There are two large lakes within city limits: Raduń (area - 227.10 ha, length - 6,050 m, shoreline - over 19,000 m, maximum depth - 25.6 m, average depth - 10.4 m) and Zamkowe (area - 129.57 ha, length - 3,350 m, shoreline - over 10,950 m, maximum depth - 41 m, average depth - 12.9 m). Lake Raduń is spanned by a suspension bridge. Next to the bridge in a beechwood forest is an Olympic Training Facility, the 'Bukowina'. Immediately after World War II, Winand Osiński and olympic coach Jan Mulak founded the training center and began training with the Polish track and field teams who represented Poland during the 50s and 60s. Poland's olympic kayak team trains here to this day.
On this lake is also the City Centre for Sport and Recreation (MOSiR - Miejski Ośrodek Sportu i Rekreacji) which makes a wide range of sporting equipment available, including motor boats, kayaks, water bikes and the leisure boat Delfin. The centre also serves as a starting point for numerous walking and biking trails as well as kayak excursions. The so-called Pętla Wałecka, a kayaking route that traverses six lakes begins here and ends at Lake Bytyń Wielki.
Situated on the shores of the lakes are numerous beaches, swimming areas, camping spots and sporting equipment rentals.
Within a short distance of the city are several equally attractive lakes including Chmiel Duży, Chmiel Mały, Raduń Mały, Ostrowiec Wielki, Łubianka, Łabędzie.
Numerous ruins of German fortifications and bunkers from World War II are found in woods surrounding Wałcz, especially in proximity to the lakes. Most of them however are inaccessible - blown up or filled with soil, to prevent accidents with careless tourists.
The lack of heavy industry in Wałcz and the surrounding areas has helped the city to maintain relative ecological cleanliness and is an excellent location for rest and relaxation.
