Alpine Trails — Hiking Trip Planner

A mobile-friendly, installable PWA I built and deployed to make planning and navigating a hiking trip with friends easier. A fast trail finder for two base regions — Ortisei / Val Gardena (Dolomites) and Kranjska Gora (Julian Alps · Triglav National Park) — with trails drawn on an interactive OpenStreetMap, colour-coded by difficulty, plus search, filtering and a card per trail showing distance from your base, peak height, length, ascent and walking time. Installs to your home screen and works offline.
