By Air: Newquay Cornwall Airport (NQY) has domestic flights from London and a few European routes. Most international visitors fly into London and continue by train or rental car (roughly 4.5-5.5 hours by road from London).
Trains: Great Western Railway runs the scenic main line from London Paddington to Penzance (about 5 hours), with a branch line to St Ives offering dramatic coastal views. Branch services to Newquay and Falmouth also exist but run less frequently.
Buses: First Kernow operates routes across the county, useful for reaching towns but with limited frequency to more remote villages and attractions.
Rental Cars: Highly recommended for exploring beyond the main towns - narrow country lanes with passing places are typical, and many of Cornwall's best sights (mining ruins, prehistoric sites, remote coves) are only practically reachable by car. Roads are generally well maintained but can be very slow-going and congested in peak summer weeks.
Park & Ride / Village Parking: Several villages (Polperro, sometimes St Ives) restrict or heavily limit in-village parking - use designated car parks and walk or take a local shuttle in.
Ferries: Small foot-passenger ferries cross estuaries efficiently, e.g., Falmouth to St Mawes, Fowey to Polruan - often faster than driving around.
