The most exciting activity while Charlotte was staying here was pond dipping. She found all manner of things - dragonfly larvae, damselfly larvae, baby newts, caddis fly eggs, pond skaters, whirlygigs to name but a few.This activity was organised by the rangers at the Elan Valley. Everything was provided, including the expertise of the rangers, it was completely free and at the end we were given a voucher for 10% off in the shop at the visitors centre.
