Mecca of Classic Routes

Boulder, Colorado is home to many fantastic rock climbing venues, including the famous Eldorado Canyon and the well-recognized Flatirons. These are excellent rock climbing areas to both learn and hone your skill as a climber. They offer you the opportunity to do anything from climb a classic route, perfect your rock climbing technique, or learn valuable technical skills.

Eldorado Canyon

Eldorado Canyon State Park represents one of our country’s finest and most famous climbing areas. Many of the conglomerate sandstone walls soar to over 700′ high, and offer a wealth of both single and multi-pitch routes of all difficulties. The conglomerate sandstone rock quality is second to none, and is more reminiscent of granite than other sandstone climbing destinations. The Redgarden Wall is host to a wide variety of climbing routes including many “must-dos” including The Yellow SpurRuper, and Rewritten to name a few.

The Bastille and Wind Tower also offer classic climbs, both single and multi-pitch. This is a great venue to improve your climbing skill, and also offers easy logistics for setting up top ropes for technical training and more.

The Flatirons

The Flatirons form the classic backdrop and scenery of Boulder and are easily recognizable when you arrive to the area. The First and Third Flatirons offer some of the best climbing as well as some moderate multi-pitch climbing to the top of their features. The Direct East Face of the First Flatiron is one of the longer routes of the area and provides stunning positions and scenery of the surrounding area.

Other can’t miss climbs in the Flatirons include the Standard East Face of the 3rd Flatiron, and the North Arete of the First Flatiron. Overall, these climbs represent an excellent way to become more familiar with multi-pitch climbing techniques in a user friendly setting.

Rock Climbing Equipment List

BackpackDescriptionGuide's Pick
The Osprey Mutant 38 represents an excellent all around performer for Ice Climbing trips in the Ouray Ice Park and surrounding San Juan backcountry.
Water BottlesDescriptionGuide's Pick
We recommend wide mouth Nalgene (or similar) water bottles for the majority of our programs. Two 1 liter bottles is the standard for days in the mountains.
Personal FoodDescriptionGuide's Pick
Lunch begins when breakfast ends and ends when dinner begins. Bring what you like to eat and consider the length, relative difficulty, weight, and other factors when deciding what to bring in the mountains with you. A variety is always best. Don't be afraid of Mr. T.
SunscreenDescriptionGuide's Pick
Essential for all of our programs. SPF 30 would be our minimum recommendation. Typically a 4 oz. bottle will suffice but consider trip length when deciding how much to pack.
Belay DeviceDescriptionGuide's Pick
A belay device is a required item on any of our technical climbing or mountaineering courses. While not necessary to have the Guide ATC specifically, we think owning one of these offers additional versatility as you progress and gain additional knowledge about the various levels of functionality provided by a device of this type.
HarnessDescriptionGuide's Pick
The BD Aspect Harness is a great all around performer for all types of climbing - ice, rock, alpine etc. The adjustable leg loops and integrated ice clipper loops make this a solid investment as your do-all harness.
Locking CarabinersDescriptionGuide's Pick
We recommend at minimum 2 - 3 personal locking carabiners on our climbing courses and any technical private guided program. We prefer classic screw gate carabiners over other types of locking mechanisms.
Climbing HelmetDescriptionGuide's Pick
A versatile, hybrid-shell helmet for lightweight protection in any discipline, the Vector features excellent ventilation and a ratcheting adjuster.

Training & Follow Up Climbs

As always, being in excellent physical shape is an important component of our our programs. A good mixture of cardiovascular fitness, muscular fitness, and especially core strength will help you to maximize the potential rewards that are possible on a great climbing trip.

Specific to Rock Climbing – it is a great idea to experience rock climbing in a gym first prior to your first experience outside!

Before Your Trip

Familiarity with basic climbing principles such as knots, belaying, rappelling, and other climbing techniques can be very helpful for our Intro Course participants.  Though not required, prior gym climbing experience will help you to acquire and assimilate the information covered in our rock climbing course progression as quickly as possible.
