Just as there were once several silk roads, so there were several hippie trails. Taking off from an earlier comment on Morocco, I’ll point out that there were a few that went further south into West Africa. By the time I travelled one of them, in the late 1970s, the hard-core hippie culture was fading, but several of the main elements were still in place — there were still enough young backpackers, mostly European, to fill the hostels and the cheaper hotels in places like Bamako and Mopti, where one might not have expected to find any tourists at all.
Though I could not fully appreciate it at the time (for I had no idea what was coming), one of the great things about that travel — and this comes to mind every time I read someone forums like this moan about bad wi-fi in their lodgings — is that in those final years of the wonderful pre-communications era, when there was no e-mail, instagram, or tik-tok, once you went “in there,” you were really in there; and you didn’t go in there unless you were content to be out of touch with your “loved ones” until you eventually emerged. Though this didn’t deter the back-packers, it otherwise had a salutary effect on the risks of the mass horde-tourism that we endure in so many places today.
(I might add that there were no universal ATMs either -- you went on such a trip carrying the cash which you had estimated you would need, knowing full well that Upper Volta or the Ivory Coast, fascinating as each was to visit, might be an inconvenient place to discover that you had underestimated!)
