A while ago I took a flight trip from Bucharest to Bergamo, then Faro, then London, and back to Bucharest — paying about 100 euros total for the flights. What I liked most was that I actually stayed in every city along the way. No rushed layovers, no stressful short connections — every stop was a real destination.
Afterwards I tried to find more trips like that, but I couldn't find a site that showed this kind of multi-city loop. So I built one.
Penguin Hops finds round-trip flight loops where every city is a place you visit, not just pass through. The prices shown are the cheapest fares observed for each route that month — other dates may cost more.
