Solarpunk travel is intended for /sustainable/ travel, right? So where can we discuss travel with no sustainability relevance? I only consider proper decentralized non-Cloudflare instances. This is what found as free world venues for travel chatter:

• !solarpunktravel@slrpnk.net ← sustainable travel focus
• !traveltips@feddit.uk ← Europe focus
• !travel@eviltoast.org
• https://lemmy.globe.pub ← whole instance devoted to travel (⚠but note there is an instance-wide no politics rule)

The places other than !solarpunktravel@slrpnk.net are ghost towns but that’s nothing that can’t be fixed with a bit of cross-posting. I suggest putting them in the sidebar as related communities.
