Start Fazana. You will have the bike briefing in the evening and the rest of the time is free to relax and explore the village.
Today you can enjoy a gentle warm up ride to Pula. The ride is short so you can spend a good period of time here exploring the town. Pula has a long history and was brought to particular significance by the Emperor Augustus. Undoubtedly the most well-known site of the town is the amphitheatre, which was built during the reign of Emperor Vespasian. It was the 6th largest of its kind and is now use to stage film festivals and summer operas. The narrow streets of Pula offer a lovely place to enjoy a relaxing wander, with ancient monuments littered throughout the town, plenty of boutique shops, galleries, cafes and restaurants and of course the pretty harbour. You could spend all day here; alternatively, you could catch a boat to the Brijuni National Park - this was Tito's private island archipelago. With Roman villas, Byzantine villages, Tito's personal zoo and even his 1950s Cadillac make for an interesting visit.
Pedal inland through lemons, pines and olive groves to Istria's ancient capital of Vodnjan, a compact village full of Gothic, Baroque and Renaissance architecture. The St. Blaise cathedral is known for having the tallest tower in Istria (63m) and is host to an array of bizarre relics. You can pick up some lunch from the bakery, then head north for lunch amid stone beehive style huts - kazuna - near the 8th Century church of Sta Foska. You will then return along the coast passing the remains of Roman baths on the shore. Spend the evening back in Fazana where you can enjoy a sunset stroll along the harbour.
Head north through walnut, plum, almond and fig trees. A steady ascent brings you to Bale, known as Castrum Vallis by the Romans who built a castle here to protect their salt trade. It is then downhill to the sea and a sinuous coastal path under umbrella pine, bay-hopping for 8km by crystal seas. Rovinj is your charming destination, known as the Venice of Istria. The central basilica is surrounded by narrow marbled alleyways that by night are lit by the candles of the dining tables which spill out onto the streets. The bustling harbour offers a great atmosphere and you can also explore the museum, housed in a baroque mansion called Califfi Palace and displayed artwork, sculpture, jewelry collections and ceramics.
Today is free to explore Rovinj - lose yourself in the boutiques and art galleries or find a nice swimming cove. It is even possible to catch the ferry to Venice for the day. If you fancy getting back on the bikes, you can enjoy a lazy northern loop passing ruined churches, olive groves and oxblood coloured soils tilled by rusty tractors. Return to Rovinj to enjoy a swim and the evening atmosphere. After sunset some bars put cushions on the rocks so you can watch the underwater lights shimmer as the fishing boats return.
Take sun-dappled back roads inland to the head of the Lim Fjord - an impressive wooded valley and today's challenge. You will begin by freewheeling down to the base before ascending 2km to a fantastic panoramic viewpoint on the other side. You can enjoy lunch in one of the many grill restaurants en route, then head back to the sea to meet the coast 10km south of Porec. You can then follow the water to the pretty harbour and your waterfront hotel.
Porec is most famous for it's AD300 UNESCO heritage Basilica of Euphrasius with magnificent golden frescoes and intricate mosaics. The Basilica is right in the heart of Porec, just off the main street, it is very easy to find with the sparkling golden mosaic which sits above the entrance. You can visit it as you leave Porec today before heading north along the shore. The seaside tracks that you follow pass a Roman amphora factory and follow clear bays and headland for 10km. You will then inland to visit the giant Jama Baredine limestone cave before returning to Porec for your last evening. There are many waterfront restaurants, as well as some hidden treasures tucked away in the town.
