In reply to Jus:
Hi
Although they'd grown up by the time I'd discovered Kalymnos, I'd nevertheless taken my kids to crags across Europe/the States since they were 6 months old. On the basis of this, here's my view:
Most Kalymnos crags are not as easy for kids as, say, somewhere like Mouries North Face which has, basically, a cricket pitch at its base! Approaches at Kaly tend to be quite steep and rocky (even if mainly short) so a 2 year-old would need some attention and help on the way up and down. Although virtually every crag has some flat ground, the terrain usually leads away quickly into prickly scrub, rocky slopes and small craglets... if small children wandered off, they would almost inevitably gather grazed knees and their yowls and your guilt would blow your red points.
Also as many of the crags are tufa-rich, one can not afford to be inattentive and children would either need to be tucked under a protective overhang/in a small cave or positioned WELL outside the fallout zone of dislodged rock. Groundward tufa does explode over a large distance. Although one does see some pretty thoughtless people with children on occasion, this is REALLY important in a place like Kaly. Without a third party, it's very unlikely that a 2 year-old would stay in a 'safe' location for long (boredom sets in). For this reason, I would have felt very uncomfortable taking a 2 year-old if there'd only been 2 adults in the team.
However with a third person, it's entirely possible to take a 2-year old to virtually all crags on Kaly... and many many families do. Often it seems to be two couples with kids and days alternate between beach teams with all the kids and climbing teams without. If that's possible, then Kalymnos is one of the very best locations for a combined family/beach/climbing holidays. Just be alert to the dangers.
I also believe it's possible to get child minders... phone Birgitta at the Kalymnos Adventure Center.
