Where is Rocky Mountain National Park?

Rocky Mountain National Park is located in between Grand Lake and Estes Park. There are two main entrances to the park, the east and west entrance.

Local Tip: Trail Ridge Road, the high mountain pass that connects the two entrances, closes from late fall through mid-spring.

Most people opt to access Rocky Mountain National park from the east entrance, just 15 minutes from downtown Estes Park. Estes Park offers easy convenience and many of the best hikes in Rocky can be found on the east side.

What is the best hike in Rocky Mountain National Park?

The best hike in Rocky Mountain National Park is easily Mt. Ida. Not only are the views at the summit stunning, but all my fellow hikers out there will love the incredible panoramas you get as you make your way to the top.

Local Tip: Not up for the uphill challenge? Then you should check out Emerald Lake instead or explore the park by booking a Rocky Mountain National Park tour.

What is the prettiest hike in Colorado?

The prettiest hike in Colorado is Emerald Lake Trail in Rocky Mountain National Park. Not only is it home to one of the most beautiful alpine lakes in Colorado, but the hike is well-suited for people of all hiking abilities.

Plus, there are many highlights along the way which include Colorado wildflowers, alpine scenery, stunning mountains, and picturesque lakes.

Backtrack back to the junction and continue on to hike to Lake Haiyaha, the trail does get steep for a little bit, but it’s not too difficult.

Lumpy Ridge often gets overlooked for more popular areas of the park, but that doesn’t mean that the Twin Owls and Lumpy Ridge Loop shouldn’t be on your list. This mellow trail takes you to the Twin Owl rock sentinals, an impressive feature that really does look like a pair of hooting birds.

Outside of the main area of Rocky Mountain National Park, you’ll find Lumpy Ridge, one of the premier rock climbing areas in Colorado.

Climbing aside, this area has some incredible hiking trails. Far less crowded than the Glacier Gorge and Bear Lake area, you’ll find solitude amongst the huge rock formations jutting from the mountainside.

Difficulty: easy with options ranging from moderate to difficult.
Estimated Time: 1.5 hours
Trailhead: Glacier Gorge

12. Nymph Lake

Not up for the full Emeral and Dream Lake hike? Then simply head to Nymph Lake. This forested lake feels like a place where ferries hang out. The calm tranquil waters are home to lily pads and other water life. As one of the best hikes in Rocky Mountain National Park, it’s normally done in conjunction with Dream and Emerald Lake, but if you’re short on time or not into the uphill, it’s an excellent hike in it’s own right.

Just be prepared to continually walk uphill through vast forests filled with pine trees until you reach the summit where you’ll marvel at incredible views of Longs Peak and Moraine Valley.

So, while the hike can feel like a bit of a slog, it’s totally worth the effort for the panoramas at the top. And to access the trailhead, just take Trail Ridge Road about 3 miles west of the Beaver Meadows entrance.

It’s also a great hike if you’re looking for a bit of solitude since not as many people use this trail.

32. The Mummy Kill

More of a trail running suffer-fest than a leisurely hike and should only be attempted by well-seasoned mountain hikers and trail runners.

The Mummy Kill refers to a slog-a-thon challenge that goes over the 6 peaks in the Mummy Range. Not to mention after you summit Mummy Mountain, you’ll be bushwhacking through dense trees for several miles before stumbling onto the Lawn Lake Trail. from there it’s another 5 miles to the car.

PHEW. I’m exhausted just typing that. It’s a serious objective that commands respect and many people train for years just to attempt it.

Distance: 20 miles

Difficulty: Expert
Estimated Time: 11 hours
Trailhead: Long Lake Trailhead. You’ll need a shuttle since this is a one-way route. Park another car at the Fall River Entrance Station.

What is the Hardest Hike in Rocky Mountain National Park?

If you’re looking for a true challenge, you can find in Rocky. The hardest hike in Rocky Mountain National Park that most people know about is the Keyhole Route on Long’s Peak. However, this isn’t really a hike. You’ll be climbing (not hiking) up a mountain. You’ll need a helmet and plenty of Colorado 14ers under your belt before safely tackling this route.

Another challenging hike in Rocky Mountain National Park is the Mummy Kill. This 20-plus-mile gauntlet is for uber-experienced hikers and trail runners ONLY. You’ll need to be confident navigating off-trail, understand mountain weather hazards, and be able to move fast and light.

When is the Best Season for Hiking in Rocky Mountain National Park?

The best time of year to hike in Rocky Mountain National Park is from late June until October.

Keep in mind that July and early August are the monsoon season. This is when dangerous and life-threatening thunderstorms take over in the mountains.

Storms usually show up quickly and violently by noon so always check the weather before hitting the trail.

You can certainly enjoy Rocky Mountain National Park trails year-round, but keep in mind that many trails have avalanche hazards in the winter and Trail Ridge Road is completely closed. Beginner winter hikers should have an avalanche safety education before heading out.

Quick Tips for Visiting Rocky Mountain National Park

As a mountain hiking expert, I know a thing or two about hiking in the Rockies. Before hitting the trail, be sure to read my guide to hiking in Colorado. You’ll find loads of safety tips and information about what to expect in the alpine.

When it comes to making the most of Rocky Mountain National Park hikes, there are a few location-specific tips to keep in mind:

Check Road Conditions

Many of the roads close in the winter and trails can be inaccessible with snow. Always check with the ranger station for the latest conditions.

Purchase a Parks Pass and Plan in Advance

If you plan on visiting the park for multiple days, consider buying a parks pass, it might be cheaper and it will get you into a variety of national parks and monuments across the US.

Popular Parking Lots Fill Up Before Sunrise

Parking lots fill up super early in RMNP – especially for any trails at Glacier Gorge, Bear Lake, or Long’s Peak.

If you’re there after 8 am, plan on taking the bus to get around. You can snag the shuttle at the Park and Ride near the Glacier Basin Campground. Shuttle service is from 8 am to 5 pm.

Leave No Trace

As always, keep it better than you found it. Pack out your trash (even apple cores, TP, and orange peels), don’t harass or approach wildlife, stay on the trail.

Chase the Sunrise

Go for a sunrise hike. Sunrise is the absolute best time to go for a hike in Rocky Mountain NP. The most crowded trails in Rocky Mountain fill up very quickly. If you want any chance at solitude or a quiet trail, plan on putting on that headlamp and starting before the sun rises!

Local Tip: Most people hike at about 30 minutes per mile or 1 hour per 1,000 foot of gain. If you want to be at your hiking destination by sunrise, use the stats on the above hikes to plan accordingly!

Pack a Picnic!

Bring a packed lunch. If you plan on being in the park all day, food is limited. Heading out of the park and back in again will invalidate your time slot, so to make the most of one day in Rocky Mountian National Park, pack a cooler filled with snacks, lunch items, and plenty of water.

Acclimatize Properly

If you’re coming from lower elevations, you may struggle a bit with the change in altitude. Plan a down day for your first day in Colorado. Drink plenty of water and tackle an easy, mellow hike to get used to the altitude. Eating foods that are rich in garlic can help you get used to the high altitude. Avoid alcohol and caffeine for faster acclimatizing.

Watch the Weather

The Colorado weather – particularly in the mountains – can be wild, unpredictable, and dangerous. The summer monsoons bring quick and violent thunderstorms to the mountains. These storms kill hikers every year who are unprepared. Rocky Mountain National Park has a higher number of deaths from lightning strikes because so many people flock to the park.

Plan your hike to avoid thunderstorms by using a tool like weather.gov to check the exact trail, lake, or landmark you’re heading to. Aim to be below treeline (the highest elevation that trees grow) before 11 am to avoid storms. Never hike above treeline in a thunderstorm.

Never Approach or Feed Wildlife

Many different animals call Rocky Mountain National Park home. From bears to elk and even moose there are plenty of creatures who wander the trails. Your best chance at spotting wildlife is actually early in the morning before the throngs of people scare the animals from the trail.

Never approach wildlife. In general, you want to keep at least 100 yards of distance between you and an animal. Elk and moose charge tourists every year in Estes Park.

Don’t feed small critters like chipmunks, marmot, and pika. Your food is not a natural part of their diet. When you feed these animals you do a lot of harm to their digestive tract. Not to mention, you encourage them to be bold and chew through your hiking pack.

Use Trailhead Toilets or Pack Out Your Toilet Paper

Toilet paper and human waste is a huge problem in Rocky Mountain National Park. Always use toilets at trailheads when possible. But if you do have to go on the trail, be sure to be 70 adult steps away from the trail or any water source. Bury your business in a 6-inch cathole. Then pack out your used toilet paper. Animals dig it up and it’s unsightly at the trail.

Leave Fido at Home

Rocky Mountain National Park is not dog-friendly. In fact, your dog cannot leave the pavement, meaning they are pretty much confined to the car. In the summer, mountain temps can get quite hot and give your dog heat stroke. Just leave your pup at home if you plan on hiking in Rocky Mountain National Park.

Even though Rocky Mountain National Park hikes can be quite popular, if something were to go wrong, rescue services can take hours to reach you. Here’s what you’ll need to bring for your Rocky Mountain National Park Hike.

What is the Best Hike in Rocky Mountain National Park?

When it comes to the best hike in Rocky Mountain National Park, there is no one single answer. It largely depends on what you’d like to see and how challenging you’d like your hike to be.

Emerald Lake is the best hike in Rocky Mountain National Park for water lovers. You’ll pass three distinct lakes along the way. For more of a challenge check out Sky Pond or Chasm Lake.

For those that want a bird’s eye view, Hallet Peak is an excellent choice. This challenging butt-buster doesn’t require any special skills, but will certainly challenge your legs and lungs!

If you have plenty of mountain hiking experience, know how to scramble (low-grade rock climb without ropes), and aren’t afraid of butt-puckering exposure, then the Keyhole Route on Long’s Peak is right for you.

What is the Hardest Hike in Colorado?

There are several immensely challenging hikes in Colorado and you can find a few of them in Rocky Mountain National Park. Many people argue that Long’s Peak Keyhole Route is the toughest hike in Colorado, however, to call this trail a hike is a bit of a misnomer. You need expert mountain hiking experience, rock scrambling abilities (meaning you’ll be using your hands climbing up over exposed rocks), and a helmet to make this journey.

Another hot contender is the Colorado Trail – at over 486 miles it takes about a month to complete, making it the longest hike in Colorado. It’s also one of the highest elevation thru-hikes in the country.
