As my trip gets closer, I am now planning the specific details and am looking for recommendations for biking the Greenway. The 42km full length is too long for me. What part of the Greenway would you say is can't-miss and the most scenic? Westport-Newport? Newport-Mulranny? Mulranny-Achill? Maybe Mulranny-Achill-Mulranny? Also, how difficult is the terrain in each section? Another question: has anyone heard anything about electric bike rental so I could increase the distance I could cover and maybe do the whole Greenway? I see that one Westport rental place offers one. I have researched the bike rental places with websites and think I have a pretty good understanding of them, but I would love any insider insight you could share, especially for the ones that are not online!!! Thanks so much!
