Help a young person in Colorado discover: "I can do more than I thought."
Young people need connection, belonging, and access to nature now more than ever. For many young people in Denver, cost, transportation, equipment, and a lack of welcoming opportunities can keep meaningful outdoor experiences out of reach.
Big City Mountaineers creates a way in. As the outdoor specialist within a broader youth development ecosystem, we partner with trusted youth-serving organizations to provide free, fully outfitted, professionally led outdoor programs for young people who face barriers to outdoor access.
Access is the vehicle. Youth development is the purpose. BCM facilitates transformative outdoor experiences that strengthen social-emotional wellbeing, deepen connection to nature, and foster positive youth development.
On a BCM program, a young person may hike a trail, paddle a lake, sleep beneath the stars, or step into leadership for the first time. Young people bring their own strengths, knowledge, and experiences. Skilled instructors, caring mentors, and community partners create a supportive setting where they can draw on those strengths, try hard things, build teamwork, and discover their own capabilities.
After meeting a challenge on the trail, one participant put it simply: "I didn't think I could do it, but I did." Another shared, "BCM was a place where I could just breathe."
Every mile hiked and every night outside builds toward what young people carry home: confidence, connection, and a growing relationship with nature. In BCM's 2025 evaluation, young people who completed expeditions scored higher than peers who had not participated in BCM programming:
* 36% higher self-efficacy
* 36% higher sense of belonging
* 28% higher self-esteem
Nationwide, 383 young people across five metropolitan areas - including Denver and Colorado Springs - have participated in BCM programs in 2026, joining a community of more than 10,000 young people served since 1989.
For more than 35 years, BCM has combined outdoor expertise, intentional programming, and trusted community partnerships. Our youth agency partners bring established relationships, continuity, and community knowledge before, during, and after each program. Together, we help confidence, connection, resilience, and leadership travel from the trail into young people's homes, schools, and communities.
Your gift creates access and opportunity that lasts.
Every BCM experience is free to participating young people. Your donation helps provide skilled instructors, caring mentors, transportation, food, safety systems, and essential outdoor gear.
* $85 helps make a day trip possible

Whatever amount you choose, your gift helps a young person feel welcomed, supported, and ready to discover what they can do.
Your Colorado Gives donation helps BCM prepare the next season of Denver programs and bring more young people onto the trail.
Every young person deserves access to the experiences, relationships, and opportunities that help them grow and connect. Give today and help a young person carry confidence, connection, and a lasting relationship with nature far beyond the trail.
Big City Mountaineers provides transformative experiences through connections to nature that strengthen life skills and build community for youth from disinvested communities
Big City Mountaineers (BCM) provides free, fully outfitted, professionally led outdoor programs for young people in Colorado who face barriers to outdoor access. Access is the vehicle. Youth development is the purpose. BCM facilitates transformative outdoor experiences that strengthen social-emotional wellbeing, deepen connection to nature, and foster positive youth development.
Since 1989, BCM has served more than 10,000 young people, conducted 800+ expeditions, engaged 5,000+ volunteers, led 100+ overnight camps, and provided 45,000+ nights under the stars.
Young people bring their own strengths, knowledge, and experiences to every program. BCM creates a setting where they can draw on those strengths, try hard things, build relationships, and discover their own capabilities. Caring adult mentors and skilled instructors help make sure every young person feels welcomed and supported. The confidence, resilience, and connection young people build outside travel with them into their homes, schools, and communities.
Our program model is built on People, Partnerships, and Places.
People: On expedition, each young person is paired 1:1 with an adult mentor. Professional trip instructors serve as facilitators and experienced guides, delivering intentional programming and an experience that is both challenging and safe. Instructors and volunteer mentors support young people as they work toward personal goals, and our thorough recruiting, vetting, and training process prepares every mentor for success.
Partnerships: BCM is the outdoor specialist within a broader youth development ecosystem. We partner with community-based youth-serving organizations that know their communities best, including immigrant and refugee support organizations, transitional housing communities, and youth development centers. Agency partners lead recruitment and preparation, and their staff join each expedition to support young people's needs and goals and help carry what they learn back home. Community partners bring the relationships and knowledge, and BCM brings outdoor experience and expertise. Through that teamwork, we build something stronger together.
Places: Our programs take young people into some of Colorado's most stunning landscapes, from the Flat Tops, Holy Cross, and Raggeds Wilderness areas to Rocky Mountain National Park. We select each location for its beauty and for the opportunities it offers young people to build new skills. Time outdoors gives young people room to connect with place, with each other, and with themselves. As their connection to nature deepens, so does their care for the places they explore.
