Footpath surveys are being held by the Pembrokeshire Coast and Brecon Beacons national park authorities, aimed at finding out whether the way the rights of way systems operate are serving the needs of users as well as they should.
Those who like to go walking
, ride mountain bikes
or put on horse riding clothing
may all be among the users keen to have their say.
Pembrokeshire Coast National Park Authority chairman Councillor Tony Brinsden said he wanted to hear people's views "whether you walk a stretch of the 186-mile Pembrokeshire Coast Path - one of the world's finest long-distance trails - or you head inland for a stroll".
The information gathered will be used to assess the priorities of the national parks, he added.
While the Pembrokeshire Coast covers more of the coastline than all the other national parks in Britain put together, the Brecon Beacons contains the highest mountains in the southern half of Britain, topped by Pen y Fan at 2,906 ft.
