Access & arrangements

Swimming is permitted only in designated areas during pre-booked organised sessions. Confirm eligibility and session availability with Welsh Water.

Keep in mind

Unauthorised reservoir swimming is prohibited. Hidden machinery and deep cold water make the managed-session boundary essential.

Access & arrangements

NRW permits swimming from its car-park side, subject to restrictions. The north end is private; consult the on-site water-use panel.

Keep in mind

Llyn Tegid

Bala, Eryri · Coast & lake shores

A mountain-framed lake with detailed National Park swimming guidance and a named foreshore contact for checking local arrangements.

Access & arrangements

Read the authority's swimming guidance and on-site zoning. Organised events require separate arrangements; do not confuse other watersports permits with swimming rules.

Keep in mind

Cold water, rapidly changing weather, other lake users and occasional algae warnings require separate checks before a visit.

Public pay-and-display car parks and a lake warden office/contact are identified by the National Park.

Check lake warden algae notices; no routine designated bathing-water coverage is assumed here.

Tenby, Pembrokeshire · Coast & lake shores

A town-backed sandy beach with a promenade and an identifiable RNLI information page, offering a different setting from remote coves.

Access & arrangements

Check current beach signs, tide conditions and RNLI patrol dates. Summer patrols are limited rather than a promise of daily cover throughout the year.

St Davids, Pembrokeshire · Coast & lake shores

A distinctive St Davids peninsula beach with a clear RNLI patrol page and visitor information about its surfing setting.

Access & arrangements

Check current RNLI patrol dates and on-site flags. Patrol arrangements can change, and no flags means no lifeguards.

Keep in mind

This is an exposed surfing beach with changing sea conditions; seasonal lifeguard cover does not make every part suitable for swimming.

Visit Wales lists a cafe and toilets near the car park; check opening and transport arrangements before travelling.

Find the Whitesands bathing-water profile and current notices; do not treat annual classifications as live readings.

A town-connected beach with a promenade and council visitor information, giving the shortlist a practical resort-coast option.

Access & arrangements

Follow beach signs, designated swimming areas and current seasonal restrictions. The northern end is bounded by the harbour.

Keep in mind
