There is no shortage of water and water sports on and around the Loosdrechtse Plassen! The lakes are the heart of a protected area for flora and fauna, including many bird species. The pools were created by peat in the area and are separated from each other by dikes and islands. Historic country estates and scenic landscapes surround the waters and add to the authenticity of the area. You leave from the parking lot in Loenen aan de Vecht, where you can park your car for free. When you leave the built-up area, you cycle into a wetland area. In the middle of the polder is a hollow post mill from 1832: the Trouwe Waghter. This mill had to replace two other mills, which in other places fed the water board. Until 1948, the Trouwe Waghter drained the polder by means of a paddle wheel, but when it came into private ownership in 1950, the interior was broken out. In 1960 the property rights were transferred to Natuurmonumenten, who had the mill restored and made it turnable again. Then you come to Fort Tienhoven, which was built between 1848 and 1850 as part of the New Dutch Waterline. The fort existed, closed off the Tienhovense Vaart and guarded the inundation quay, a dam lock and the Kraaiennesters lock. The design is almost the same as that of Fort Kijkuit and Fort Spion. The fort is not accessible, but offers a nice view. You will then pass beautiful country estates, many of which were built by wealthy merchants in the Golden Age. Landhuis and Weerestein are two impressive inhabited country houses. They both date from the seventeenth century and many references can still be found in the architecture, but the gigantic residential houses Vechtzigt and Groene Vecht are equally impressive. The country estates of Queekhoven and Vegt and Hoff, located in Breukelen, are also beautiful to see. The current Vegt en Hoff was built in 1873, on the spot where previously stood a house that bore the name 'Grashuisse'. Not much is known about the origins of Queekhoven, because a raging fire completely destroyed the archives and the original house. Three other country estates that you will see from the bike during your trip are Oud Oever, Bijdorp and Vegtlust. Located along the east bank of the river Vecht, Oud Oever has a main building, a historic garden and park layout, a garden dome, gardener's house, horse stable, coach house and several entrance gates. Oud Oever was built around 1700 by Pieter van Beeck. He called the house Beek en Hoven at the time. This name was changed by his heir to Oud Oever 10 years later. Johannes Willem van Reenen bought four country estates in the nineteenth century that were next to each other on the Vegt. Bijdorp was one of them, another was Vegtlust, which was built in the eighteenth century. The other two were demolished and a beautiful park was created on the vacant piece of land. In 1981 Vegtlust was renovated and six apartments were built in it. But one of the best preserved smaller country estates in this area is Bijdorp, which was built around 1710. In total, this territory covers 1.2 hectares of land. Various parts of this country estate are protected because they are national monuments, such as the main building from 1700 and the historic garden and park layout.
