Mill Bay Beach, being an estuary-side beach, typically offers calm and sheltered waters, making it very suitable for swimming, especially for families. The sandy bottom is generally pleasant underfoot. While the estuary location means less exposure to large waves, it's always important to be aware of tidal currents, which can be stronger in estuaries. There are no lifeguards, so swimmers should exercise caution. The water quality is generally good for bathing.

For the best combination of pleasant weather and fewer crowds at Mill Bay Beach, consider visiting during the shoulder seasons (late spring or early autumn). Weekdays outside of school holidays are also ideal. While summer offers the warmest weather, it also brings the most visitors. Early mornings or late afternoons can provide a more serene experience even during peak times. The beach's 'hidden' nature helps manage crowd levels.

Mill Bay Beach is uniquely appealing for boat access, being located across the estuary from Salcombe. Many visitors arrive by ferry from Salcombe or by their own small boats, which can be beached directly on the sand. For land access, it's typically a walk along coastal paths from nearby areas, with limited direct vehicle access. Parking might be available further afield, requiring a walk. The ferry from Salcombe is a popular and scenic option.

Mill Bay Beach is a relatively natural and undeveloped sandy beach. While there might be very limited seasonal provisions, there are generally no permanent food vendors or formal lodging options directly on the beach. Visitors are usually advised to bring their own refreshments. For a wide range of dining and accommodation choices, the vibrant town of Salcombe, just across the estuary, offers numerous hotels, guesthouses, restaurants, and shops.

Mill Bay Beach is highly appealing for families due to its soft sand, calm estuary waters, and generally safe swimming conditions. The ability to access it by boat adds an exciting element for children. Its 'hidden' and scenic qualities mean it often feels less crowded than larger resort beaches, providing a more relaxed environment for families to play, build sandcastles, and enjoy the water. The beautiful surroundings enhance the family beach day experience.
