I spent six weeks on Kumay going round the planet starting and ending at Bridger Town during the First Great Planetary Expedition. Anyone who enjoys travelling by SRV would find almost any part of the route challenging and entertaining: http://buckyballracing.org.uk/kumay.html
One member of the group found it so interesting he went round again following the equator.
Lots of superb screenshots (a selection starts about here: https://forums.frontier.co.uk/threads/t ... 05/page-11
) with even more on the Discord channel.
Many difficult mountains of ice or rock to climb, beautiful canyons to run and jump - well worth the time and effort.
