Regulars will be familiar with this museum but thought it was worth a mention for anyone who's new to Plakias or has not visited yet. We first went there in 2004 and again this year. It's one of those places where, the closer you look, the more there is to see. Not at all like most museums - the varied collection of items brings an earlier, simpler way of living, back to life. Some exhibits would benefit from English explanations/translations but the guy running the museum is never far away if you have questions. Entry is 2 Euro and, in my opinion, well worth it.
P.S. If you are keen on walking, we found the hills behind Asomatos easy to explore - the dogs guarding the sheep were all either friendly or safely behind a fence (some places we've been to, though, you see a dog tied up in the middle of nowhere guarding nothing )
