This masterplan reimagines the Pulau Besar waterfront as an eco-friendly, culturally-sensitive ecotourism destination. The design integrates thoughtful elements such as Buggy Trails, Viewing Decks, and Pedestrian Pathways, providing accessible exploration without disrupting the environment. Unique "Penyangga" greenery, inspired by local traditions, uses native plants to form natural buffers against erosion, wind, and sea-level rise, creating a resilient landscape rooted in cultural heritage. The illustrations include proactive adaptation strategies for future sea-level rise, visualized from 2022 to 2100, highlighting innovative, sustainable solutions. Each section is meticulously illustrated to convey complex concepts with clarity, balancing aesthetic appeal and functionality. This project exemplifies sustainable tourism, offering an engaging, educational, and immersive experience that respects both nature and local culture
