Mastering London's transport for stress-free movement
Essential Arrival Protocols and High-Altitude Skyline Shortcuts
Navigating London now requires navigating digital borders before you even land. The most significant shift is the mandatory Electronic Travel Authorisation (ETA), a 'no permission, no travel' system required for all visa-exempt visitors. Ensure this is approved at least 72 hours before departure to avoid boarding denials at the airport. On the ground, the hierarchy of free views has shifted; while the Sky Garden remains iconic, Horizon 22 at 22 Bishopsgate now stands as the city's highest free viewing gallery, offering unobstructed 360-degree vistas that surpass the Shard's public levels. Slots for this and the nearby 'Lookout' gallery open on a rolling basis and are essential for your itinerary. For transit, the legacy Oyster card is largely obsolete for adults; using a mobile wallet or contactless card provides the same daily price caps without the non-refundable deposit fees, though families with children aged 11–15 should still seek out a Visitor Oyster to access the mandatory 50% Young Visitor discount which cannot be applied to standard bank cards.

Hidden shortcuts and local alternatives to tourist hotspots
Yes, most international visitors who do not require a visa, including those from the US, Canada, and the EU, must obtain an Electronic Travel Authorisation (ETA) before traveling to the UK in 2026. This digital permit is checked at boarding, and failure to have an approved status will result in being denied entry to your flight or train.
For most adults in 2026, contactless payment (via credit card or mobile wallet) is superior to the Oyster card as it requires no deposit and automatically applies the best daily and weekly price caps. However, families with children aged 11–15 should still use an Oyster card to benefit from the 50% 'Young Visitor' discount, which is not available on contactless cards.
In 2026, Horizon 22 is the premier choice, currently holding the title of the highest free viewing gallery in Europe. While the Sky Garden is more famous, Horizon 22 offers a higher perspective and more frequent slot releases. Both require booking several weeks in advance through their respective official websites to guarantee entry.
