This hike will be Flattop Mountain in Rocky Mountain National Park that begins at the Bear Lake Trailhead. While getting ready for Scott's hike to Flattop Mtn in the Trap Park area off Cameron Pass, I though why not list a second hike to the 'other' Flattop Mountain in RMNP.  So here it we go! 

I’ve been asked ‘What about Hallett?’. I thought the same when I posted this trip. My plans were hike Flattop and if the weather and if the strength of the group allowed, we would also summit Hallet. Soooo, I’m updating the trip to include Hallett to the hike. It all will depend on the weather and the strength of the group. Adding Hallet will add 1.5 miles and about 400 ft elevation gain to the trip.

Any questions, advise or in need of further information, please contact Bill Trout at Also I'm allowing participants to sign up for the hike themselves. However, if I haven't hiked with you, I will contact you for information about recent hikes you have done inorder to determine your ability to complete this hike. Nothing personal, but I do want to ensure we have a safe and fun day in the mountains for everyone!



From the Bear Lake trailhead we will hike around the eastern shore of Bear Lake to the Fern Lake trail. We will continue on the Fern Lake trail heading west. As the trail climbs we will enjoy spectacular views of Longs Peak, Keyboard of the Winds, Pagoda and Chiefs Head peaks. After hiking about a mile, we will take the Flattop Mountain Trail and begin the ascent of the eastern flank of the Flattop Mountain. Once on the Flattop Mountain trail the climb becomes steeper for much of the remainder of the route. At roughly 1.7 miles from the trailhead, at an elevation of 10,480 feet, we will reach the Dream Lake Overlook where we will have a great view of Longs Peak. At roughly 2.5 miles, we will emerge from treeline and have panoramic views of the surrounding area. At about 3 miles, we will reach the Emerald Lake Overlook and have another opportunity for some outstanding views. As we continue to proceed to the summit the slope begins to lessen for the final 2/3 mile to the top. It can be difficult to determine the summit, but the junction with the North Inlet Trail and Tonahutu Creek Trail is usually recognized as the summit of Flattop Mountain. The views from the summit can be outstanding. Towards the south is 12,713 foot Hallet Peak, towards the north is 12,129 foot Notchtop Mountain and the Mummy Range, and looking towards the northwest is 12,363 foot Ptarmigan Point and the Never Summer Range.




Since this hike will be in early October, the weather could be beautiful to blustery. So bring wind protection, rain and possible snow protection and some warm clothing; hat, gloves, insulating layer, etc.  I would also recomend 2 liters of water, food and snacks. I may also throw in microspikes just in case.

Since I'm not sure about parking situation at Bear Lake, I would like to meet at NW corner of the Target parking lot at College and Troutman at 6 am and leave promptly at 6:15. Hopefully, that will get us parking at Bear Lake and ahead of the potential crowds. If I've forgotten to mention anything or have any questions, let me know. Also if anyone would like to co-lead this hike let me know. It's been awhile since I've hiked Flattop Mtn, so I would appreciate any recent updates.


Sorry it is past the registration deadline for this event.
