Cold Water, Open Sky: Edinburgh's Outdoor Pools and Rock Pools Perfect for Lap Swimming

Edinburgh has a cold-water swimming problem — not enough of it, according to the growing crowds turning up at Portobello Beach before 7am on weekday mornings. Wild swimming has moved well past trend status here. It is now a fixture of the city's fitness calendar, and the question local swimmers are increasingly asking is where, exactly, they can get a proper lap in without booking a lane at the Royal Commonwealth Pool.

The timing matters. A parliamentary push is underway across Britain — backed by Labour MPs at Westminster — to reverse decades of lido closures and restore outdoor public pools to urban communities. Edinburgh sits at an interesting juncture: it has coastline, lochs within reach, and a genuine appetite for cold-water fitness, but purpose-built outdoor lap facilities remain thin on the ground. What the city does have, for those who know where to look, is a scattered network of natural and semi-natural spots that experienced swimmers have quietly claimed as their own.

Where Edinburgh Swimmers Actually Go

Portobello, the seaside neighbourhood four miles east of the city centre along the A1199, is the obvious starting point. The beach itself offers open-water swimming at any tide, but the more interesting spot for anyone seeking structure is the stretch of flat rock shelf near the Victorian-era promenade, where low tide reveals a series of natural rock channels wide enough for a controlled swim. These are not manicured lido lanes. Footing is uneven, currents shift, and water temperature in early July typically sits around 13 to 14 degrees Celsius — bracing enough to require a wetsuit for beginners.

Cramond, on the Firth of Forth at the western edge of the city, draws a different crowd. The tidal flats near Cramond Island offer calmer, shallower water that some swimmers use for short laps parallel to the shore. The walk from Cramond Brig along the River Almond to the estuary is itself part of the appeal — roughly 1.5 miles one way, making the swim-and-walk combination a complete morning workout. The Cramond Inn at the river mouth serves as an informal gathering point for open-water regulars who coordinate via community channels run through Edinburgh-based groups including Swimhike Scotland, which organises guided outdoor swims across the Lothians throughout summer.

The Warrender Swim Centre in Marchmont, operated by Edinburgh Leisure, offers the city's nearest indoor alternative to a lido — a 25-metre pool with a long history dating to 1887 — but outdoor provision through Edinburgh Leisure itself remains limited. A day swim pass at most Edinburgh Leisure facilities runs around £5.60 for adults as of summer 2026, though this covers indoor pools only.

What a Proper Outdoor Pool Would Mean for the City

The lido revival conversation is no longer abstract. Across Britain, campaigners and local authorities are examining feasibility studies for restored outdoor pools, with examples like the Brockwell Lido in London and Stonehaven Open Air Pool in Aberdeenshire — the latter just 90 miles up the A90 from Edinburgh — demonstrating that heated outdoor pools can be commercially viable outside peak summer months. Stonehaven's pool, built in 1934, reopens each May and uses solar-assisted heating to extend its season into September.

Edinburgh's own lido history is largely demolished. The Portobello Open Air Pool, which once held up to 6,000 spectators at swimming galas, closed in 1979 and was torn down in 1988. The site near the promenade is now a car park. Community campaigns to revisit outdoor pool provision in the area have surfaced periodically, though no funded project is currently in development.

For swimmers who cannot wait for a policy shift, the practical advice is layered preparation. Water safety charity Swim England recommends never swimming alone in open water and always checking tide tables before entering coastal spots like Portobello or Cramond. Waterproof tow floats — available from most Edinburgh outdoor retailers including Tiso on Rose Street — cost between £20 and £45 and are considered standard kit for solo swimmers. July and August offer the longest safe swimming windows, with dawn light arriving before 5am and water temperatures at their annual peak. Cold-water acclimatisation, ideally started in May, makes a significant difference to both safety and endurance by midsummer.
