The Höwenegg crater is not one of the dolines typical of the Swabian Alb, but a real volcanic crater. Geologically, it belongs to the Hegau volcanic region. Basalt mining has also shaped the crater's current appearance. You have a wonderful overview from this point.

A very good viewpoint overlooking the crater lake, with a small rest area and information panel. Even though there is a large fence around the crater rim for safety reasons, a good view is still possible.

The region around Tengen, particularly in Baden-Württemberg and near the Black Forest, offers a diverse range of aquatic landscapes. You can explore unique geological formations like the Höwenegg Crater Lake, which is a crater lake formed in a former basalt quarry. There are also significant natural springs like Aachtopf (Aach Spring), Germany's most productive spring, and artificially created ponds such as Enge Pond, which was Switzerland's first pumped storage plant. Further afield, you'll find clear mountain lakes, reservoirs, and even quarry lakes.
Yes, several lakes in the broader region are great for families. Enge Pond is particularly family-friendly, offering a covered seating area, barbecue facilities, and a children's playground. The Jettkofen Quarry Lake, near Mengen, also provides a large lawn for sunbathing and fine sand for children to play in. Lake Titisee and Ehmetsklinge Reservoir are also known for their family amenities like swimming areas and pedal boats.
Many lakes offer excellent walking opportunities. A circular path leads around the Höwenegg Crater Lake, providing views of the 'Blue Eye' of the Hegau. For more extensive hiking, the Black Forest region, home to lakes like Titisee and Windgfällweiher, has numerous trails. You can also find various running and hiking routes around Tengen, such as those listed in the Running Trails around Tengen and Waterfall hikes around Tengen guides.
Absolutely. Lake Titisee is famous for its clear water and designated swimming areas. Lake Windgfällweiher is considered Southwest Germany's highest swimming lake, offering a beach and a 'back-to-nature' experience. Lake Degersee is praised for its early warming temperatures, making it suitable for swimming even when larger lakes are still cold. The Ehmetsklinge Reservoir and Wagenhauser Weiher also feature clean water and lidos for swimming.
Besides hiking and swimming, the lakes and surrounding areas offer a variety of activities. Lake Windgfällweiher is popular for windsurfing and paddleboarding. The Ehmetsklinge Reservoir has pedal boats available. Cycling is also a great way to explore, with routes like those found in the Road Cycling Routes around Tengen guide, which can take you past scenic water bodies like the Jettkofen Quarry Lake.
Yes, the region is home to the Aachtopf (Aach Spring), which is Germany's most productive spring. This natural monument is a fascinating sight, where water from the Danube seepage basin emerges, feeding the Radolfzell Aach. The geological formations around the Höwenegg Crater Lake, a former basalt quarry, also offer insights into the area's volcanic past.
The best time to visit largely depends on your preferred activities. For swimming and water sports, the warmer months from late spring to early autumn (May to September) are ideal. Lakes like Degersee warm up earlier in the season. For hiking and enjoying the natural beauty, spring and autumn offer pleasant temperatures and vibrant scenery, with autumn providing beautiful foliage around the lakes.
Yes, the region offers good opportunities for birdwatching. The Klingnau Reservoir, located near Hohentengen am Hochrhein, is an artificially dammed lake that has become a significant nature reserve and habitat for many bird species. The marshy areas on the opposite shore of Lake Degersee are also popular with birdwatchers.
While some lakes are popular, you can find quieter spots. The Bench by the Pond is a small, less-known pond that offers a peaceful break. Lake Degersee is also noted for offering a shoreline for swimming away from crowds. Exploring the smaller, unnamed ponds and streams often found along hiking routes can also lead to serene discoveries.
Visitors appreciate the diverse natural beauty, from the unique geological formations of the crater lakes to the clear waters of the swimming lakes.

The region is notable for its volcanic past, evident in the Höwenegg Crater Lake, formed in a former basalt quarry. This area is part of the Hegau volcanism, with the lake sitting in one of six eruption sites. Fossil finds of prehistoric animals in the lake sediment attest to a subtropical climate millions of years ago, making it a significant site for geological and paleontological interest.
