Counties 3 Somerset
Counties 3 Somerset is an English rugby union league which sits at the ninth level of league rugby union in England involving teams based in the county of Somerset as well as some teams based in Bristol. 1st, 2nd and even 3rd XV sides can participate in the division as long as they are not from the same club.
