Falmouth is a working port town with a genuinely rich history, a beach within walking distance of the town centre, and a range of activities that keep kids engaged rather than just tired. Museums, boat trips, crabbing, gardens, and open coastal paths all sit within a compact area - most of it accessible without a car.
Pendennis Castle
Built by Henry VIII in the 1540s to guard the mouth of the Carrick Roads, Pendennis Castle sits on the headland above Falmouth with views across to St Mawes on the opposite shore. English Heritage runs regular cannon firing demonstrations in season and the Tudor gun deck is accessible to children. The site is large enough to occupy a good two hours - the inner keep, outer fortifications, and the 20th-century coastal artillery battery are all part of the same ticket.
Worth knowing: the coastal path runs directly past the castle, so combining a half-day at Pendennis with the cliff walk down to Gyllyngvase and back is a practical way to structure the day.
National Maritime Museum Cornwall
The National Maritime Museum Cornwall occupies a purpose-built waterfront building on the Falmouth docks, with full-size boats suspended from the ceiling of the main atrium. The harbour tower gives views over the working port and the estuary. Interactive exhibits on tides, navigation, and ocean science are pitched at a level that holds children’s attention, and the museum handles wet weather well enough to anchor a full half-day.
Family workshops run through school holidays - boat-building sessions and marine craft activities that run separately from the main admission. Check what’s on before visiting if the workshops are a priority.
Crabbing at Flushing and Mylor Harbour
Flushing village and Mylor Harbour, both on the west bank of the Carrick Roads, are the best crabbing spots within easy reach of Falmouth. The quayside walls at Mylor drop into calm, sheltered water with good visibility - crabs are visible from the surface in clear conditions. A bucket, a piece of string, and some bacon is sufficient kit; crabbing lines and small nets are sold in Falmouth’s fishing tackle shops and some of the harbour kiosks.
Both spots are a short drive from Falmouth town centre. Mylor also has a boatyard cafe for lunch after.
Boat Trip on the River Fal
Passenger boats run from Prince of Wales Pier in Falmouth up the River Fal to Truro through spring and summer. The route passes the wooded banks of the Carrick Roads, the Trelissick garden estate, and the King Harry Ferry crossing. Seals, herons, and kingfishers are regularly sighted on the upper reaches of the river. The return trip takes around two and a half hours total; it’s also possible to disembark at Truro and return by bus or train. Check current timetables and prices with Enterprise Boats, who run the main service.
Coastal Path: Pendennis Point to Maenporth
The section of the South West Coast Path between Pendennis Point and Maenporth beach runs for around 2 miles and is manageable for most children over 6. The path stays close to the cliff edge with clear views across Falmouth Bay towards the Roseland and St Anthony’s Lighthouse at the entrance to the Carrick Roads. Maenporth has a small beach and a café - a practical turnaround point for a family walk. The full round trip from Pendennis takes around 2 hours at a relaxed pace.
Swanpool Beach
Swanpool sits in a sheltered cove about a mile south of the town centre, and it is calmer than Gyllyngvase - good for younger children or nervous swimmers. The beach is smaller but rarely crowded. A freshwater lagoon (Swanpool Nature Reserve) sits directly behind the beach, home to swans, ducks, and a colony of the trembling sea mat, a rare marine organism. Pedalos and kayaks are available for hire in summer.
The Swanpool Beach Cafe is on the sand. There are public toilets and a small car park, though it fills quickly in summer - the walk from town takes about 20 minutes along the coast path.
Kimberley Park
When you need a free, central option to burn off energy, Kimberley Park is a 5-minute walk from the town centre. It has a children’s playground, a skate park, tennis courts, and a bowling green surrounded by mature trees. There is a cafe in the park. It works well as a 30-minute break between indoor activities, or as a picnic spot if you’re self-catering.
Gyllyngvase Beach
Gyllyngvase is the closest beach to Falmouth town centre - a 15-minute walk from the main shopping street. It holds Blue Flag status, has lifeguard cover through the main season, and is consistently calmer than the surf beaches on the north coast. The Gylly Beach Cafe sits directly on the sand with a terrace facing Falmouth Bay - a reliable option for lunch. Kayaking and paddleboard hire operates from the beach in summer.
National Seal Sanctuary
The National Seal Sanctuary is at Gweek, about 10 miles from Falmouth on the Helford River. It takes in injured and orphaned seals from around the Cornish coast, rehabilitates them, and releases most back to sea once fit. A permanent population of animals that cannot return to the wild lives at the sanctuary year-round.
Feeding sessions run at set times through the day - check the board at the entrance for the schedule. Children’s workshops run through school holidays covering marine wildlife and the recovery process. Allow 2-3 hours including the drive from Falmouth.
King Harry Ferry
The King Harry Ferry is a chain ferry that has crossed the River Fal between the Trelissick and Philleigh banks for over 130 years, cutting out a 27-mile inland detour. Cars and passengers cross in around 10 minutes. The crossing is not in Falmouth itself - it’s about 6 miles north via Feock - but it connects naturally to Trelissick Garden (National Trust) on the Trelissick bank, making a useful half-day loop.
The river views from the deck are good at any tide: wooded banks, moored yachts, and occasional seals on the mudflats. Check the King Harry Ferry website for current crossing times and prices.
Glendurgan Garden
Glendurgan is a National Trust garden about a mile from Trebah on the same stretch of the Helford River. The main draw for children is a cherry laurel hedge maze planted in 1833 - large enough to get properly lost in. The garden drops down a valley to the hamlet of Durgan and a small beach on the Helford. There is a play area and a children’s trail.
Glendurgan and Trebah can be combined in a full day if you start early. Both are on the same road from Mawnan Smith.
Rainy Day Options
Cornwall weather is unpredictable. When the rain sets in:
Ships & Castles Leisure Centre on Pendennis headland has a swimming pool, water slides, and a soft play area for younger children. A reliable 2-3 hour option when the beach is out.
Falmouth Art Gallery on the Moor is free and runs family-oriented exhibitions and workshops through school holidays. The gallery is small enough that it works as a 45-minute stop between other activities.
Penryn is a 10-minute drive from Falmouth town centre. Raze the Roof is an indoor soft play centre for younger children. Penryn itself has cafes and a market worth a look.
Trebah Garden
Trebah is 5 miles from Falmouth on the south bank of the Helford River, run by the Trebah Garden Trust. The garden drops 26 acres down a sheltered valley to Polgwidden Cove, a private beach accessible only through the garden. Giant gunnera lines the stream at the bottom; hundred-year-old rhododendrons and hydrangeas form a canopy on the upper slopes.
A children’s trail runs through the garden with activities for younger visitors. There is a play area near the beach with climbing equipment. Beach access is included in the garden ticket - sand and calm water, sheltered from the Atlantic swell.
Trebah is about 10 minutes from Falmouth via Mawnan Smith. Entry is charged; check the Trebah Garden website for current prices and seasonal opening hours.
Where to Stay in Falmouth with Kids
Merchants Manor Hotel and Spa has a swimming pool and spa - useful for rainy days. It’s dog-friendly and within walking distance of the town centre. Swallows Retreat is a two-bedroom pet-friendly cottage sleeping four, and one of the more affordable options in the area. For a B&B base, The Sandy Duck has parking and wifi included.

Practical Tips
Parking: The Quarry car park (long stay) is the most practical for a full day in town. The Events Square car park is closer to the Maritime Museum but fills earlier. Gyllyngvase and Swanpool both have their own small car parks.
Getting around: Falmouth is compact enough that most activities are walkable from the town centre. The bus to Trebah and Glendurgan runs from the Moor. The Seal Sanctuary at Gweek needs a car.
Budget: A family of four can fill a day for under £50 if you pick free activities (Kimberley Park, crabbing, coastal walk, Falmouth Art Gallery) and bring a packed lunch. Add a museum or garden visit for £30-50 on top.
