The Afan Portal of the Gyfylchi Tunnel, Afan Forest Park
There's a significant amount of Anthoceros punctatus to the right of the breeze-block-ed tunnel portal and on the right bank (approx. SS81709526). Not many 'horns' yet but the colony should be very photogenic in a week or so. Lots of Pseudephemerum nitidum and Fossombronia wondraczeckii/pusilla here too.

Access to this spot has been very difficult in the past, but there has obviously been a deliberate effort to clear the area recently. Given the proposal to convert the Rhondda Tunnel to a cycleway it is possible that similar developments may occur here. It is probably NRW managed land, so some measure of awareness and protection for the colony may be prudent.
