Teufelsee und Pfaffensee zwischen Echzell und Reichelsheim-Weckesheim, Nature reserve with twin lakes near Echzell, Germany.

Teufelsee and Pfaffensee form a nature reserve with two lakes surrounded by forest areas, together covering roughly 94 hectares. Three observation towers offer views of both lakes, and paved paths connect the access points from the nearby towns.

The two lakes are flooded remnants of open-cast lignite pits in the Wetterau coalfield, southwest of Echzell's centre and northeast of Weckesheim. The 93.7-hectare area was placed under protection in 1998 under the code 1440037, enclosing both water bodies. The L 3412 runs along its northwestern edge, with the K 179 to the west and the K 180 to the east.

The reserve's name pairs two former lignite pits: Teufelsee, "devil's lake", and Pfaffensee, "priest's lake". The lakes lie in the Wetterau brown coal district, and the protected area of about 93.7 hectares was established in 1998 under code 1440037. The L 3412 runs along its northwestern edge, with the K 179 to the west and the K 180 to the east.

Paved paths make it comfortable to walk to the three observation towers, which are reachable without long hikes. Access points from Reichelsheim, Echzell, and Weckesheim offer different starting points depending on where you begin.

Specialized amphibian waters line the shore zones and provide habitat for rare frog and newt species. Around 5 kilometers of hedgerow structures run through the area and serve as nesting and shelter places for songbirds.
