The Drive from Denver

The drive from the center of Denver takes about 2 hours. The most direct route is through Boulder, Lyons, Estes Park and then on to the trail head in the Rocky Mountain National Park (RMNP). Another beautiful drive is to go a little farther out-of-the-way up I-25, through Loveland, Estes Park and then on to RMNP. This route ads about 15 to 20 minutes to the drive but it is less traveled and you get to drive through some beautiful canyons west of Loveland and the road follows a gorgeous river all the way into Estes Park.

Driving Tip: The route through Loveland can actually be faster during the summer months as most tourists travel through Lyons to Estes Park.

My daughter, Grace, and I woke up at 3:30am and hit the road by 4:30 so we could get to the trailhead by sunrise. We started our drive from the south side of Denver near Englewood.

I have learned the best times to get out in Colorado is early. The weather is usually nicer in the mornings, the traffic is lighter and getting to the trailhead before the crowds get there is especially nice.

We had a great drive up through Loveland, Colorado. We had never taken this route before and we wanted to see if this way was better or prettier than driving through Lyons. I can’t say it’s better but it is just as nice and it is a better route when you know the traffic will be heavy.

Our Day on the Trail

Longs Peak in the Rocky Mountain National ParkGetting to the RMNP early is great as we missed a lot of traffic, plus, if you arrive early, the park entrance gates are open and there is no one there to ask for money. I’m not about cheating the park service, and we didn’t, as we have an annual National Parks pass, but I thought I would give you a little money saving tip. Another tip is, pay for the National Park pass, which is only about $80 and the one-day pass to the RMNP is around $40. You’re not paying much more and if you visit more than once then you have paid for the annual pass. Only pay the $40 if you know this will be the only national park you will visit this year.

We arrived at the trailhead around 6:30am. The sun was just coming up over the eastern horizon and the parking lot was only a quarter full or less. The facilities are first-rate and there was a park ranger there to greet us. It was an absolutely stunning day as you can see from one of our first photos on the trail.

The trail is extremely well maintained and it is a popular trail. This trail takes you to Flattop Mountain but then on to Hallet Peak if you want to continue on.

The climb was steep in parts but definitely manageable for Grace and me. We were over 10,000 feet in elevation pretty quick so make sure you’re ready for the altitude and drink a lot of water.SPOT Gen3 Satellite Messenger

I almost forgot to mention that this is the hike where Grace and I saw the hiker that had the emergency satellite messenger strapped to his backpack. I stopped and asked him what it was and that’s when he told me what it was.

He said that he hikes a lot by himself and having it lets his wife know where he is and he can always send a message if he needs help. It gives his family peace of mind knowing that he is really never alone and can always call for help.

If you would like to know more about this satellite messenger, you can see more about it her at my SPOT Gen3 Review.

The scenery was great for our entire hike and we always had great views of Longs Peak.

I have to admit that this was the highest point we reached as I had to be back for a meeting in Denver by 1:30pm. We spent a little over four hours on the trail and were close to Flattop Mountain. We will have to go back another day to finish it and continue on to Hallets Peak.

This goes to show you that you can have a great hike in the Rockies and be back home by 1pm if you get up early enough.

On the way back down the trail we passed at least 40 hikers heading up the trail. Everyone was really nice and even though it was a busy trail, it was still enjoyable.

We had a chance to stop at Bear Lake near the trailhead and take in the beautiful scenery.

As you can see, this would be a great lake to get some great photos and relax for a while. It looks like there are 20 or more lakes in this area, plus waterfalls, so you could go back to this one area for years and still not see everything it has to offer.

Trail Recommendations

Grace and I love this area and this trail. My son, Caleb, and daughter, Grace have been here many times over the years as they have gone to the week-long camp at Ravencrest, just southeast of Estes Park. Ravencrest Chalet

Another one of Caleb and Grace’s favorite things to do is to head into Estes Park and enjoy some shopping, which they never want to do with their parents, and also have a great time on Estes lake in Estes Park.

This was an incredible hike. The entire area from the drive to the Rocky Mountain National Park (RMNP) and Estes Park is a great place to come and enjoy for everyone.

  1. It has always been on my bucket list to take the Colorado flattop mountain hike but work has never truly permitted me. Maybe in the coming days during my work leave, I would be able to finally explore this place. Thanks so much for this post though and the tips you shared especially about going early and still getting back to resume our daily tasks. Thanks for this and I’d surely plan this with a friend to make it more fun.

    • Try to add a little time to check out some of the great shops in Estes Park and have a nice lunch. My son’s favorite thing to do there is to have an elk burger.


  2. 10,000 feet is up there! I’ve driven over the Rocky Mountains twice, and both times it was snowing heavily, so it was a little bit hairy, but not as bad as I thought it was going to be. Flattop Mountain Trail is a nice little drive from Denver. I really like Boulder, so it was be a nice stop along the way. Great advice getting out to the trailhead early, and thanks for the pricing information and advice. Those photos that you took are amazing. It’s good to know that there are around 20 different lakes as well as waterfalls. This looks like an excellent hiking trail and I will definitely check it out next time I am in Colorado, well done!

    • Taking some time in Boulder as well as Estes Park would be a great addition to hiking in the Rocky Mountain National Park. Enjoy your trip when you get there and let us know how it went.


  3. Wow! This is awesome to read about the Colorado flattop mountain hiking trails. This is great and excellent piece of information and it is also a guide because it has given tips on how best to reach the place and exactly the things to do to ensure that we enjoy the moments spent at the park. Getting to explore nature from the mountain top is one thing I have never done and would be thrilled to explore the possibilities of engaging in that. This is cool to me and to know of in general. Great one

    • You are very welcome. There is a reason this area is the most visited part of the park. It is absolutely gorgeous and has a lot to offer.

      let me know if you make plans to visit there and stop back by to let us know how it went.
