Moraine Park: Campers, particularly hikers, favor this year-round campground, where several trails originate. It's easily accessed via Bear Lake Road, near the park's Beaver Meadows Entrance (southwest), and features 244 sites, all able to be reserved. It allows RVs up to 40 feet long and accommodates them further with a dump station and water hook-ups. Group sites also are available. 
Or enjoy a family wildflower hike to Gem Lake or Bridal Veil Falls. For a little more challenge, try the 2.8-mile Mills Lake trek. You’ll be rewarded with grand views of 14,259-foot-tall Longs Peak and the Keyboard of the Winds, a whimsical rock formation named for its shape. Pull over at Moraine Park for prime wildlife watching. More than 3,000 elk and 800 bighorn sheep live in the park, and this U-shaped valley is a regular gathering spot for bugling elk.

Region 5, known for waterfalls and backcountry, is south of Estes Park and contains Longs Peak—the park's iconic fourteener—and the Wild Basin area.[35] Other peaks and passes include Lily Mountain, Estes Cone, Twin Sisters, Boulder-Grand Pass, and Granite Pass.[47] Eugenia Mine operated about the late-19th to early-20th century, with some old equipment and a log cabin remaining.[47] Sites and trails include Boulder Field, Wild Basin Trail, and Homer Rouse Memorial Trail.[47]
Jess and I recently visited Colorado, which was my first visit to this wonderfully mountainous part of the US. We were primarily there to attend a travel influencers conference, but we tacked on a few days to do a bit of sight-seeing, starting off in the capital of Denver, where I watched my first ever baseball game, after which we headed out to explore some of those incredible mountains.

I would definitely recommend driving Trail Ridge Rd. between Grand Lake and Estes Park.  This is a great drive through the entire park with lots of great pull outs and stops along the way.  Be aware that this is the highest paved road on the continent at over 12,000ft. elevation and altitude sickness affects 50% of the visitors.  Trail Ridge Rd. is very scary to drive if you're not used to curvy roads with no guards rails.  Without stops, it will take 1.5hrs to drive from town to town.  Because we stopped so much, it took us 4 hrs to get from Estes Park to Grand Lake, we ate dinner in Grand Lake and then it took us 1.5 hrs to drive straight back.
Features: Take a quick hike around Lake Irene. Lake Irene is one of the highest lakes in the park; it’s just below the continental divide. This secluded little lake is surrounded by pine trees, and the trail is fairly flat along its entire length. However, once again, since this lake is at elevation, it can be a bit winding—you’ll notice that the trees don’t grow quite so high around the lake since you’ll be near tree line. Take note, the parking lot is the highest point on this hike, so be prepared for the uphill jaunt back to your car! Halfway through the trail, you can also visit an overlook on the trail that displays a vista of Lake Irene and a nearby meadow (this portion of the trail is not part of the length calculation above). It’s about an hour drive from the resort to the Lake Irene Picnic Area.

Lawn Lake Trail climbs to Lawn Lake and Crystal Lake, one of the parks deepest lakes, in the alpine ecosystem and along the course of the Roaring River. The river shows the massive damage caused by a dam failure in 1982 that claimed the lives of three campers. The trail is a strenuous snowshoe hike in the winter.[42] Ypsilon Lake Trail leads to its namesake as well as Chipmunk Lake, with views of Longs Peak, while traversing pine forests with grouseberry and bearberry bushes. The trail also offers views of the canyon gouged out by rampaging water that broke loose from Lawn Lake Dam in 1982. Visible is the south face of Ypsilon Mountain, with its Y shaped gash rising sharply from the shoreline.[42]
