• Good opportunities for birdwatching and spotting mammals (deer, foxes, small carnivores) in quiet hours

• Hiking and nature walks (short circuits and longer forest trails)
• Photography — landscapes, macro (fungi, leaves), wildlife and especially autumn colors
• Picnicking and lakeside relaxation
• Camping and staying in park-managed bungalows or nearby guesthouses
• Birdwatching and seasonal nature observation
• Guided nature walks or local eco-tours (available from Bolu/nearby towns)

Best time to visit: Autumn (October–November) for peak foliage. Spring and early summer (May–June) are excellent for green landscapes, wildflowers and milder weather. Winters are snowy and access can be limited.

Mountain-forest climate with cool summers (comfortable daytime temperatures), chilly nights and cold, snowy winters. Rain is possible in transitional seasons; pack layers.

The park has a nominal entrance fee and additional charges for camping, bungalows or vehicle parking; fees and opening arrangements change seasonally—pay at the park entrance office. The park is effectively open year-round, but some facilities (bungalows, services, access roads) may close or be restricted in winter.

Located in Bolu Province; the nearest major town is Bolu (approx. 40–60 minutes by car depending on route and traffic). Access is by road; the last stretches are rural mountain roads that may be narrow and muddy in wet weather. Nearest major airports: Ankara Esenboğa and Istanbul (both require several hours by car). Public transport options are limited—best reached by car or organized tour from Bolu or nearby districts.

1–2 days to comfortably visit the main lakes, hike short trails and enjoy photography; overnight stays recommended to experience sunrise/sunset and quieter wildlife activity.

Sturdy waterproof hiking shoes, layered clothing (temperatures change quickly), rain jacket, hat and gloves in cooler months, binoculars, camera with extra batteries/SD cards, insect repellent and a small first-aid kit. In winter bring winter boots and traction where snow/ice are present.

Try regional specialties from Bolu area (local trout where offered, pastries and village-style meals). Souvenirs include local honey, handcrafts, wooden items and photographs/postcards. Respect local vendors and check for seasonal availability.
