    Our visit to Rocky Mountain National Park was very fluid - we didn't have much planned, but Alpine…read moreRidge Trail was still one of the only hikes that was on our must-do hike. It is so breath-takingly gorgeous, that if you're able to complete it, it should 100% be included on your itinerary. Located right by the Alpine Visitors Center, this hike is about 0.6 miles roundtrip and requires you to climb approximately 225 stairs. The hike itself is moderate, but also take into account that you're at a higher elevation - you'll probably have to take more frequent breaks, so just make sure to pace yourself. Plenty of fun placards to read along the way, though, so it's like the hike is inviting you to take a breather. The summit is at 12,005 feet and so beautiful. You will get a full 360 view from the top - take some time to just sit and enjoy. There's even a elevation sign at the top that you can take your picture with. It was June when we visited, so it was still cold, windy, and drizzling. Snow was still out on the mountains. But it was still so serene. The hike starts at the Alpine Visitors Center, which has both clean & modern bathrooms and a water bottle refill station. So make sure you stop by - it's not often you find both of these at a trailhead. Wonderful experience, highly recommend.

    If you're stopping at the Alpine Visitor Center when driving through Trail Ridge Road, it only…read moremakes sense to stop by here and go up the 1 mile hike. It is a slight bit challenging (well maybe it's because I didn't bring my water with me), but taking a break or so every 10 or so stairs will help out a ton. Once you get to the top, the views are priceless. You're not going to see viewpoints like this anywhere in RMNP. Being 12,000+ feet above sea level is special. This is one trail you can't skip out on and you'll remember it forever.

    The last of the lakes on this trail, this is definitely not the least. Actually, I'm not sure I…read morecould even identify the lake that would be considered the "least" since they're all so beautiful. All of the lakes (Emerald, Dream, Nymph, and Bear) have their own unique charm, which is what makes this trail so amazing! I think basically everyone rests here when they make it since it's essentially all the way uphill to get to this point. There's not a lot of room at the lakeshore as it's full of boulders, but everyone settled in their spots no issues. As always, make sure that you have appropriate hiking footwear, a hat, plenty of water, and some snacks. There are no toilets at this lake, so also make sure you use the washroom at the trailhead. Pace yourself on this hike since the air is thinner due to elevation.

    Our goal was to hike to Emerald Lake, and let me tell you... It was 100% worth it. On this 3.6 mile…read moreroundtrip hike, you'll also encounter Nymph Lake and Dream Lake. While they're both beautiful in their own right, neither one of them compare to the sheer beauty of Emerald Lake with the snowy mountains as a backdrop. As I said, it is a moderate hike. We started around 930am - would've been nicer to start earlier, but it still beat the full heat of the noon sun. There will be intermittent shade, but make sure you bring a hat, sunscreen, and plenty of water. We visited in mid June. Once we neared Dream Lake, we started encountering snow on the ground. I used hiking sandals, and I was able to do it in those - just be careful. That being said, with the amount of snow that was on the trail to Lake Haiyaha was completely un-doable in my shoes. Once you reach Emerald Lake, find a place to sit and just take it all in. I could've sat there all afternoon, just being at peace with nature. Absolutely gorgeous. To get to Emerald Lake, you'll need access to Bear Lake Road. Just be aware that Bear Lake Road requires a reservation SEPARATE from the reservation to the national park. There's a big lot at the trailhead, but it gets filled up. They do have a park & ride a few miles away with plenty of shuttles ready to bring you in. If you're able to make the hike, hiking to Emerald Lake is wonderful. The hike itself is gorgeous, and the final lake is beautiful. Plan it in your schedule, and you will not be disappointed.

Seriously, millions of visitors enjoy the park every year. I stayed in the gateway town of Estes Park, which is literally minutes away from the park entrance. I did the Nymph, Dream, Emerald, and Haiyaha Lakes via Nymph Lake Trail, as well as Bear Lake. The trails were in great condition, and even though the trails were heavily trafficked, everyone was pretty courteous. The views were simply amazing. Do note that you might need to be acclimated to the higher atmosphere (=thinner air) and so hiking may be more difficult than your usual if you're coming from lower elevations. I visited during elk mating season, and while I did see elk in the park, I saw even more in the parks of Estes Park!

    Lived in denver for 17 years, traveled all over the world and this is my first trip to RMNP. Wow,…read morewhat was I thinking waiting so long. One of the Crown Jewels of the National Park Service, RMNP sits just outside of Estes Park and 90 minutes from Denver. We camped at Moraine Park and with that came a guaranteed timed entry and all access to the park. It was the perfect way to avoid booking entry to the park and separate booking for Bear Lake area. Our campsite had a phenomenal view on Long's Peak and was walking distance to Elk meadow. Every morning and evening we were front row to the bull elk bugling and enjoyed a great camping experience. We saw so much wildlife but the stand outs were, Moose. Elk. Deer. Coyotes. Fox. Marmot. Pika. Blue Jay. The park is a spectacular spotlight on the Rocky Mountains. We hiked from meadows to mountain tops and enjoyed many epic views and endless fresh air. Got caught in a big rain storm and watched a hiker find his missing keys!! Please note, elk meadow is restricted a bit during this time to let the elk mate. We watched a coupled disregard that and wander down to get wedding photos near the elk herd, wedding dress and all. Park security did not find that amusing. I'm sure those were very expensive wedding photos lol. So much to see and experience. Now I understand why every tourist coming to Colorado needs to see this park.

I opted to eat a light, quick breakfast, and hit the road early in the morning to beat out the crowds. That way, I could enjoy lunch back in town in Estes Park too. To help manage crowding, if you're planning a visit you might need a timed entry + bear lake road reservation depending on the season you're visiting. This is not something you want to do on the fly unless you want to risk not being able to visit. This stroll isn't very long and it gives amazing views of forests, mountain peaks, and of course Bear Lake. Continue on the trail to Nymph, Dream & Emerald Lakes. I would say that these hikes are definitely worth the effort!

It was absolutely beautiful, with the lake surrounded by dramatic mountain peaks and a peaceful alpine setting. We spotted adorable chipmunks and beautiful blue-feathered birds along the way, which made the experience even more memorable. The roughly half-mile walk around the lake was manageable with our baby in a stroller and was a wonderful family-friendly way to experience the park. A beautiful and easy-to-enjoy stop that I would definitely recommend when visiting Rocky Mountain National Park!

It's easy to reach in all seasons: due to the train tunnel, the dirt road to the trailhead is kept well maintained and plowed. Definitely way way more crowded on summer weekends than in winter. Several little waterfalls and tons on wildflowers even in late August made it a rewarding trail along the way, not only payoffs at the lakes. The trail from the lower two lakes to the upper lake is much steeper, but worth the added effort. Just note that when you first reach what you think is the upper lake, it's actually the drainage (albeit also lovely, see my attached photo); you need to go just a bit further over the boulders & through some bushes to reach the final upper cirque.

That and Indian peaks wilderness…read more Crater lakes is a moderate hike to 5 fantastic lakes that you can hike, camp, backpack, fish at. Last time I was there I saw two amazing Moose...just gorgeous. Area gets insane on the weekends with tons of peoples and dogs. Last three times I have been there I have been in thunder and hails storms after 1 pm. So if you are planning to hike getting off the mountain before might be a good idea. You can also take the more strenuous Heart Lake trail which is also fantastic and if you really want to kick your ass go up to Rogers pass for beautiful vistas. Great parking.
