Mt. Tileston is a small summit. It is not an overtly high mountain nor does it carry much prominence as a separate peak. Fact, Mt. Tileston can only claim 314ft. of prominence barely making it a ranked mountain. It comes in at #69 on the peak list for Rocky Mountain National Park according to Roach. One could easily mistake this small peak as nothing more than a high point along the northern Bighorn Mountain Ridge but due to it rising above the de facto 300ft, it carries it’s own distinction. Not to mention, it is also named on most USGS Quads and NPS maps, so, it too shall have its’ home here on Summitpost.
This narrow summit lies almost exactly two miles south of Mummy Mountain and 1.2 miles due north of Bighorn Mountain. One could practically draw a straight 90º line and connect all three summits including Point 11,080. The views of Mummy Mountain, especially from the summit of Mt. Tileston are among the best to be had in Rocky Mountain National Park. The rugged southwestern face of Mummy Mountain looks that much more imposing when viewed at similar elevation just across the valley. Mt. Tileston’s northern aspect melds into the confluence of the Roaring River Valley and the Black Canyon. This gentle slope is the predominant route up this small mountain and many people will tend to use Pott’s Puddle as their launching point up this easy mountain.
From Point 10,720Mt. Tileston is in the middleground.

Mt. Tileston was named thus as a tribute to the late Mrs. Stanley, Flora Jane Record Tileston, later Mrs. Stanley (1848-1939). She was born originally in Maine and eventually died in Estes Park. She was an active member of the community in Estes Park. She was known for her dressing as a gypsy and telling peoples fortunes as a fundraiser for the Estes Park Women’s club. In fact, her spirit is one of many thought to haunt the Stanley Hotel in Estes Park!

Getting There

The launching point for Mt. Tileston is the small town of Estes Park. This mountain town is also the entrance to the eastern side of Rocky Mountain National Park via Trail Ridge Road. To reach Estes Park, use the following directions:

Take I-25 north to exit #243. This is the exit for hwy. 66. It is roughly 22 miles or 30km north of Denver. Head west (left) towards the city of Longmont. Hwy. 66 just skirts the northern edge of Longmont. Continue west for an additional 5 miles to the small town of Lyons. Continue through Lyons, slowly (the police here are eager to hand out speeding tickets) following the signs for Estes Park. Continue west up St. Vrain Canyon for 20 or so miles until you reach Estes Park.

From I-25, in either direction coming north from Fort Collins or as an alternate route, south from Denver, take exit #257 and merge onto hwy. 34 heading west towards Loveland. From Greeley, simply stay on hwy. 34 into Loveland. As one approaches Loveland, hwy. 34 turns into Eisenhower Blvd. Continue west through Loveland as hwy. 34 progresses west into Big Thompson Canyon, a scenic drive onto itself. Estes Park is 21.7 miles west from Loveland through the serpentine canyon.

Once in the town of Estes Park, There are three choices of trailheads one can utilize for Mt. Tilston. These are Lawn Lake, Black Canyon and Cow Creek. The later two involve the greatest mileage but do not require an entrance fee into Rocky Mountain National Park since the entrance points for these two trails are via backcountry trails. Lawn Lake Trail is the shortest & most expedient of the three and probably the most scenic. The Fay Lakes, the Y-Couloir on Mt.Ypislon, Hourglass Couloir on Fairchild and the eastern aspect on Mt. Chiquita are also accessible from this trail.
Along the summit ridgeThe summit ridge is still in treeline!


1.) LAWN LAKE: This trailhead lies inside of Rocky Mountain National Park at 8,540ft. and involves roundtrip mileage of ~11 miles. This route involves the least hiking mileage of the three but invariably, the busiest of the three. This trail even sees a fair amount of traffic in the winter. Since it is located inside RMNP, the mandatory $20.00 is required. Leave Estes Park on hwy. 34 west for five miles to RMNP Fall River entrance. At the park boundary, hwy. 34 ends and the famous Trail Ridge Road begins. Continue up into the park for 2.6 miles to a “T” intersection. This is the turnoff for Old Fall River Road and it is signed. Turn right (west) and proceed for .1 mile. The trailhead is located off to the right a short distance. There are ample parking and restroom facilities available. As said, this is a popular trailhead, so other vehicles will likely be present.
Lawn Lake Trail starts roughly at the center of Horseshoe Park and climbs rather steadily with some steeper sections as it parallels the Roaring River to the immediate west. This trail is maintained and easy to follow, even in winter. After 1.6 miles, the trail junction for Ypislon Peak and Fay Lakes comes into access. After this junction, the trail will switchback frequently through dense forest with an occasional clearing down to the river below. Please keep in mind, since Mt. Tileston has no trails leading to it’s summit, off-piste trekking and bushwhacking will be involved.

* At the present (6.21.07), entrance fees to Rocky Mountain National Park are $20.00 per vehicle, good for seven consecutive days. Due to a measure from Washington and from the NPS, many national parks and monuments will be increasing entrance fees over the course of the next three years (calendar end date, 2009). This is due to the government cutting the amount of monies appropriated to national parks and historic sites (Department of the Interior). At this point, Park Administration has no plans to raise entrance fees or pass prices at least through 2007.



The trailhead is located 1.1 mile from a predominant intersection in Estes Park. Take Wonderview Avenue north past a Safeway shopping complex. It will gently curve to the west in front of the Stanley Hotel. Turn right (north) at Macgregor Avenue and follow north for the remaining .7 mile to the ranch. The road will bend sharply at this point and eventually turn into Devil's Gulch road. Continue straight on the rough dirt road and simply follow the signs to the TH where the road comes to an end. There are a couple of half-moon outhouses located at the trailhead and water. This is also the staging area for technical climbs up onto Lumpy Ridge.
From the small parking area located at Black Canyon TH, launch out towards the west, past the trailhead sign. The first .4-.6 miles of this trail pretty much just skirts the meadow and parallels Lumpy Ridge. As soon as the trail starts to climb up into Black Canyon, the shade will be a welcome relief as this area can get hot in the summer and water is scarce. The Black Canyon trail segment, from the TH to the junction with Dark Canyon on the west end of the saddle is only 1.6 miles; shorter then following Cow Creek.
I can't say which is more scenic because both have their pluses and minuses. However, Black Canyon TH would make for a more convenient and shorter day vs. Cow Creek. At the junction with the Dark Canyon Trail, Lawn Lake is an additional 5.4 miles west. Mt. Tileston's northern slope and Pott’s Puddle lie 5.2 miles west just past the two campgrounds: Lower Tileston and Tileston Meadows.
Bridel Veil Falls is 1.4 miles to the east.

3.) COW CREEK: From the town of Estes Park (central intersection), drive north on Macgregor Avenue as it swings westward past the Stanley Hotel to Devils Gulch Road. This is also Larimer County 43. Turn right onto CR 43. Follow this road north. At 1.7 miles from Estes Park, you'll pass a small parking area for Gem Lake on the left. At 3.4 miles, the road will turn gently to the right. At this bend, the road will continue straight to McGraw Ranch. Follow this dirt road as it weaves through private land for an additional 2.1 miles to its terminus at the McGraw Ranch and Cow Creek trailhead.
There is enough room at the TH proper for 3-4 vehicles. Because of gradual increased use of this area, additional parking has been implemented along the road. There is no potable water at the TH, however there are restroom facilities and an emergency phone.

Cow Creek Trail starts out as an access road bisecting the McGraw Ranch eventually diminishing to a double-breasted wagon track and finally to a single track. The lower portion of this trail is easy and straightforward. It follows Cow Creek through the meadow passing a few campsites and rock formations such as, "The Pear" and "The Book" along the way until the Bridal Veil spur is reached after 2.1 miles. Continue straight towards Lawn Lake. This second half is the Dark Canyon portion. The meadow will eventually disappear and the canyon will narrow. The trail continues to weave up the canyon through ever-denser forest with occasional switchbacks until it tops out at a saddle in between Dark Mountain, Sundance Buttress and Macgregor Mountain. The saddle is 3.5 miles from the Cow Creek trailhead. The trail junction for Black Canyon is .1-.2 mile down the other side of this gentle saddle where the trail continues on towards Lawn Lake and Stormy Peaks. Coming from this direction, that is, from the east vs. from the south as in the case of Lawn Lake, will involve considerable more mileage and time commitment however; this option affords one more scenery in lesser-visited areas of Rocky Mountain Park. Once you leave the Dark Canyon junction, travel west towards Lawn Lake for 2.2 miles. At this point, Mt. Tileston’s lower northern slopes and Pott’s Puddle will be quite noticeable.
