Leave Heathrow by around 11:00 AM via the M25, A303 and A30, allowing roughly 5–6 hours to Land’s End—and longer on this August Friday if traffic builds around the A303, Exeter or Bodmin. Stop for fuel and a proper break before the final stretch; services become less frequent west of Penzance. On arrival, check in at your campsite near Land’s End, unload, and keep valuables out of sight while you head out again. If the drive runs late, shorten the coastal stops rather than rushing them.
Spend about 1½ hours at Land’s End, walking from the visitor centre towards the cliffs and the famous signpost. The headland is free to explore, although the main car park is typically around £8–£10 for the day; the visitor-centre facilities and shops generally remain open into the late afternoon, but check the seasonal closing time on arrival. The cliff paths are exposed, so bring a waterproof layer and sturdy shoes—even in August—and stay well back from the edges. From Land’s End, drive approximately 15–20 minutes to Porthcurno, following signs through Sennen and Treen.
Use the early evening for a relaxed hour or so at Porthcurno Beach, one of Cornwall’s most striking coves. Parking is limited and can fill quickly; the car park usually charges roughly £5–£8, and access from the lot involves a short downhill walk. Check the tide and leave enough daylight for the uphill return, as the lane is narrow and poorly lit after dark. For dinner, drive about 5 minutes to The Logan Rock Inn in Treen, a welcoming village pub where mains are usually around £20–£35 per person. Booking is wise on a Friday in August, and arrive before the kitchen’s final orders—often around 8:30–9:00 PM.
After dinner, allow roughly 15–20 minutes back to your campsite near Land’s End. Set up before it becomes fully dark, keep food sealed against gulls and wildlife, and check the next morning’s tidal access arrangements before turning in.
From your campsite near Land’s End Airport, drive east to Marazion in roughly 35–45 minutes via Penzance and the A30/A394. Set off around 8:00 AM: summer traffic builds quickly, and parking in Marazion is much easier before mid-morning. Visit St Michael’s Mount for about three hours, checking the official tide timetable before leaving. At low tide you can walk the causeway; when it is covered, use the small passenger boat if operating. Castle and island-village admission is usually around £15–£20 for an adult, with access subject to opening times and weather.
Afterwards, spend 45 minutes at Marazion Beach, where the broad sand gives the classic view back towards the mount. It is worth walking a little east along the shore rather than staying beside the busiest access point. Keep an eye on bags and footwear if you are tempted into the water—the beach is tidal, and there are no guarantees of lifeguard cover across its full length.
Continue west for about 15 minutes to Jubilee Pool in Penzance. Have lunch nearby at The Shore Restaurant, The Front Room, or one of the cafés around Chapel Street, then allow roughly 1½ hours for a swim in the art-deco seawater lido. Advance booking is sensible in August; admission commonly falls around £10–£15, depending on the session, and you should bring a towel, changing layers, and sandals for the concrete pool surrounds. From Penzance, drive to St Ives in 25–35 minutes, but consider parking at St Erth and taking the scenic branch train if traffic is heavy; central St Ives parking fills rapidly.
Wander St Ives Harbour for an hour, following the narrow lanes around Fore Street and Wharf Road before visiting Tate St Ives. Allow 1½ hours for the galleries and lookout over Porthmeor; admission is generally about £15–£18, with seasonal opening often extending into the early evening, though check the current closing time. Finish at Porthmeor Beach Café around 6:30 PM for a sunset-facing dinner—reserve ahead for an outdoor table, and expect approximately £20–£40 per person. After dinner, drive back to your campsite near Land’s End Airport in about 35–45 minutes; leave St Ives before full darkness if you are unfamiliar with Cornwall’s narrow lanes.
Start at Fistral Beach around 9:00 AM, before the main summer crowds and while the beach is at its liveliest. Allow about two hours for a cliff-top walk, a swim, or a beginner surf lesson; several local surf schools operate from the beach, but pre-booking is sensible in August. Check the tide and surf forecast, bring a towel and warm layer, and use the public toilets and cafés near the car park. Parking fills quickly, so arrive early; expect roughly £2–£4 for short-stay parking, depending on the season and length of stay.
Walk or drive into central Newquay for Newquay Harbour, about 15–20 minutes on foot from Fistral. Spend 45 minutes around the harbour and headland, watching the fishing boats and looking back along the rugged coastline. At around 12:30 PM, have lunch at The Harbour Fish & Grill, where seafood mains generally cost £20–35 per person; book ahead or arrive promptly, as August tables disappear quickly.
After lunch, drive or take a taxi to Newquay Zoo in Trenance—roughly 10 minutes by car, with parking available nearby—and allow about 2½ hours for the exhibits and landscaped paths. Check the zoo’s exact closing time before setting out; summer hours are typically around 10:00 AM–5:00 or 6:00 PM, with adult admission commonly in the £18–£25 range when booked online. Keep the late afternoon unhurried with a walk through Trenance Gardens, following the River Gannel and wooded paths for about an hour. Finish at The Fort Inn for dinner, a relaxed Newquay pub with sea-facing views; allow £20–35 per person, and reserve a table if you want the best evening outlook.
Leave your Newquay campsite around 7:30 AM so you can reach Tintagel Castle shortly after opening, when the clifftop paths are quieter and parking is easier. Use the main village car park on Bossiney Road—it is about a 10–15-minute walk from the castle entrance and fills quickly in August. Allow roughly 2½ hours for the ruins, island bridge and steep descent toward Merlin’s Cave; wear proper shoes, as the coastal steps can be slippery and the cave is accessible only around low tide. Timed tickets are strongly advisable, with adult admission typically around £20–25; check the official opening time and tide conditions before leaving.
After the castle, spend about 45 minutes at Tintagel Old Post Office, a National Trust medieval building just off the village’s Fore Street. It is a compact visit, so keep an eye on the clock and aim to drive to Boscastle Harbour by late morning—roughly 15 minutes along the A39. Wander the harbour, stone quay and short cliff paths for about 1½ hours, keeping clear of the exposed edges in windy weather. For lunch, settle into The Cobweb Inn on Fore Street, a characterful old pub serving traditional dishes for approximately £18–30 per person; August tables fill quickly, so arrive early or call ahead.
Leave Boscastle by about 2:30 PM—this is the key departure time if you need to reach London by 9:00 PM. Refuel before joining the A30, then follow the A30 toward Exeter and continue via the M5 and M4; allow 5½–7 hours with a proper break, and expect heavier holiday traffic around Exeter, Bristol and the M4. Keep the car stocked with water and snacks, and do not rely on making up time later: a short stop at a motorway services is more realistic than another sightseeing detour. If returning the rental car in London, confirm the exact drop-off location and late-opening arrangements in advance, allowing extra time for parking and the final approach into the city.
