Summer Splash Lido London 2026: London's Free Floating Lido

If you're looking for a way to cool off in London this summer without spending a penny, Summer Splash should be at the top of your list.

Returning to the Royal Docks from July 25 to August 17, 2026, Summer Splash transforms part of the historic docklands into a free outdoor swimming destination complete with lifeguards, a family-friendly swimming area, deckchairs, sandpits and daily activities. It is one of the few places in London where you can enjoy an open-air swim with skyline views without paying an entry fee.

Summer Splash is not a traditional lido. Instead, it is a purpose-built floating pool set directly within the Royal Docks. This offers a unique way to experience open-water swimming in the heart of the city while remaining in a controlled and supervised environment.

Whether you're planning a family day out, looking for a refreshing swim after work or simply want to enjoy London's waterfront during the warmer months, here's everything you need to know before you go.

What is it like swimming at Summer Splash?

The biggest difference between Summer Splash and most outdoor pools in London is the water itself.

Here, you'll be swimming in filtered dock water inside a purpose-built floating lido. The water is unheated, so it will be quite refreshing.. During late July and August, temperatures are typically around 18°C to 22°C depending on the weather.

The floating pool has been designed to make open-water swimming more accessible. Lifeguards supervise every session, and the pool includes a shallow section, making it suitable for families and less confident swimmers as well as experienced swimmers looking for an outdoor dip.

The setting is equally memorable. As you swim, you'll have views across the Royal Docks, City Hall and London's modern skyline, creating an experience very different from a traditional leisure centre.

Why does Summer Splash stand out?

Summer Splash is designed as a place where you can spend several hours.

Surrounding the pool you'll find deckchairs where you can relax after swimming, sandpits for younger children and open spaces where families can spend the afternoon.

Daily activities are scheduled throughout the event. Family-friendly sessions take place across the site. There are also supervised swim-safe programmes. These are designed to introduce people to outdoor swimming in a safe environment.

The relaxed atmosphere is one of the biggest reasons people return every year. You can swim, relax by the water and have a lazy day out at the Royal Docks.

At The Docks 2026 has much more to explore

Summer Splash is only one part of the wider At The Docks programme.

Throughout the summer, the Royal Docks become one of London's biggest outdoor activity hubs, with a packed calendar of sports, entertainment and waterfront experiences.

If you're planning a full day out, you can also try:

• Paddleboarding
• Wakeboarding
• Open-water swimming
• Family workshops
• Live entertainment and seasonal events

Some of these activities require advance booking or separate payment. Together, they make the Royal Docks one of London's most active waterfront destinations during the summer holidays.

What makes the Royal Docks worth visiting?

The Royal Docks are one of London's most historic waterfront districts.

Originally developed during the Victorian era as part of London's global trading network, the docks have since been transformed into a modern public space that combines historic architecture with contemporary attractions.

Today, the area is home to City Hall, ExCeL London, waterside cafés, public art and wide pedestrian walkways overlooking the docks.

Even if you don't plan to swim, it's an enjoyable place to spend a summer afternoon. Summer Splash simply gives you another reason to visit.

How to get to Summer Splash

The floating lido is located beside City Hall at the Royal Docks in East London.

• By DLR: Docklands Light Railway to Royal Victoria Station, then a short walk to the pool.
• By Elizabeth line: Travel to Custom House Station, which is within walking distance.
• By Jubilee line: Change at Canning Town, then take one stop on the DLR to Royal Victoria.
• By Cable Car: From south London, take the IFS Cloud Cable Car across the Thames to the Royal Docks for a scenic arrival.
• By Car: Use nearby ExCeL London parking facilities, though public transport is recommended during busy summer weekends.

Tips before you go

Summer Splash operates for a limited time, so it is worth planning your visit before the closing date on August 17, 2026.

• Weekdays are generally quieter than weekends, particularly during the morning.
• Because the water is unheated, bring a towel and a change of clothes even on warmer days.
• Sunscreen is still essential, especially if you're planning to spend time relaxing in the deckchairs after your swim.
• If you're visiting with children, arrive early enough to enjoy the sandpit, family activities and the wider Royal Docks programme alongside your swim.
• Checking the official Royal Docks website before travelling is also recommended, as daily activities and event schedules can vary.
