Valencia Smash International T20 (2017)
According to the official municipal event record, teams from the UK took part alongside Levante Cricket Club. The participating sides named were Freshfields CC, West Hagley CC, Cowley Drifters and Herts Vets CC.
This was a one-off documented event. It is not an annual tournament, and this website did not organise it.
Multi-club festivals
Several touring clubs visiting in the same window could, in principle, form a small festival. If your club is interested, mention it in your enquiry — it depends on venue availability and the interest of other clubs.
