🚗Do we need a car in St Mary's? Is it worth it? Should we rent one? | Comment
St Mary’s is the largest island in the Isles of Scilly, but by almost any standard it is very small, calm, and slow-paced. Distances are short, traffic is minimal, and the appeal lies in beaches, coastal walking, and island life rather than moving around a lot. That leads to a refreshingly simple question: should you rent a car on St Mary’s 🤔.

Here, the answer is always no.


🚫 Why You Don’t Need a Car on St Mary’s

St Mary’s is easily walkable end to end 🚶‍♂️.

Most accommodation, beaches, cafés, shops, and the harbour in Hugh Town sit close together ⏱️.

The island has very few roads, very little traffic, and a relaxed pace that actively discourages driving 🌿.

Bikes and electric buggies are far more common than cars 🚲.

For visitors, a car would mostly sit unused.


🚗 Is There Any Point Renting a Car?

In practical terms, no 🚗❌.

Car rental options are extremely limited, and visitors are not encouraged to bring vehicles to the islands.

The few vehicles you’ll see are mainly used by locals, services, or delivery operations.

Even the island’s furthest beaches are only a short walk or cycle away.


🚲 Alternatives: Walking and Cycling

Walking is the default way to explore St Mary’s 🚶‍♂️.

Cycling is popular and well suited to the island’s scale 🚲.

There’s no need for public transport, because distances are simply too short to justify it.

This is one of the rare UK destinations where not having a car is clearly an advantage.


🚆✈️ Getting to St Mary’s

St Mary’s is served by St Mary’s Airport (ISC), with flights from the southwest of England ✈️.

Many visitors also arrive by ferry from Penzance, docking directly at Hugh Town harbour ⛴️.

Once you arrive, no onward transport is really required.


🧾 Conclusion: should you rent a car on St Mary’s?

No — and that’s part of the appeal.

St Mary’s is designed for walking, cycling, and slowing down, not driving.

So, should you rent a car on St Mary’s (ISC)?
❌ No — for virtually all visitors.
