure to pick some up in Estes Park, where there’s a Safeway and some other shops.

    Don’t Let the Bugs Bite

    Mosquitos and other pests are mercifully uncommon in Colorado, but they do pop up in Rocky Mountain National Park in summer. Mosquitoes especially like to hang out near bodies of water, and they’re known for carrying the dangerous West Nile virus.

    It’s a good idea to pack bug spray in case you run into them. Also, be sure to check yourself for ticks at the end of the day.
