Daw’r ymweliad wrth i Wythnos Twristiaeth Cymru 2019 ddirwyn i ben ac wrth i ffigurau Baromedr Busnes Twristiaeth Cymru gael eu cyhoeddi heddiw, sy'n dangos bod y diwydiant twristiaeth wedi cael Pasg ardderchog.
The visit comes as Wales Tourism Week 2019 draws to a close and as figures from the Wales Tourism Business Barometer are published today, which show the tourism industry had an excellent Easter.
