I travelled with my family, wife Natalia and children Alexander 13 and Nina, 10, from Copenhagen airport with Solresor on a combined vacation and birding trip. We stayed at the very calm and well situated hotel Panorama at the northern part of village Petra. When staying at this hotel it is recommended to have a room in the more higher situated cottages with beautiful views over Petra.
We rented a 5-door Fiat Punto with AC in advance at https://www.economycarrentals.com. I used the Freytag & Berndt 1:75 000 map over Lesvos, but found on Lesvos the possibly better Lesbos Road Edition 212 1:70 000. Essential in the preparation of the trip was the excellent Birding on the Greek Island of Lesvos by Richard Brooks with plenty of very useful maps.
The weather was sunny all days with just light skies in one morning. Temperatures ranged from just above 20 degrees early in the mornings to just below 30 in the afternoons. In all 78 species of birds were seen.
