The area features a rare 'karst spring' phenomenon where underground water naturally surfaces at a consistent temperature.
The water in the springs is so clear that the bottom, filled with aquatic plants and sunken logs, is visible from the boardwalk.
The site serves as a habitat for protected species, including the European pond turtle and various dragonfly populations.
Large sections of the path are built directly over water, creating the impression of walking on the surface of the marsh.
The Fényes Nature Trail is a 1,350-meter-long boardwalk system suspended over a karst spring wetland area in Tata, Hungary. The springs emerge at a constant temperature of approximately 20–22 degrees Celsius throughout the year. The trail winds through a protected alder forest and marshland environment. Visitors can observe distinct aquatic ecosystems via clear, shallow spring pools. The site was designated a protected nature reserve in 2010 to preserve the rare habitat of the karst springs. The boardwalk was constructed to minimize human impact on the fragile wetland vegetation.

Bring mosquito repellent, as the humid wetland environment attracts insects throughout the warmer months.
Wear closed-toe, comfortable walking shoes even though the path is a boardwalk, as sections can be slick after rain.
Use binoculars for birdwatching, as the marsh is a significant refuge for local water birds.
Do not attempt to touch the water or step off the boardwalk, as the mud and plant life in the spring beds are ecologically sensitive.
Closed during winter months due to safety concerns regarding ice on the boardwalk.
Stay on the designated boardwalk at all times to protect the fragile aquatic ecosystem. Smoking and pets are strictly prohibited.
