Sage Expeditions

Welcome to Sage Expeditions, Sage International School’s outdoor program!  We offer opportunities for students in grades 3rd-12th grade, and hope to have more details in August so please check back about specific opportunities!


Sage Expeditions strives to be a positive cultural force at Sage International School.  We want to take students out of their comfort zones, to try something new (or master new skills), and to give them challenges they otherwise would not experience in the school atmosphere.  At the same time, we will push students to transfer their outdoor experiences back to their lives at home and in school, by reinforcing IB curriculum on every trip.  We will also teach natural and social histories of the places we travel and adventure, as well as teach and maintain a “leave no trace” ethic.

In the past, our expeditions have consisted of Friday day trips, overnight weekend trips (Thursday after school to Saturday afternoon), and longer “break” trips (Fall, Winter, and Spring).  Once a month, we have offered free, Friday service trips to nearby areas where we can help land managers enhance our natural southwest Idaho areas. When COVID hit we had to cancel all of our trips. Recently, we have been able to schedule a few outings and we look forward to future outings.

For every outing, enrollment will be based on a randomized lottery process, and not the first to register.  Hopefully, this allows all students to access the expeditions in a more equitable manner.  If a student is wait-listed for a trip, they will be given priority on the next trip they register for.  There will be a cutoff time to enter your student’s name for each trip.

Scholarships may be available for some trips. Please contact your outdoor expeditions coordinator for more details.

In the 2018-2019 school year, Sage Expeditions hosted 27% of our grade 3 through 12th students (202 unique students) who participated in 664 student days of adventure!  38 different teachers accompanied us!  And we gave out $1200 in scholarship money.  Finally, we led the following trips:

  • Day hiking

  • Scrambling and peak summits
  • Whitewater rafting
  • Rock climbing
  • Camping
  • Trail building
  • River clean-up
  • Rake-Up Boise
  • Alpine/Downhill skiing
  • Nordic skiing
  • Backcountry skiing
  • Mountaineering

Bogus Basin Life Sports Program 2023

Come and join us to take advantage of Bogus Basin’s fantastic “Life Sports” program. In this enrichment program offered through Sage, your child will complete a 1.5 hour group lesson, along with receiving a day lift ticket and equipment rental. After their lesson, they will have 2.5 hours of ski time to practice their skills.  Sage provides a ride from Sage to Bogus Basin and back, along with limited supervision (See prerequisites below).

Please don’t wait to reserve your child’s spot as this popular program fills up fast. Registration closes December 9th.

Days: Friday Dates: January 20th and January 27th

Grades: 3rd grade and up

Prerequisites:  Students have to be self-sufficient on the mountain.  During the free ski time, students must be able to get on and off the lifts with assistance only from the “lifties”, as well as be able to self-rescue on the hill (ie. get up off the snow and stand back up on their skis).  Students have to be mature enough to keep track of time and hold themselves to a schedule without direct supervision. Each day has four teacher chaperones, but with 36-48 total participants, chaperones cannot directly supervise all students at all times.

Times: Please meet at Sage at 7:55 each Friday to begin taking attendance at the bus.  We will depart promptly at 8:15 daily.  We plan to return to Sage at 4:15/4:30, but this time depends on traffic and students being timely on the mountain when it is time to leave.

Cost: $135 for 2 week session with Lessons and Rentals
$115 for 2 week session with Lessons Only

Unfortunately, there is no price discount if your student already has a season’s pass through Bogus.
