Eighteen kilometres, which is the right distance
Poreč is the reason most people look at this part of Istria: the Euphrasian Basilica, the marina, the long run of coast either side of it, and more restaurants than a week can get through. It is also, in August, extremely busy.
Villa Bucks is 18 km inland, a 15 to 20 minute drive. That is close enough to go in for an evening and come back, and far enough that the group has a garden, a pool and silence at night.
What inland buys a group of this size
A seafront house for 20 people, if you can find one, is priced accordingly. Ten kilometres back from the water the same money buys 9 bedrooms, 7 bathrooms, a heated pool and 1,200 m² of garden.
It also buys parking. Twenty people arrive in four or five cars, and there are eight spaces at the house, five of them inside the gate — a detail that stops mattering only once you have tried to solve it in a coastal town in August.
The beach, when you want it
The nearest beach is a rock beach 10 km away, twelve to fifteen minutes by car. The Poreč coast, with the wider choice of swimming and the beach bars, is a few minutes further on.
Most groups settle into a rhythm of pool days and beach days. The pool is fifty square metres, private, and can be heated for €20 a day — which is why the pool tends to win.
And the rest of Istria from the same door
Being inland puts the hill towns within reach as well as the coast. Motovun is 22 km, Grožnjan 28 km, Hum — the smallest town in the world — 35 km. Rovinj is 40 km and Pula 55 km.
Aquapark Istralandia is 18 km, which is the single most useful fact on this page if you are travelling with children.
