- Why this month: April is one of London's best flower months, especially for tulips, magnolias, and fresh spring colour.
- Best time: 10am–1pm
- Book by: 3–7 days ahead for warm weekends
- Crowds: Moderate
- Kew is big enough to absorb people, and the plantings feel properly seasonal rather than generic-park pretty.
- Don't miss: Long spring borders and the wider sweep of colour near the formal gardens
- Insider tip: Go on a weekday if you can; weekend trains to Kew get busier once the forecast turns sunny.
