The questions people actually arrive with.
Each college sets its own visiting hours and several charge entry. Many close entirely to visitors, and the porters at the gate are the authority on it.

Most Cambridge colleges restrict public access to certain hours, typically afternoons only (12:00-15:00 or 14:00-16:30). Several charge entrance fees (£5-15). Some colleges close entirely on certain days. Access to chapels, libraries, and gardens varies. The colleges are working academic communities, not museums — visitors must respect this.
Check each college's website for opening times before you go. Visit in the early afternoon for the best access. Budget £5-15 per college for entrance fees. Don't try to sneak in — porters will turn you away.
All 31 Cambridge colleges, particularly Trinity, St John's, King's, Queens', and Clare.
Exam term shuts most colleges to visitors, including King's. If you are coming for the architecture, this is the wrong six weeks.

Most colleges close entirely to visitors during the exam period, roughly mid-May through late June. This is called the 'Easter Term' exam period. Even colleges that normally welcome tourists shut their gates. King's College Chapel may remain open but with reduced hours.
Avoid visiting Cambridge specifically for the colleges between mid-May and late June. If you do visit, focus on the Fitzwilliam Museum, Botanic Garden, punting, and the city's restaurants and shops instead.
All Cambridge colleges. The entire city center is noticeably quieter as students focus on exams.
Self-hire is legal and the Cam is shallow. The touts on the bridges are aggressive and unlicensed ones do operate — book at a boatyard.

Punting is Cambridge's signature activity, but self-hire can be tricky for beginners — the poles get stuck in the muddy riverbed, collisions with other punts are common, and falling in is a rite of passage. Unlicensed punt operators sometimes overcharge tourists, especially near King's College and Silver Street Bridge.
Book with a licensed operator like Scudamore's or the official college punt companies. If self-hiring, get a proper tutorial first. Push from the Cambridge end (standing at the back of the punt). Budget £25-35 per hour for self-hire, £18-25 per person for chauffeured tours.
River Cam — main punting stretch from Silver Street Bridge to Grantchester, and the college Backs.
The lawns belong to the colleges and are not public park. Fellows' lawns in particular are for fellows, which is not a joke to the person asking you to leave.

The Backs are the beautiful green areas behind the riverside colleges (King's, Clare, Trinity, St John's, Queens'). While some paths are public, many areas are private college grounds. Straying off designated paths onto college lawns or entering private gardens can result in being asked to leave by porters or receiving a trespass warning.
Stick to the public paths along the river and Queen's Road. Don't walk on college lawns or enter gates marked 'Private' or 'College Members Only.' The best views of the Backs are from the river — take a punt for the full experience.

13 Cambridge rules
Highest risk first. Open any row for the detail. 1 more comes from United Kingdom law — listed below.
Cambridge has a Public Spaces Protection Order (PSPO) that allows police and council officers to confiscate alcohol and issue fines in designated zones. The PSPO covers most of the city center, parks, and the riverside. You won’t be fined for having a quiet drink by the river in practice, but anti-social drinking is actively targeted. The statutory position: s. 68 of the Anti-social Behaviour, Crime and Policing Act 2014 caps the fixed penalty at £100, and if the matter goes to court instead the fine can reach level 3 on the standard scale, £1,000.
City center PSPO zone including Market Square, Parker's Piece, Jesus Green, Midsummer Common, and the riverside.
Anti-social Behaviour, Crime and Policing Act 2014 ss. 67-68; Sentencing Act 2020 s. 122.
A quiet picnic with wine by the Cam is generally tolerated, but loud or anti-social drinking will attract enforcement. If asked by an officer to stop drinking, comply immediately — refusing is the actual offence that triggers the fine.
Dropping litter including cigarette butts and chewing gum carries a fixed penalty notice. Cambridge is a historic and well-maintained city, and enforcement is active, particularly around the colleges, Market Square, and green spaces.
All public areas. Especially enforced around the colleges, Market Square, Parker's Piece, and the Backs.
Environmental Protection Act 1990; Cambridge City Council enforcement policy.
Use the bins — they're plentiful in central Cambridge. If bins are full, carry your rubbish to the next one. Cigarette butts count as litter.
Cambridge is the UK's number one cycling city. Bikes outnumber cars in the city center. Cyclists are everywhere — on roads, shared paths, and cutting through pedestrian areas. As a pedestrian, being hit by a cyclist is a genuine risk if you step into cycle lanes without looking. As a cyclist, you must follow UK road rules.
Entire city, particularly the cycle lanes on Hills Road, Trumpington Street, and around Parker's Piece. College entrances and narrow streets are especially hazardous.
Cambridgeshire County Council cycling guidance; Highway Code.
Always look both ways before stepping off a pavement — check for bikes, not just cars. Don't walk in marked cycle lanes. If cycling, use lights at night (legally required), don't cycle on pavements, and lock your bike securely — theft is rampant.
Excessive noise near college buildings can result in complaints to police, especially during the exam period (May-June) and after 11pm year-round. Buskers must follow licensing rules and avoid certain areas. Student-heavy areas like Mill Road have noise-sensitive zones.
Near all college buildings, particularly during exam season. Residential streets around colleges. King's Parade and Senate House Passage.
Cambridge City Council noise policy; university regulations.
Keep voices down when walking past colleges, especially in the evenings. Don't shout or play music near college walls. During May-June exams, be extra considerate.
Cambridge actively discourages driving into the city center. There are very few city-center car parks and they fill early. Parking on yellow lines, in resident zones, or overstaying at meters results in penalty charge notices. Some areas have ANPR cameras. The Park & Ride system is the intended alternative.
All city center streets and car parks. Resident parking zones throughout central Cambridge.
Cambridgeshire County Council parking enforcement; Cambridge City Council transport policy.
Don't drive into Cambridge. Use the Park & Ride service from one of five sites around the city (Trumpington, Babraham Road, Newmarket Road, Milton, Madingley). If coming from London, take the train — it's 50 minutes from King's Cross.
Cannabis is a Class B drug in the UK. Possession can result in up to 5 years in prison, an unlimited fine, or both. Supply and production carry up to 14 years. Police can issue warnings for small amounts but this is at their discretion. Unlike some European countries, there are no tolerance zones or decriminalisation policies in the UK.
Everywhere in Cambridge and the UK. Enforcement is active around the university and in public spaces.
Misuse of Drugs Act 1971; UK Home Office drug classification.
Do not buy, carry, or use cannabis anywhere in the UK. Even small amounts for personal use can result in arrest and a criminal record that could affect future travel.

King's College Chapel is Cambridge's most famous building and charges an entrance fee (£11 adults). Photography is allowed for personal use but flash photography and tripods are prohibited. During choir services and evensong, no photography is permitted at all. Talking during services will result in removal.

Despite the name, 'May Week' takes place in June, after exams end. Colleges host May Balls and garden parties — elaborate black-tie events with tickets costing £150-350+. During May Week, some college grounds and surrounding streets have restricted access, increased security, and noise. Some areas near colleges may be fenced off.
Various colleges throughout Cambridge, particularly Trinity, St John's, Clare, King's, and Queens'. Streets around hosting colleges may have temporary restrictions.
University of Cambridge; individual college May Ball committees.
Check if May Week events coincide with your visit (usually mid-to-late June). Some college areas will be inaccessible. The atmosphere is festive but may affect your sightseeing plans. May Ball tickets are generally only available to students and their guests.
Since 2025/2026, non-EU visitors from visa-exempt countries (including the US, Canada, Australia, and others) require an Electronic Travel Authorisation (ETA) to enter the UK. The ETA costs £16 and must be obtained before travel. It is linked to your passport and valid for multiple visits over 2 years. EU and Irish citizens do not need an ETA.
Required before arrival in the UK — you may be denied boarding or entry without one.
UK Home Office; Nationality and Borders Act 2022; UK ETA scheme.
Apply for your ETA online through the UK ETA app or website well before your trip. Processing usually takes a few days but can take longer. Keep confirmation on your phone. The £16 fee is non-refundable.
