The last adder I saw was about 20 yrs ago, & I've never been bitten by one, despite living in the country most of my life. As long as a walker is making plenty of noise (heavy footsteps), any adders will move out of the way before they are seen. The main exception to this is when they are sunning themselves to warm up to full operating temperature early in the day. Adders, being cold blooded are quite lethargic until the sun warms them and then they can be too slow to move before they are seen, then they may strike out in defence. The last one I saw was lying on a grassy bank in the sun on a chilly April morning - my dog spotted it, but the adder hadn't even warmed up enough to move away, so it was left in peace.
