April London has the parks blooming, the weather behaving, and the summer crowds not yet arrived.
One of the genuinely excellent months to visit London. The Royal Parks are spectacular, the weather is mild and often sunny, and crowds at major attractions are manageable. Easter weekend brings a spike but the rest of April is ideal for sightseeing. Book the Tower of London and British Museum with skip-the-line tickets; queues are back but not summer levels.
