There is no shortage of water and water sports on and around the Loosdrechtse Plassen! The lakes are the heart of a conservation area for flora and fauna, including many bird species. The ponds were created by peat bogging of the area and are separated from each other by dikes and islands. Historic estates and scenic landscapes surround the waters, adding to the area's authenticity. You depart 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 seesaw mill from 1832: the Trouwe Waghter. This mill had to replace two other mills that drained the water board in other places. 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 operational again. Then you come to Fort Tienhoven, which was built in the period between 1848 and 1850 as part of the New Dutch Waterline. The fortress closed off the Tienhovense Vaart and guarded the inundation quay, a dam lock and the Kraaienster lock. The design is almost the same as that of Fort Kijkuit and Fort Spion. The fortress is not accessible, but it does offer a nice view. You 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 Queekhoven and Vegt en Hoff country estates located in Breukelen are also beautiful to see. The current Vegt en Hoff was built in 1873, on the spot where there previously stood a house that bore the name'Grashuisse\\\'. Not much is known about the origin of Queekhoven, because a blazing fire completely destroyed the archives and the original house. Three other country estates that you will see from the bike during your tour 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 to Oud Oever 10 years later by his heir. Johannes Willem van Reenen bought four country estates in the nineteenth century, which were located 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.
