Recurrent hydrometeorological disasters can create prolonged psychosocial challenges for students, underscoring the need for school-based support. This article reports a descriptive qualitative evaluation of a community engagement program designed to prepare junior secondary school counselors to facilitate Adventure-Based Counseling (ABC). Thirty-seven counselors affiliated with the Musyawarah Guru Bimbingan dan Konseling (MGBK) of Bandung Regency took part in six online sessions, followed by a 3.5-hour face-to-face experiential session at SMP Negeri 1 Katapang, West Java, organized in four group stages that included a Tree of Hope reflection and three core challenges (Ular Tangga, Traffic Jam, and Panic Twin). The program was organized using the APPLE Facilitation Model (Assess, Plan, Prepare, Lead, and Evaluate), with MGBK acting as co-designer and co-implementer. Data were drawn from facilitator observation, participant journals, and written Tree of Hope statements of gratitude and hope, which were analyzed thematically and then mapped onto the five dimensions of Posttraumatic Growth (PTG). The reflections expressed gratitude, supportive relationships, recognition of personal capabilities, future aspirations, and spiritual meaning, corresponding conceptually to the PTG dimensions of appreciation of life, relating to others, personal strength, new possibilities, and spiritual change. These PTG-related reflections indicate perceived learning and meaning-making during the training; they do not constitute evidence of increased PTG, demonstrated counselor competency, or improved student well-being, none of which was directly assessed. The program offers a practical example of ABC-oriented professional development for school counselors in disaster-prone areas; structured assessment of facilitation skills and follow-up monitoring of school-based implementation are needed to establish its effectiveness.
