Discovering the Isles of Scilly: An Ultimate Guide to Cornwall’s Atlantic Archipelago

Perched roughly 30 miles off the dramatic coast of Cornwall, the Isles of Scilly offer a picturesque, stunning escape that feels worlds away from the British mainland. For travellers planning a first-time excursion, navigating the vast array of sights, islands, and experiences can present a delightful challenge simply because there is so much choice.

Over years of repeated visits, travellers and holidaymakers have discovered that this magical set of islands benefits immensely from the Gulf Stream and the Atlantic Drift. These ocean currents bring noticeably warmer waters and milder weather patterns directly to the shores of the archipelago, fostering an environment where subtropical plants thrive and coastal landscapes dazzle under the sun.

How to Get to the Isles of Scilly

Reaching this remote island group is surprisingly straightforward, with transport links catering to both air and sea travellers. Visitors frequently opt for SkyBus flights, which touch down directly on St Mary’s Island. Operating from airports including Exeter, Land’s End, and Newquay, these flights offer a convenient and efficient entry point to the islands, and passengers are even permitted to bring their dogs onboard.

Alternatively, travellers can head to the southwestern tip of mainland Cornwall and board the Scillonian III ferry from Penzance. The maritime crossing typically takes between two and a half and three hours, depending entirely on sea and weather conditions. While the ferry remains a popular choice for those already exploring West Cornwall, passengers are advised that the open sea can become quite choppy on particularly windy days.

1. St Agnes and Porth Conger

As the southernmost populated island in the archipelago, St Agnes serves as a charming destination for a day trip. Easily accessible via water taxis and scheduled boat services operating from neighbouring islands, St Agnes captivates visitors with its unspoiled natural beauty. Schedule adjustments can occur based on tidal shifts and seasonal changes, making it essential for travellers to check local boat timetables upon arrival.

Upon docking at Porth Conger Quay, visitors can set out on foot to explore the island’s scenic landscapes. Around lunchtime, the Turk’s Head provides a traditional pub experience complete with a beer garden and decked area offering expansive views. Recognized as the most southerly pub in the entire British Isles, it stands out as a prominent landmark on St Agnes.

A gentle walk through the island’s small settlement reveals quiet spots to relax, alongside the local Post Office where visitors can purchase souvenirs and mail postcards. Additional local highlights include a cup of tea at the Coastguards Lookout café, views of the historic St Agnes Lighthouse and St Agnes Church along New Lane, and a direct walk across a sandy bar connecting St Agnes to the neighbouring island of Gugh.

2. St Mary’s and Hugh Town

Most itineraries naturally include St Mary’s Island, home to the archipelago’s primary commercial centre, airport, and ferry port. While it functions as the region’s main hub, the community retains the intimate scale and quiet atmosphere of a small town. Visitors often split their accommodations across different islands, such as spending several nights on Tresco before concluding their trip on St Mary’s to secure greater flexibility with return flights.

Arriving in Hugh Town opens up opportunities to rent a golf buggy—a popular transport method facilitated by local providers like Scilly Carts—to navigate the narrow country roads and explore the wider island. Important historical stops include St Mary’s Garrison Walls, a free-to-enter English Heritage site offering insights into the island’s defensive history within a brief 25-minute walk. Porthcressa Beach, situated right on the edge of Hugh Town, offers shallow waters and soft white sand ideal for swimming. Further exploration via buggy leads to Peninnis Head, Porth Hellick, and ancient sites such as the Down Burial Chamber, while Juliet’s Garden provides local dining options overlooking the coastline.

3. St Martin’s

St Martin’s provides a quieter, more laid-back alternative to the busier hubs while offering exceptional coastal scenery. Small ferry boats regularly transport visitors to Higher Town Quay, allowing for independent exploration of the island’s beaches and coastal paths. Higher Town Bay provides accessible sandy shores close to the arrival point, while local establishments serve fresh, traditional fish and chips seasoned with vinegar.

The island also features the St Martin’s Vineyard and Winery, offering local wine tastings. Visitors frequently spend time at Great Bay Beach, rent kayaks to navigate the shallow shorelines, and visit the Seven Stones Inn, a popular local pub known for serving Cornish beers and traditional pasties.

4. Porthcressa Beach

While not the only coastal stretch on the archipelago, Porthcressa Beach on St Mary’s Island stands out for its remarkable accessibility directly from the roads of Hugh Town. On sunny days, visitors utilize the wide sandy expanse for swimming and sunbathing before stopping for lunch at local establishments like Dibble and Grub, known for its selection of sandwiches and cocktails.

5. Peninnis Lighthouse

Situated near Porthcressa Beach on St Mary’s Island, the area surrounding Peninnis Lighthouse offers rugged coastal scenery ideal for walking. The cliff paths and rock formations provide some of the best pedestrian exploring opportunities on the island, particularly during the evening hours as the sun sets over the Atlantic.

6. Tresco Abbey Garden

Tresco Abbey Garden stands as one of the Isles of Scilly’s most famous and striking attractions, serving as a direct testament to the warming effects of the Gulf Stream. Established in the 19th century, the garden accommodates a vast collection of Mediterranean, South African, and Australasian plants, trees, and flowers that would struggle to survive elsewhere in the United Kingdom. Visitors frequently spend a couple of hours walking the peaceful, terraced pathways of the garden.

7. Tresco Island

Beyond its renowned gardens, Tresco Island offers visitors a tranquil environment characterized by bicycle tracks, coastal paths, and historical ruins. Travellers often spend multiple nights on the island to fully experience its slower pace of life. Historical points of interest include the shoreline ruins of Cromwell’s Castle and King Charles’s Castle, which offer a glimpse into the island’s military past. The small village of New Grimsby features the New Inn, a traditional pub positioned near the local quay. Throughout the island, visitors encounter numerous honesty boxes offering local produce, eggs, and handmade crafts.

8. Innisidgen Lower and Upper Burial Chambers

Located on the northern side of St Mary’s Island, the Innisidgen Lower and Upper Burial Chambers represent prehistoric architecture dating back to approximately 2,500 BC. Maintained by English Heritage, these free-to-enter ancient monuments require sturdy footwear due to the uneven surrounding pathways. Nearby prehistoric sites, such as Bant’s Carn Burial Chamber and the Halangy Down Ancient Village, offer additional opportunities to explore the region’s ancient human history within a short visit.

9. Bryher Island

Lying just off the coast of Tresco, Bryher is a small, peaceful island characterized by rugged coastlines and quiet sandy coves. Boats typically dock at Church Quay, allowing visitors to traverse the island entirely on foot. Walking the coastal paths leads past Richard Pearce’s Artist Studio, which showcases local artwork, and brings visitors to Fraggle Rock and the Harbour View café, which features a beer garden overlooking the water.

10. Teän Island

Positioned near St Martin’s Island, Teän is an unpopulated island characterized by entirely untouched and unspoilt beaches. Because the island lacks shops, public facilities, and permanent residents, visitors must bring sufficient supplies of water, food, and sun protection. Walking trails across the island lead up to Great Hill, offering panoramic views across the surrounding archipelago.

11. Gugh Island

Connected to St Agnes Island by a narrow sandy bar that is easily crossable on foot during low water, Gugh Island maintains a near-permanent quiet, with only a single working farm operating on its land. The island can be fully explored on foot in under an hour, offering serene coastal views and the historic Old Man of Gugh, a prominent standing stone dating back to the Bronze Age.
