From Edinburgh, aim for the earliest practical connection you can manage so you still have a proper first day on St Mary’s. In September, the smoothest route is usually a morning flight via Land’s End, Newquay, or Penzance connections, with total door-to-door time anywhere from about 4 to 7 hours depending on schedules and baggage handling; if you’re doing a ferry combination instead, build in extra buffer for weather and connections. Pack light if you can, because once you reach the quay or airport on St Mary’s it’s an easy walk into Hugh Town with small bags, or a short taxi if you’d rather save energy after the travel. For a first proper meal, head straight to The Mermaid Inn in Hugh Town for lunch — it’s one of those reliably Scillonian places where you can settle in, shake off the journey, and start feeling the rhythm of the islands. Expect roughly £20–35 per person and about 1 to 1.5 hours here; it’s a good idea to arrive with a bit of flexibility, especially if your transfer runs late.
After lunch, wander over to Old Town Church, which is one of the calmest, most atmospheric corners on the island. It’s an easy low-effort stop — about 45 minutes is plenty — and a nice way to ease from travel mode into island mode. If the weather is settled, continue along to Porthcressa Beach for a slow stroll on the sand and, if you’re up for it, a quick paddle or swim; this is the kind of beach that works well even on a short first day because it’s so close to town. Give yourselves around an hour here, and keep a towel or light layer handy because September breezes can make it feel cooler than it looks. Everything in this part of the day is nicely walkable from Hugh Town, so there’s no need to overthink transport — just take it at island pace and leave room for detours.
Later on, make your way up to Buzza Tower above Hugh Town for the best first-day orientation on St Mary’s. It’s especially lovely in late afternoon when the light softens over the harbour and the outer islands start to stand out; allow about 45 minutes, including the climb and a bit of time to soak in the view. From there, head back down into town for an easy dinner at The Atlantic Inn, which is a sensible, relaxed choice close to where you’re likely staying. It’s the sort of pub where you can have a proper meal, a pint or a glass of wine, and be done without any fuss — budget roughly £25–40 per person and about 1.5 hours. Since you’ll have had a travel-heavy day, keep the evening straightforward and aim for an early night so you’re fresh for tomorrow’s island time.
Start with an easy, practical breakfast stop at The Scillonian Shop on the Hugh Town waterfront — this is the kind of place locals use for coffee, pastries, sandwiches, and picnic bits before heading out on the water. Go straight here first, then stroll a few minutes down to Hugh Town Harbour to watch the boats, check the tide, and get that unmistakable island rhythm. It’s worth lingering by the quay for about 45 minutes: the harbor front is small, busy, and oddly soothing, with fishing boats, supply runs, and day-trippers all mixing in one place.
From Hugh Town Quay, board Tresco Boat Services for the hop across to Tresco — aim for a mid-morning sailing, ideally around 9:00–10:00, so you keep the day feeling spacious rather than rushed. Services are weather- and tide-dependent, so check the quay boards the day before and again on the morning; tickets are typically around £10–20 one way. If you want to break up the day with a food stop, fit in St Agnes Bakery when schedules allow: it’s the sort of detour that works best if you’re already doing a boat-connection day, with fresh bakes and coffee that make a very good light lunch around £8–15 pp.
Head back to St Mary’s for a late-afternoon drink or a more polished dinner at Star Castle Hotel up on the Garrison — the setting alone makes it worth it, with proper island views and a sense of being somewhere slightly special without feeling formal. Expect around 1.5–2 hours and roughly £30–55 pp depending on how much you order. If you’d rather keep things low-key, finish instead at Juliet’s Garden near Porthcressa, where you can have a relaxed dinner with sea views and an easy wander back to your base in Hugh Town afterward; it’s one of the best “no fuss, still memorable” evening spots on the island, and a nice way to end a full day without overcomplicating the logistics.
Take the Tresco Boat Services ferry from Hugh Town Quay to New Grimsby as early as you can manage, ideally on the 8:30–9:30 sailing. It’s a short hop, but on a no-car island the timing matters: with check-in, boarding, and the walk from the quay into the island’s main paths, you’ll want to keep luggage light and hand-luggage sized if possible. Once you land, it’s a pleasant 15–20 minute walk inland to Tresco Abbey Garden, and the earlier you arrive, the better — the subtropical planting is at its freshest in the cooler morning light, and you’ll have the place much more to yourself before the day boats settle in.
Spend around two hours wandering Tresco Abbey Garden properly rather than rushing through. This is the kind of place where you move slowly: palms, giant tree ferns, bright agapanthus, and sheltered paths that feel almost unreal for the far southwest of Britain. Admission is typically in the teens per person, and it’s very easy to combine with the nearby Valhalla Collection without needing any extra logistics. The collection is small but memorable — carved ship figureheads and maritime pieces with a wonderfully eccentric Scilly feel — and 30–45 minutes is enough to do it justice without turning the morning into a museum crawl.
For lunch, head down to The Flying Boat Café in New Grimsby. It’s an ideal reset point: right by the water, simple to reach on foot, and much less faff than trying to make a long, complicated lunch plan. Expect roughly £20–35 per person depending on whether you’re doing sandwiches, seafood, or a more leisurely sit-down plate, and allow an hour or so so you don’t feel pinned to a schedule. If the weather is behaving, this is a good place to linger over coffee and watch boats come and go before drifting into the quieter part of the day.
After lunch, make your way to Applebay Beach on the west side and give yourself at least a couple of unrushed hours there. This is the classic Tresco afternoon: sand, clear water, and enough space to properly switch off. Bring a towel, layers for the breeze, and something to read; even in September, conditions can change quickly, so a windproof layer is smart. If you feel like walking, follow the shoreline at your own pace rather than trying to “see everything” — on Tresco, the best afternoons are the ones where you let the island set the rhythm.
Keep dinner simple and walkable with a table at the Duchy of Cornwall Beach Restaurant or another easy Tresco dining spot near New Grimsby or the settlement area, so you’re not worrying about dark lanes or an extra transfer after sunset. Plan on about 1.5 hours and roughly £30–50 per person for a proper island dinner. September evenings can feel wonderfully calm, so if the sky is clear, it’s worth a slow post-dinner stroll before turning in — but keep an eye on the ferry schedule for the next day if you’re planning a return via Hugh Town.
Take the Tresco Boat Services return ferry back to Hugh Town, St Mary’s in the mid-morning if you can — ideally on a sailing around 9:00–11:00, which gives you a comfortable buffer before your onward connection. From the quay, it’s a short, easy walk up into town with bags, and if the tide and weather are in your favour you’ll get one last lovely approach into the harbour. Keep your departure day relaxed: boats can shift a little with conditions, so don’t cut it close.
Once you’re back on St Mary’s, head straight up to Garrison Walls for a final proper island walk. This is the one to do when you want the full Scilly feeling before you leave: open sea, big skies, and that elevated look back over Hugh Town, the harbour, and the smaller islands beyond. Allow about an hour if you’re strolling rather than power-walking, and wear decent shoes — the paths are straightforward, but the ground can be uneven and breezy.
Drop back into Hugh Town for lunch at The Crab Shack, right by the harbour and ideal on a departure day because you’re never far from your bags or the quay. This is the place to go if you want a final seafood-heavy meal without faffing: think crab, shellfish, and simple plates that feel very Scilly. Expect roughly £25–45 per person, and if you can, book ahead or arrive early for a table; otherwise, queueing is usually part of the experience and it moves at island pace.
After lunch, make a short stop at the Isles of Scilly Museum. It’s compact, easy to fit into a travel day, and a nice way to give context to everything you’ve seen over the last few days — shipwrecks, island life, old photos, and the practical story of how these islands actually work. You only need about 45 minutes, and it’s close enough to the quay that you won’t feel rushed.
If you’ve got a bit of time left before leaving, walk down to Porthcressa Bay for a last slow hour by the sea. It’s the best kind of final pause: a beach walk, a coffee, or just sitting with your feet up watching the water change colour. There are usually easy café options nearby in Hugh Town, and this is a good moment to pick up snacks or a drink for the onward journey if you haven’t already. Aim to keep this flexible — on Scilly, a little unplanned wandering is part of the point.
For the journey back to Edinburgh, plan to leave St Mary’s in the afternoon or early evening depending on your booked connection, with generous slack for boat timing, luggage, and any weather wobble. If you have time before heading off, grab anything you’ll want for the trip at a shop in Hugh Town and then make your way back to the departure point without rush; on departure day here, being early is always better than being precise.
