ARRAN'S WEE GREEN TRAVEL MAP
Arran Eco Savvy has created these informative maps for the island, you can download the PDF in the link below.
The only (mostly) flat routes from Brodick are to beautiful Glen Rosa and North as far as the beach at Sannox. Anywhere further is VERY HILLY and not for folks who don't love climbing steep inclines.
With an ebike, however, the hills won't bother you! Its still a trek if you want to tackle the whole island but infinitely more manageable than with an ordinary pushbike.
