Overland travel planners — what they are, how they work, who they're for

An overland travel planner is a tool that maps a route between two places using surface transport only — trains, buses, ferries, shared taxis — instead of flights. It typically breaks a long journey into a chain of stops, each connected by a real transport option, and gives an estimated duration, cost, and way to book that leg.

bysloth is a working example of this: enter any two cities and it returns a realistic overland route between them, leg by leg. Independent resources like Seat61 have documented international rail and ferry connections this way manually for years; a planner does the same lookup automatically.

It takes an origin and a destination, works out a sequence of intermediate stops connected by real surface transport, and estimates time, cost, and booking options for each leg. Some tools do this from a hand-curated database of routes; others, like bysloth, use AI to generate a plausible route and then flag which legs it's confident about versus which ones need the traveler to double-check schedules before booking.

On bysloth specifically: you enter a starting city and an end city, pick a pace (fast, balanced, or slow), and it returns a stop-by-stop itinerary with a duration and cost estimate, plus booking links for each leg's operator.

Anyone traveling between two places without flying — for a lower carbon footprint, to see more of the route itself, or because flights aren't practical for that trip. In practice this is mostly:

Slow-travel and backpacker-style travelers stringing together buses and trains across multiple countries; climate-conscious travelers deliberately avoiding flights; and anyone who'd rather not manually research transport options city by city for a long multi-stop trip.

bysloth is a planner for overland travel. Give it two cities and it maps a realistic route between them using trains, buses, ferries, shared taxis, and the occasional hitch — and is upfront about which legs it isn't fully sure about, rather than presenting every estimate as equally certain. It's currently in private beta (v0.4).

No — bysloth plans the route and links out to the relevant booking site or operator for each leg. It doesn't process payments or issue tickets itself.

Trains, buses, ferries, shared taxis, and occasionally hitchhiking — no flights. bysloth is deliberately overland-only; if a leg would require flying, it isn't offered as an option.

Each leg is labeled with a confidence level, so you can see at a glance which parts of the route are solid and which need to be double-checked before booking. bysloth is upfront when it isn't sure about a specific schedule or connection, rather than presenting every estimate as equally reliable.

Yes — bysloth is free during its current private beta, with no paid plans. See pricing for details.
