The Simms

A Simm is a hill in England, Wales or Scotland over 600m high with a drop of at least 30 metres all round.  Simm is an acronym for Six-hundred Metre Mountain.  The Irish and Isle of Man Simms are also listed on this website.

A Subsimm is a hill which just fails (by up to 10m) to qualify on the drop rule, i.e. over 600m with 20-29m drop.

(Simms appear as Class=Sim on this website, and Subsimms as Class=sSim).

My Progress
I have completed 0 (0%) of 2528 Simms of Britain [Map*]
0 (0%) of 2188 Scottish Simms [Map*]
0 (0%) of 192 English Simms [Map*]
0 (0%) of 150 Welsh Simms [Map*]

0 (0%) of 1 Manx Simms [Map*]
0 (0%) of 224 Irish Simms [Map*]

The discrepancy in the totals is due to 2 hills on the Scotland/England border which are included in the totals for both countries.
