Information you can follow.

Research here means checking information used in our visitor guidance and cultural writing. It does not mean that Apollonaut runs a laboratory, employs an academic research department or has completed original scientific studies.

For opening hours, admission and visitor rules, the first source is Chester Zoo’s own website and its terms and conditions. For the zoo’s history we used general references that cite their sources. All can be read directly through the links provided.

1. 01

   Start with the relevant source

   Use the venue for its own visitor rules and history. Use an identified reference for dates, architecture and institutional facts.

2. 02

   Keep time-sensitive details dated

   Prices, opening hours, holiday closures and eligibility can change. A past arrangement or old tariff must not become a current promise.

3. 03

   Separate fact from interpretation

   A sourced date is different from an editorial impression. Make the distinction clear in the writing.

4. 04

   Keep uncertainty visible

   If sources disagree or a detail is unverified, omit the claim or explain the limit. Published counts of the zoo’s animals and its area differ, so we give no animal count and use the zoo’s own figure for its size.

A starting price, a venue admission price and the total charged for a booking are different figures. A useful comparison must identify the same access, visitor category, date, currency and included fees.

Our prices are in British pounds and include our service fee, so they are higher than Chester Zoo’s own admission prices. We do not claim the lowest price or publish a market comparison.

• How our service works→

The aim is to make source links and meaningful updates easy to find. A material correction should explain what changed rather than quietly leaving contradictory information elsewhere on the site.

The heritage and history copy was checked against the reading links below on 10 November 2026. This date records that review; it is not a guarantee that future opening hours or admission rules will remain the same.
