_5th-12th grades______


Spend 6 to 12 days in the Colorado backcountry with other teens!

Registration for summer 2024 is now open

Our offsite, camping-based Adventures are focused on the development of outdoor skills and leadership while exploring Colorado’s stunning parks, monuments, and most scenic natural environments by foot, on rope, or watercraft.

Students on this expedition should expect to wake up early, carry a heavy backpack, step out of their comfort zone, and support each other through physical and mental challenges.

New Admissions Process

In 2024, we want to improve the quality of each participant’s experience in our Adventure programs. To do this, we will be implementing a more comprehensive admission process to ensure that each participant is placed in a program that is the best fit for that individual. Below are the steps for this process. 

See full admissions process
  1. Families will enroll in their preferred programs
  2. Families will receive an automatic confirmation email to show that they have been placed in their intended session.
  3. Families will receive a form that is required to be completed by the participant via email.
    1. This form must be completed to ensure enrollment in the program
    2. Failure to complete the form within the designated deadline will result in unenrollment from the program. 
  4. Once the form is complete, the family will receive an email to schedule a phone call with a KSS staff member.
  5. A KSS staff member will call the family. In this conversation the family has an opportunity to learn more about the program and for KSS to learn more about the participant and support them on their session(s). This conversation will help ensure that participants are enrolled in the most appropriate programming for the individual.

“My kid looks forward to this every year! It is so important for her to get out of her usual routine and meet new people and get a chance to be on her own.”

Justice, Equity, Diversity & Inclusion

Keystone Science School has the power to effect change in outdoor education. We know the trail won’t be easy, yet we remain resolute in our responsibility to press forward and help make the outdoors more just, equitable, diverse, and inclusive. With each step we take, we learn from existing footprints and create new ones where there are none. If you’re looking for Keystone Science School, you’ll know where to find us–on the trail.

Leadership Framework

Our Leadership Framework has a foundation of 5 main elements. As students progress through Adventures, they will become familiar with the 5 elements and have opportunities to grow within each. This framework is meant to help instructors identify which elements of leadership are linked to the activities and programs they are leading and how to effectively teach valuable skills through activity facilitation, debrief, and conversation.
