What bike to bring?

My partner and I are planning on moving to Revy for a year in June. We are flying over from Scotland and will only be able one bike each with us.

We both have gravel bikepacking bikes - rigid with a max tyre width of 50mm. We really enjoy doing weekend (and longer when we have the chance!) bikepacking trips on good gravel/forestry tracks.

We also have a mountain bike each. My partner has a Specialized Rockhopper and I have a full-sus enduro bike. I enjoy more gnarly downhill riding but my partner prefers more flowy trails.

I'm a bit unsure of what bikes to bring. I don't know if gravel bikes will be meaty enough for the local bikepacking scene. I know what local routes like the Tour Divide call for bikes with chunkier tyres. On the other hand, I'm not sure that my partner's Rockhopper will be suitable for lift-assisted biking.

Can you buy a season pass for mountain biking in the summer? I can't find a price online.
