Technical Climbing School

The Colorado Mountain Club’s Technical Climbing School connects aspiring climbers with their vertical ambitions.

Classes and trips are designed to teach the technical elements of rock and snow climbing, including the use of ropes, anchors, ice tools, protection, crampons and specialized skills to safely negotiate challenging terrain. The class modules are ideal for individuals with goals such as leading fifth-class rock, ice climbing or ascending difficult peaks.

The entry-level courses provide a foundation, covering such topics as belaying, movement techniques, gear and navigation. More advanced courses build upon those basics and teach students everything they need to climb throughout Colorado. The modular approach to the curriculum allows students to select classes and dates that fit their schedule and specific interests. The classes can be taken individually or as packages to achieve certificates in Climbing, Basic Mountaineering and Intermediate Mountaineering.

The infographic below shows the recommended progression through CMC Technical Climbing School:

CMC Technical Schools Diagram of Course Progression

Alpine Climbing Certificate

Within the Technical Climbing School, you can take 6 of our 19 classes to earn a certificate in Alpine Climbing (Formerly Basic Mountaineering) Think of the Alpine Climbing School (ACS) as an academic/vocational degree within the Technical Climbing School.

You have two options when it comes to ACS

  • Modular Track: you simply look at the CMC calendar and select the class sessions that fit your calendar.
  • Team Track: allows you to work with the same small group of classmates through all the Alpine CLimbing classes. The traditional format is slightly less expensive (you pay for 5 classes but get 6), but the dates are more rigid. Team track is complete for 2019.  Details for next year will be posted in the fall.      

There are two sessions of Alpine Climbing School offered each year. In the CMC calendar, filter for classes and look for Alpine Climbing Certificate The two sessions will almost always be offered in Feb -May. When you click on the class the Event Details will give you all the dates for that session.

Basic Climbing

Basic Climbing is the best class to start with! It is a prerequisite for all the rock, snow and ice climbing classes (not required for navigation courses). Upon completion of this class you’ll be able to climb indoors at any rock climbing gym. You’ll learn:

  • How to use climbing helmet, harness, belay device, safety leash
  • How to tie in to the rope using a Figure Eight Retrace
  • How to tie an Overhand Knot, Clove Hitch, Girth Hitch
  • How to top rope belay using Pull-Brake-Under-Slide method
  • How to use climbing commands
  • How to coil a climbing rope

Modular Track, Session D - September 2019


Intermediate Rock Climbing

Building off of Basic Climbing,intermediate focuses on climbing safety: equipment (and using it properly), communication, belaying, lowering, and rappelling.

You’ll learn:

  • How to use hands and feet efficiently on rock
  • Experience climbing outside
  • How to tie a Double Fisherman, Water Knot, Muenter Hitch, Figure Eight On a Bight, Autoblock Hitch
  • Multiple methods of rappel
  • Rappel back-ups

Modular Track, Session D - September 2019


Navigation Level 1
Navigation courses have no prerequisites and can also be a good place to start taking TCS classes.

 You’ll learn:

  • How to procure & read topographic maps
  • How to measure a bearing on the map
  • How to plot a bearing on the map
  • How to take a bearing in the field and follow it

Modular Track, Session C - October 2019

Navigation Level 2
Level 2 allows you to build off of your Level 1 navigation skills and apply them in an intensive field application and extension of material taught in Navigation Level 1.

You’ll learn:

  • How to match terrain to the map
  • How to travel from point to point using map and compass together
  • How to follow a bearing in zero visibility
  • How to navigate around obstacles
  • How to measure slope angles

Modular Track, Session C - October 2019

Intermediate Snow 

Snow is the third portion of classes required to achieve your BMS certificate. Successful completion of Basic Climbing a prerequisite to enrolling in Basic Snow.

You’ll learn:

  • How to use crampons and ice axe
  • How to move over snow
  • How to self arrest

Advanced Snow 

This class covers technical skills you need to climb a snow couloir.

You’ll learn:

  • How to build snow anchors
  • How to tie an Alpine Butterfly
  • How to travel as a roped team
  • How to use snow protection


Intermediate Alpine Climbing Certificate

Building off of the skills you learned for ACS, branch out into Ice climbing, learn how to escape a belay, rappel past an obstruction, and perform a self rescue. All Intermediate Mountaineering courses are dependent on your successful completion of the Basic ACS courses. Just like with those courses, there is no specific order you need to take these classes in as long as you have all the necessary prerequisites. There is no traditional path for Intermediate Mountaineering, all classes are taken as individual modules.

Basic Anchors

Prerequisite of intermediate rock climbing required. Students will learn to build top rope climbing anchors using natural features and fixed protection.

You’ll learn:

  • How to evaluate natural features (trees, boulders, rock horns, etc) and fixed protection (bolts).
  • How to build anchors suitable for top-roping and rappelling.
  • How to incoporate methods for additional security while working in a cliff-top environment.

Session B - July


Climbing Self Rescue 1

Building off of skills learned in intermediate rock climbing, this course will prepare students to deal with problems they may encounter during a multi-pitch climb. Functions as a partial prerequisite to self rescue level 2.

You’ll learn:

  • How to tie a Prusik Hitch, Bachmann Hitch, Klemheist, Mule Knot
  • How to escape a loaded belay
  • How to ascend a rope
  • How to rappel past an obstruction in the rope


Rock Seconding

This course also builds off the skills learned in intermediate rock climbing and teaches students:

  • Belaying a lead climber
