Chicago Basin 14’ers

Chicago Basin 14’ers

Sunlight, Windom, & Eolus Peaks

Chicago Basin

The Chicago Basin 14’ers are some of Colorado’s most aesthetic and scenic 14’ers. Sunlight Peak (14,059 ft.), Mt. Eolus (14,083 ft.), and Windom Peak (14,082 ft.) dominate the skyline scenery, though the basin is host to a number of other worthy climbs.  The area is unmatched for it’s wilderness setting, well maintained trails, and relatively easy access.  For those who would like to experience the essence of the San Juans and climb a few 14’ers along the way, then this is the trip for you.

Many of our trip participants are also on the Colorado 14’er quest, attempting to become one of the few people who have had the chance to stand on top of all of Colorado’s 54 highest peaks. There’s no question that for both first timers and seasoned Colorado climbers, Chicago Basin will be the highlight of your 14’ers endeavor and represents a great opportunity to climb 3 of the 54 14’ers in one amazing trip.

Friday – Sunday or Monday – Wednesday

For 2018 we have decided to offer two itinerary options. Friday through Sunday itineraries give you the opportunity to maximize the convenience of your travel schedule so that you can fit in other great trips on your travels, or perhaps make it back to the board room in time for that big meeting!  Monday through Wednesday itineraries typically provide a slightly quieter experience in Chicago Basin and take advantage of the fact that in summer, your travel plans or work schedule might be a bit more relaxed and flexible. Either way, we offer plenty of fixed date trip options to get you out into Colorado’s finest wilderness area!

Wilderness Access via the D&SNGRR

By virture of the Durango – Silverton Narrow Guage Railroad (D&SNGRR), we can limit the length of our approach to Chicago Basin to a mere 6 miles.  A relic of the mining trade of the 1880’s – 1930’s, the train is world famous as it is one of the few narrow gauge railroads left in existence. This unique experience adds an interesting start and finish to this trip.  We take care of all the details, so that you can focus on admiring the beauty of Chicago Basin, and the climbs to the top of the 14’ers found within. You don’t have to be an expert mountaineer to take part in this incredible adventure – we’ve reached the summits of these peaks with 7 – 70 year olds!

Have been to Chicago Basin with SJMG twice. Could not have been happier with both guides. You run a great program and your guides really do represent SJMG well! – Bob A. Chicago Basin 14’ers 2015

Chicago Basin 14’ers Trip Itinerary

Chicago Basin

Day 1

In the morning we’ll board the D&SNGRR train in Durango for the ride to Needleton and the start of the hike/approach into Chicago Basin.  After approximately 6 miles we reach our camp at treeline in upper Chicago Basin.  Camp out.

Day 2

Rising early to avoid afternoon thunderstorms, we’ll approach the West Ridge of Sunlight Peak, an exposed ridge with a good mixture of 3rd and 4th class climbing all the way to the summit!  An alternate option for the ascent will be the Standard Route up the South Slopes of Sunlight Peak. Route choice on this peak will depend on a variety of factors and is up to the discretion of our guides and guest(s) for the trip.  Descending the south slopes, we’ll cross the upper Twin Lakes basin and head up to the summit of Windom Peak via the West Ridge and a series of 3rd class ledges.  We’ll be back at camp around 1 pm, where some relaxation and even a nap can ensue!  Camp out.

Durango Train

Day 3

Waking early again, we’ll approach the East Ridge of Mt. Eolus which is characterized by mixed 3rd and 4th class climbing – and the classic “Cat Walk” Traverse.  After our successful summit, we’ll head back to camp, pack things up, and head back down to the trail head where the train will meet us for a 3:45 pm pick up.  The train will have us back to Durango at approximately 6:15 pm – plenty of time to catch a shower and enjoy a celebratory dinner!   Stay in a hotel or depart.  We have showers available at our office for those participants that have a arranged to depart directly after the end of the trip.

Itinerary Note

The majority of the time spent on the Chicago Basin 14’ers trip is at or above 10,000 ‘ in elevation.  If you live at sea level, it may be best to arrive in Durango a day earlier to allow for an easier adjustment to the altitude and thus a greater chance for success on the climbs.

1Before Your Trip

Upper Twin Lakes

The Chicago Basin 14’ers trip is a strenuous trip conducted at altitudes above 10,000 feet.  Therefore, previous experience hiking in the mountains and/or multi-day backpacking experience will be very helpful to you on this program.  Though the actual climbing level required for this trip is not difficult, the best training regimen would include a mixture of cardiovascular fitness training (running, biking, hiking etc.), and muscular/core fitness exercises.  The addition of some Yoga/stretching exercises will help to insure that you maintain good muscular flexibility as well.

For the Chicago Basin 14’ers you should be ready for:

  • Hiking approximately 6-7 miles per day with up to a 40 lb pack at altitudes between 8,000′ – 11,000 ‘
  • 8 – 10 hour summit days with a lighter “day pack”
  • Wilderness living
