Five Things Every First-Time Visitor to Rocky Mountain National Park Should Know

Rocky Mountain National Park (RMNP) is a dream destination for hikers, anglers, photographers, and outdoor enthusiasts from all over the world. If it’s your first time visiting, a little knowledge ahead of your trip will make your experience safer, smoother, and far more enjoyable. Here’s what you need to know before you lace up your boots.

1. Altitude Will Affect You — Prepare for It

The park’s elevations range from about 7,800 feet to over 14,000 feet at the summit of Longs Peak. If you’re coming from sea level or a low-elevation city, don’t underestimate the effects of altitude. Shortness of breath, headaches, and fatigue can hit fast.

Tips:

• Arrive a day or two early to acclimate if possible.

• Drink more water than you think you need.

• Avoid alcohol your first day at altitude.

• Start with easier hikes before attempting challenging trails.

2. Weather Changes Quickly (and Sometimes Dramatically)

You might start your hike in sunshine and find yourself facing a thunderstorm by lunchtime. Afternoon thunderstorms are common, especially in July and August.

Tips:

• Always bring a rain jacket, even on sunny days.

• Start your hikes early (before 8 AM when possible).

• If you hear thunder, descend below tree line immediately.

3. Park Access is Regulated — Reserve Ahead

Since 2020, RMNP has implemented a timed entry reservation system during peak months (May–October). If you show up without a reservation, you may not be allowed into the park during high-traffic times. FYI (A Guided tour allows us to enter the park at anytime due to our special permits).

Tips:

• Book your entry permits online in advance.

• If you're joining a guided tour, your outfitter may handle permits.

• Early mornings and late afternoons often have more flexibility for entry.

4. Wildlife Encounters Are Likely — Stay Safe

RMNP is home to elk, black bears, moose, bighorn sheep, marmots, and more. Spotting wildlife is thrilling, but remember: these animals are wild and unpredictable.

Tips:

• Stay at least 75 feet away from elk and deer, 120 feet from bears or moose.

• Never feed wildlife.

• Carry bear spray if you're in backcountry areas (check local regulations).

5. Leave No Trace Principles Are Not Optional

The park sees over four million visitors each year. Preserving its beauty means everyone must do their part.

Tips:

• Pack out all trash (even biodegradable waste like orange peels).

• Stay on marked trails to protect fragile ecosystems.

• Respect wildlife and other visitors by keeping noise to a minimum.

Rocky Mountain National Park is a place of wild beauty, towering peaks, and deep serenity — if you come prepared, your first trip will likely not be your last.
