Design for thumbs before anything else: generous tap targets, sturdy spacing, and persistent actions that remain visible as users scroll trail details or interpretive programs. Keep the path short—two to three decisive taps from discovery to date selection. Favor plain language, daylight-readable contrast, and forgiving headers. Ask for feedback after field tests, because hands-in-glove behavior often surprises carefully considered plans.
Let people search by activity, season, skill, and accessibility needs—not just names. Surface filters like wildlife considerations, trail conditions, guided options, canoe quotas, and family suitability. Cache frequent queries for weak networks and suggest nearby alternatives when capacity is tight. Encourage readers to comment on which filters clarified choices or created noise, and tune labels accordingly for shared understanding.
