St Mawes is a small harbour village on the eastern tip of the Roseland Peninsula, approximately 20 minutes from Tresillian Lodge via the King Harry Ferry. This guide covers what St Mawes offers, how to reach it from Tresillian and Truro, what to do and eat there, and how it fits into a wider Roseland stay.
What Is St Mawes?
St Mawes is a village of around 1,000 permanent residents at the southern end of the Roseland Peninsula, facing west across the Carrick Roads towards Falmouth. It sits at the point where the Percuil River estuary meets the main channel of the Fal, giving it a sheltered harbour that is rare on the Cornish coast, protected from Atlantic weather by the peninsula behind it, and facing one of Europe’s largest natural harbours.
St Mawes is not a resort. There is no beach within the village itself, no amusement facilities, and no large hotel complex. What it has is a compact, well-maintained waterfront, several good independent restaurants, a properly maintained castle, and an unhurried pace that makes it worth a half day or full day without effort.
How to Get to St Mawes from Tresillian and Truro
Via the King Harry Ferry (Recommended)
The King Harry Ferry is a chain-operated vehicle ferry crossing the Fal between Trelissick on the west bank and Philleigh on the east. From Tresillian Lodge:
- Take the A390 west towards Truro for approximately 3 miles
- At Truro, follow signs for Feock / King Harry Ferry (B3289 south through Playing Place)
- The ferry runs continuously, no booking required
- The crossing takes approximately 7 minutes
- From the Philleigh landing, follow the B3289 south for approximately 6 miles to St Mawes
Total journey time: 25–35 minutes depending on ferry wait, typically under 10 minutes at most hours.
Ferry operating hours: Approximately 7:45 am to 9 pm in summer (May–September), slightly reduced in winter. Evening trips for dinner should allow time to check the last crossing or plan the longer inland return route.
Ferry cost: As of 2026, the return vehicle crossing costs approximately £10–£12 for a standard car and driver. Check current rates at the King Harry Ferry website before travel.
Via the Inland Road Route
The A390 east from Truro towards St Austell, then south via Tregony and the B3078 down the Roseland. Adds approximately 20–25 minutes each way. Use this route for returning to the lodge after the last ferry crossing of the evening.
By Boat from Falmouth
Falmouth Ferries operates a passenger service between Falmouth and St Mawes from approximately April to October. If your visit includes Falmouth, combining both destinations by water is worth planning: cross to St Mawes from Falmouth Harbour, walk and eat, then return by boat.
St Mawes Castle
St Mawes Castle is one of Henry VIII’s Device Forts, the chain of coastal artillery castles built in the late 1530s and early 1540s to defend against French and Spanish invasion following Henry’s break with Rome.
The castle sits on a headland at the harbour entrance, commanding the Carrick Roads anchorage. Its cloverleaf ground plan, a central circular tower flanked by three semi-circular bastions, was designed for overlapping fields of fire across the water approach. It faces Pendennis Castle on the Falmouth side; the two forts were designed to catch any hostile fleet in crossfire.
English Heritage manages the castle. It is open most of the year with seasonal variation in hours. Admission charges apply; English Heritage members enter free. The headland walk around the exterior is free and takes 20–30 minutes.
What to Do in St Mawes
Walk the waterfront. The quayside runs approximately 400 metres between the harbour and the castle headland. An hour of walking covers the village comprehensively.
Eat well. The St Mawes Hotel is the best-known restaurant, with a focus on local seafood and Cornish produce. The Idle Rocks Hotel also has a serious kitchen. Booking is advisable at the hotel restaurants in summer.
Visit the Saturday Market. A small seasonal market on Saturday mornings, primarily local produce and crafts. Good for self-catering guests picking up local food.
Walk to Zone Point. The coastal path south from the castle leads to Zone Point, the southernmost tip of the Roseland Peninsula. Approximately 3 km each way, relatively flat. Allow 2 hours return.
Take the ferry to Falmouth. The passenger ferry from St Mawes Quay to Falmouth Harbour runs through the summer season. Falmouth has more shops, the National Maritime Museum Cornwall, Pendennis Castle, and a larger restaurant scene.

- Portscatho (5 miles north on the east coast): smaller harbour village, beaches at Porthcurnick and Towan nearby
- Pendower and Carne Beach (6 miles north from St Mawes, 12 minutes): Roseland’s longest beaches, generally less crowded

St Mawes as Part of a Tresillian Lodge Stay
Guests at Tresillian Lodge who have not visited the Roseland before typically visit St Mawes during their stay. A suggested two-outing Roseland sequence:
Outing 1: King Harry Ferry to Trelissick Garden for a morning walk, then south to St Mawes for lunch on the quayside. Return via the ferry in the afternoon.
Outing 2: King Harry Ferry, then north along the eastern Roseland to Portscatho, then south to Carne and Pendower Beach for the afternoon.
These two outings cover the best of the accessible Roseland without repetition and return to the lodge in time for the hot tub in the evening.
Practical Notes
- Parking: The harbour car park fills quickly in summer by mid-morning. Arrive before 10 am or after 3 pm.
