A Day Trip to St Mawes from Falmouth: The Ferry, the Castle and the Roseland Walks

There are people who use Falmouth as a launchpad for "doing Cornwall": car days to the Lizard, drives to Land's End, the Eden Project, Tintagel. There is another shape that suits a long weekend better. You stay put, you walk a lot, you eat well, and on one of your days you take the ferry across the harbour to St Mawes. No car. No motorway. A twenty-five minute crossing, a small Cornish village on the other side, two beautiful walks to choose between, an English Heritage castle, lunch by the quay, and the same ferry back at golden hour.

This guide is for that day.

The St Mawes Ferry from Falmouth

The day starts at Prince of Wales Pier in central Falmouth, where the passenger ferry to St Mawes sails several times a day. The crossing takes twenty to twenty-five minutes across the wide mouth of the Carrick Roads, the broad estuary where the Fal River meets the sea.

The ferry is one of the highlights of the day, not just transport. From the deck you see:

• Falmouth harbour and Pendennis Castle receding behind you, framed by the town's pastel waterfront
• The deep-water shipping channel through the Carrick Roads, where the largest ships call into Falmouth's working port
• St Mawes Castle appearing on the headland as you approach the Roseland shore
• St Mawes harbour itself opening up in front of you as the ferry pivots into the village

If the weather allows, sit on the open deck. The view is the point.

No advance booking is needed for the regular service; turn up at Prince of Wales Pier, pay on board or at the kiosk, and pick your departure. A return is cheaper than two singles. Check the operator's current timetable before the day, especially in winter.

A morning in St Mawes village

The ferry drops you on St Mawes harbour at the heart of the village. The first hour is naturally for the village itself: the curving harbour wall, the pastel-painted cottages above the quay, the harbour-front pubs and the small lanes climbing the hill behind.

St Mawes is a working Cornish harbour village rather than a manicured tourist set. Fishing boats still come and go from the quay. The village has good independent shops, a couple of galleries, a deli or two, and a row of harbour-front restaurants and pubs. Ice cream on the quay is a long-established tradition. Take an hour, no more, to wander before deciding on the day's bigger walk.

St Mawes Castle

A ten-minute walk along the seafront west of the village brings you to St Mawes Castle, one of Henry VIII's coastal artillery forts. Built in the 1540s as part of the defensive line against French and Spanish invasion, paired with Pendennis Castle across the harbour mouth in Falmouth. The two forts together commanded the entrance to the Carrick Roads.

St Mawes is the smaller and more elegant of the pair: a clover-leaf design with three semicircular bastions arranged around a central tower, set on a small headland with panoramic views back across the harbour. English Heritage operates the site. Allow around an hour for a relaxed visit. Doing both castles on a long weekend (Pendennis one day, St Mawes the next) is one of the more satisfying heritage pairings on this coast.

The Place Ferry and the walk around St Anthony's Head

For the day's walk, the first option is the most spectacular. A second small ferry, the Place Ferry, runs short hops across the Percuil River from St Mawes harbour to Place, a tiny landing on the opposite shore. The crossing is a few minutes long. From the Place jetty, the South West Coast Path runs around the wooded creekside and out to St Anthony's Head.

The walk climbs from the creek through woodland, then opens onto the open headland of St Anthony, with views back across Falmouth Bay to Pendennis Head and the Carrick Roads, and out to sea south towards the Lizard. The St Anthony's Head lighthouse, perched on the headland, is the visible focal point. The views from up here are genuinely some of the best in Cornwall: the bay, the Roseland coves, the open Channel.

Allow around two hours for the full circular back to Place, longer if you stop. The walk is moderate but not strenuous; good shoes recommended.

The alternative: walking inland to St Just in Roseland

The second walking option is gentler and more inland. From St Mawes, a three-mile walk on country lanes and footpaths leads to St Just in Roseland, a small village famous for its riverside church.

The church sits on a steep, wooded bank above a tidal creek, in a subtropical garden of palms, magnolias, gunnera and tropical shrubs that thrive in the sheltered microclimate. Reckoned to be one of the most beautiful churchyards in Britain. The graveyard winds down to the water's edge. At low tide the creek empties to mud; at high tide it fills like a small Italian harbour.

Allow around an hour and a half each way. For lunch, the Roseland Inn at Philleigh and the Plume of Feathers at Mitchell are the proper pub options if you have the legs to extend the walk; otherwise, wait until you are back in St Mawes harbour or back in Falmouth for a proper sit-down. The standard move is St Mawes to St Just to St Mawes, with the church and its garden as the turnaround point.

Lunch on the harbour-front

Whichever walk you choose, lunch back on St Mawes harbour-front is the natural recovery. The options span the price range:

• The Idle Rocks: the Olga Polizzi-owned hotel and restaurant on the harbour, the smart end of St Mawes dining
• Hotel Tresanton: another long-established small luxury hotel with a good dining room and a terrace looking out across the bay
• The Watch House: a lively independent bistro with a strong reputation
• The Victory Inn: the proper Cornish harbour-pub option, real ales and fresh-fish menus
• The Rising Sun and other pubs along the quay: easy walk-in options

Book the smart restaurants ahead in season. The pubs accept walk-ins outside peak Saturday nights.

The ferry back at golden hour

The right ending for the day is the late-afternoon or early-evening ferry back to Falmouth, with the light dropping over the water and Pendennis Head ahead of you. Time it to one of the later sailings if you can: the crossing is at its best with the sun low. Check the timetable for the day; sailings reduce after late afternoon, particularly outside summer.

The walk back from Prince of Wales Pier to dinner or back to the cottages is short. After a slow day on the ferry and on the headland, an early dinner and an early night feels exactly right.

How a St Mawes day slots into a Falmouth weekend

The standard pattern for a long weekend in Falmouth, with St Mawes as one of the days, looks like this:

• Friday afternoon: arrive, settle into the cottage, slow first dinner in Falmouth
• Saturday: a Falmouth day. Maritime Museum, Gylly Beach, dinner at the Cornish Bank or a seafront restaurant
• Sunday: the St Mawes day. Ferry over, walk, lunch on the harbour, ferry back at golden hour
• Monday morning: a slow breakfast and the drive home, or another quiet Falmouth day if you have stretched it out

For a four-night stay, add a third day for Verdant Taproom in Penryn or one of the longer walks from Falmouth.
