Marine lake

Wellington Road
LL18 1AQ 

Sailing, canoeing, waterskiing, wakeboarding, kneeboarding and for those of you that are daring enough; barefooting. These are just some of the activities you can take part in at Marine Lake, the only salt water lake in North Wales. 12 hectares in size, Marine Lake is a man-made reservoir next to the mouth of the River Clwyd. 

For those who don’t like to get wet, have a walk round the Lake taking in our new Environmental Trail, spot some of the wildlife, or have a ride on the Miniature Railway, the oldest in the UK and operated by Rhyl Steam Preservation Trust.

Marine Lake timetable 


There are rules depending on how you want to use the Lake. All users will need the following to use Marine Lake: 

  • Insurance 
  • Lifejackets or buoyancy aids 
  • Permit

Water–skiing and wake-boarding

Power boat owners may use Marine Lake providing that they become a member of Ocean Beach Water Ski Club. This is to enable a mentored induction to the lake prior so that we know your competent and familiar with how Marine Lake operates. Once you’ve got proof of membership, a valid public liability insurance certificate is needed and payment made, to get your permit, boat sticker and slipway key. The use of Personal Water Craft (Jet Ski’s) is forbidden on Marine Lake. A copy of the operating procedures for Marine Lake will be issued with your permit, and these must be adhered to at all times.

Non-Power Sailing

Canoe, Kyak, Wind Surf and Sail boat owners are welcome to use Marine Lake. As with power vessels, a valid insurance certificate must be produced and payment made before a permit and boat sticker is issued.

There is no skiing or power activity, only sailing / non-powered from October – March. This is through discussion with the Marine Lake Users Forum, as we don’t want to disturb the wildlife that uses the island during these months.
