## Overview

Bihar Explorer is a travel and culture guide for discovering Bihar, with destination, food, festival, and broader editorial content alongside trip-planning, account, wishlist, and admin experiences. Visitors browse the React application; the Express API exposes content and account routes, with admin-protected content changes and MongoDB-backed models. The tree also shows map, gallery, blog, FAQ, contact, and newsletter capabilities, but their implementations are not sampled. Client-to-API wiring and several route/controller interactions are therefore not drawn where source evidence is unavailable.

Main entry points: [`client/src/App.jsx`](https://github.com/nayira1205/bihar-explorer/blob/main/client/src/App.jsx) (React app), [`server/app.js`](https://github.com/nayira1205/bihar-explorer/blob/main/server/app.js) (Express API), [`server/routes/destinationRoutes.js`](https://github.com/nayira1205/bihar-explorer/blob/main/server/routes/destinationRoutes.js) (Destination routes), [`server/controllers/destinationController.js`](https://github.com/nayira1205/bihar-explorer/blob/main/server/controllers/destinationController.js) (Destination service)
