From Steamboat Springs Rock Guide: "The Domes are what might be called an alpine climbing oasis. Tucked away within Routt National Forest, They're a group of rock giants that emerge from the evergreens and form discreet canyon walls to the creek below. The climbs range from one to five pitches or more, depending on your ambition and creativity, with a vertical gain of up to 350 feet."
A very important thing to know is that this area is closed most of the year (at least until mid-summer) due to Falcon and Eagle nesting on the Domes. Please contact the Forest Service for this information before heading up.
From SSRG: "From Steamboat Springs, take US 40 east, to Rabbit Ears Pass. Look for Forest Service Road 100 [(aka Buffalo Park Rd. or CR-19)] to Buffalo Park. Turn right and follow FS-100 for [exactly] 10 miles. There is room to park on both sides of the road... watch your mileage, because it's not immediately obvious. If you reach Buffalo Park, you've gone too far.
The trail to the Domes is about a 1.5 mile hike, marked by survey tape, and crosses two meadows which are usually soggy; your feet may get wet. Beware of fallen logs and land sharks.... Camping spots are abundant along NF-100... There are six domes with established routes on them. They are: The Dome, Elephant Foot Buttress, Rotten Rock, Bimini Buttress, Parker House Dome, and Glob Rock"
The trailhead isn't at all obvious, so watch once you're exactly 10 miles in pull over and look for a trail on the right.
Regarding the falcon closure: The closed area only goes as far as a 1/4 mile radius around the dome, leaving many of the formations down valley technically open. The established trail goes through this closure, so it's best to use your topo map and devise an alternate approach. Also, at the trailhead, park on the left (east) side of the road. I know it says there is room to park on both sides, but there is plenty of room on the left and not much on the right, parking on both sides would only interefere with traffic.
At exactly 10 miles, you approach a rise. Park on either side of the road at the high point, lots more room on the right. Don't drive down the hill. Walk about 100 yards down the hill continuing in the direction you would have been driving and locate the trail on the right. No cairn, no tape.
Note: tight = passenger side as you approach from US Hwy 40.
Make your way around and over the fallen trees until you find the closure sign, then go to have a beer, two or more at Mahogany then hit Strawberry Hot Springs.
