Cycling is very popular, so you’ll be tripping over bicycles for hire. Prices range from as little as €5 per day for a boneshaker, up to €20 for a decent mountain bike. In Kos Town, Escape Rentals offers a good range of bikes, including electric bikes, and reasonable rates.
Kos Mountainbike Activities offers bike rentals and guided tours.
The massive line of boats moored in Kos Town offer excursions around Kos and to nearby islands. A ‘three island’ day trip to Kalymnos, Pserimos and Platy costs around €30, including lunch, while you can find day trips to Bodrum for as little as €15.
The island's main bus station is located well back from the waterfront in Kos Town. It is the base for KTEL, which has services to all parts of the island, including the airport and south-coast beaches.
