Title: $313 Cheap Flights to Merthyr Vale - Expedia.com ![#Details! .The Aberfan disaster was the catastrophic collapse of a colliery spoil tip in the Welsh village of Aberfan, near Merthyr Tydfil, that killed 116 children and 28 adults on 21 October 1966. The collapse was caused by the build-up of water in the accumulated rock and shale tip, which suddenly slid downhill in the form of slurry. In the cemetery side by side stands and overwhelming array of arches - each one a grave to those who passed that fateful day. It is beautiful and peaceful - almost heavenly - worthy of a visit....I felt initially uncomfortable to take photos but the beauty of it overwhelmed me and will live with me forever. #Photo Details Sweepstake](https://images.trvl-media.com/place/3000470116/86e5b213-27b9-4a77-909e-61f9ef1ea9df.jpg?impolicy=fcrop&w=1200&h=500&q=medium) Photo by Paula Evenden ![](https://images.trvl-media.com/place/3000470116/86e5b213-27b9-4a77-909e-61f9ef1ea9df.jpg?impolicy=fcrop&w=1200&h=500&q=medium) # $313 Cheap Flights to Merthyr Vale [View $313 flight on Wed, Nov 4, 2026](https://expedia.com/Flights-Search?trip=oneway&leg1=from:ECP,to:CWL,departure:11/4/2026TANYT&passengers=children:0,adults:1,seniors:0,infantinlap:N&mode=search&options=sortby:price&paandi=true&flp=mdl:flights-flex-module,price:312.30&airProductToken=AQqxAQo1CMSYARIEMTY3NBjEeCDgXCj5oJwDMMShnAM4RUAAWAFqCU1BSU5CQVNJQ3IIVkxYOTFTQkEKNAjEmAESAjcyGOBcIICTASj8pJwDMP-onAM4RUABWAFqCU1BSU5CQVNJQ3IIVkxYOTFTQkEKQgjEmAESBDk1ODAYgJMBIMJdKN6pnAMwrqqcAzhFQAFYAWoJTUFJTkJBU0lDcghWTFg5MVNCQXoKCMuYARIEMTA4NxIKCAEQARgBKgJETBgBIgQIARABKAIoAygEMAE) -
