Worms, bugs and bats feature in children’s holiday events at Holland Park Ecology Centre. Beetle Mania is a good workshop, lots of beetles to look at and the children make a beetle model too. One of the most popular ones in Survivor, where children build a shelter in the park. These are incredibly well-run and interesting but to qualify you have to be between five and 10 years old and it only costs £4.10 for a two hour session. www.rbkc.gov.uk Meeting place for all the activities is the Ecology Centre, next to the adventure playground. 14th-25th April and you must book.
