Spending time in nature can be healing for former members of the armed forces.
A Pew Research Center survey found that roughly one in four veterans say the transition back to civilian life was at least somewhat difficult. This is especially true for those who return home with stress or trauma. About 11-20% of veterans are believed to experience post-traumatic stress disorder (PTSD) in a given year and many do not receive mental health treatment.
- If you or a loved one need access to free and confidential mental health resources, the CDC has more information.
Research suggests that spending time outdoors can support veterans' mental health by helping reduce stress, improve mood, and strengthen social connections. Activities ranging from hiking and gardening to organized outdoor recreation programs may offer meaningful opportunities for veterans to improve their well-being.
The US Department of Veterans Affairs recommends that doing something as simple as taking a walk or a hike, riding a bike, or doing yard work or gardening can help veterans cope during times of stress.
Outdoor Experiences and Nature Based Therapy Have a Positive Impact
“Nature-based therapy” is an umbrella term for therapy based on experiences and activities in a natural setting. Being in nature while working through trauma can help veterans handle challenging life situations and improve their sense of well-being.
Research into nature-based approaches to mental health continues to grow. While studies have identified promising benefits for veterans, including reduced stress, improved mood, and stronger social connections, researchers are still working to understand which activities are most effective and how long the benefits last.
The following studies highlight some of these findings.
Comparison of Indoor Versus Outdoor Mindfulness Interventions for Veterans
Researchers compared indoor and outdoor mindfulness programs involving 41 veterans with diagnosed mental health conditions. Veterans participated in six group sessions, either indoors or in a natural setting. The outdoor group had a higher rate of program completion, and researchers found differences in PTSD symptom improvements between the groups. The findings suggest that incorporating nature into mental health programs may help veterans engage in treatment and support their well-being.

A Structured Forest Therapy Intervention Enhancing the Nature Connection, Mood States, and Satisfaction With Life of US Veterans With PTSD
Researchers studied 35 US veterans with PTSD who participated in a guided, one-hour forest therapy walk. The experience included mindfulness activities designed to help participants connect with nature through their senses. Following the session, veterans reported reduced anxiety, depression, anger, and fatigue, along with improvements in mood, connection to nature, and life satisfaction. The findings suggest that even relatively brief experiences in nature may offer mental health benefits.

A Green and Pleasant Helping Hand: Examining the Effects of Outdoor Recreation on Veterans With PTSD
Researchers in the UK interviewed veterans participating in an outdoor recreation program designed to help manage PTSD symptoms. Participants described how spending time in peaceful natural settings helped them relax, connect with fellow veterans, and discuss difficult experiences without fear of judgment. Veterans also reported improvements in feelings of safety, sleep, and overall well-being. The findings highlight the potential value of outdoor recreation and peer support in helping veterans manage the effects of trauma.

Mental Health Outcomes of Peer-led Therapeutic Adventure for Military Veterans
Skepticism about therapy is a significant barrier that holds back veterans from getting help with mental health issues. Therapeutic adventure activities can provide support without the stigma. In this study, veterans recorded improvements in overall psychological well-being immediately following time spent on Military Outdoors camping trips hosted by the Sierra Club.

Outdoor Recreational Activity Experiences Improve Psychological Wellbeing of Military Veterans With PTSD
Researchers in the UK found that group outdoor activities such as surfing, falconry, or horseback riding decreased participants' anxiety and stress while increasing social connections. A four-month follow-up survey concluded that the effects were sustained over time.

Everything Just Seems More Right in Nature'
Danish veterans participated in 10 weeks of nature-based therapy at an arboretum and were interviewed about their experience. The results indicated that the veterans had new tools to use in stressful situations and experienced an improvement in PTSD symptoms. Feeling relaxed helped with the healing process.

Natural Medicine: Wilderness Experience Outcomes for Combat Veterans
Researchers with Warrior Expeditions analyzed how engaging in a six-month thru-hike of the Appalachian Trail impacted the mental health of combat veterans. Feedback from participants revealed themes around social re-connection, inner peace, and reflection. Respondents reported, “I accept myself more for who I am” and that their time on the trail was “the time I [was] taking to heal.”

Nature-Based Resources for Veterans
Do you know a veteran who might benefit from spending more time outside? Resources are available to help military members and their families experience the benefits of nature.
- US Vet Connect helps veterans locate organizations, explore outdoor opportunities, and connect to programs across the country
- Veterans can explore opportunities to work or volunteer on public lands managed by the National Park Service (NPS), Bureau of Land Management, or US Forest Service. Did you know? NPS employs over 4,000 veterans, which accounts for more than 20% of their paid workforce.
- US military veterans and Gold Star Families are eligible for a free Military Lifetime Pass, which covers entrance and standard day-use fees at national parks, national forests, wildlife refuges, and other participating federal recreation sites. Current military members and their dependents are eligible for a free Military Annual Pass.
Learning How Nature Supports Veterans’ Well-Being
Dr. David Havlick, Professor of Geography and Environmental Studies at the University of Colorado–Colorado Springs, discussed how outdoor programs support veterans’ mental health in a NEEF webinar.
The conversation highlighted how nature immersion, outdoor recreation, and public lands contribute to recovery—particularly for those experiencing PTSD, and offered insights into how these programs can continue to evolve to support veterans’ well-being.
Helping Veterans Connect With Nature Through Grants
NEEF is also helping veterans experience the benefits of nature through its 2026 Veterans and Nature Grant. The grant supports organizations creating outdoor recreation, conservation, and wellness programs that help veterans connect with nature and one another. Explore the funded projects and meet this year's grantees.
