River swimming / jumping. Kids have been jumping off bridge into a deep pool on downstream side for decades. We've been going for last four years.
Very gentle flow and easy access via grassy bank for the less adventurous!
Come into the village of Meifod on the A495 from either direction and look out for the signpost for Clwb Cobra / Cobra Rugby Club. Road bridge crosses Vyrnwy, park where you can and make your way to upstream side of bridge via stiles for grassy bank access to river.
