Describe the access you need
Ask about the actual route your party will use. Relevant details may include steps, doorway width, path surface, distance from drop-off, seating and accessible toilets. Let the visitor decide which questions matter for them.
A venue saying it is “accessible” doesn't answer all of those questions.
Request concrete information
Ask for current photographs of the entrance and any difficult section if that would help the visitor assess it. Check whether an alternative entrance requires staff assistance and whether that staff member will be available.
If equipment or personal assistance is required, confirm what the venue provides and what you must arrange yourself. Don't assume a companion can safely improvise.
Choose a plan with a comfortable alternative
Discuss the information with the person attending before booking. If access remains uncertain, choose another activity rather than making them discover the problem on arrival.
Keep relevant arrangements in the private planning notes and share only what the visitor wants others to know. You can shortlist venues through Explore, but confirm accessibility directly for the date and activity you're booking.
Rules, fees and opening hours change. Confirm anything that matters before you rely on it.
