Things to Do at Kuzalan Waterfall and Mavigöl: Giresun's Green Paradises

In one of the Eastern Black Sea's valleys draped in countless shades of green, in the village of Kuzalan in Giresun's Tirebolu district and far from the city noise, two natural wonders await you. The first is Kuzalan Waterfall, which flows like a silver ribbon through lush forests. The second is Mavigöl, fed by the falls and famous for its emerald-green waters. Stretching along the Aksu Valley, this route is one of the most special corners of the Black Sea for anyone looking for hiking, photography or a peaceful nature escape. It may not be as well known as Uzungöl or Ayder, but it is exactly the place for travelers seeking a quieter, unspoiled atmosphere away from the crowds. In this article, we cover everything you need to see and experience in the region, from Kuzalan Waterfall to Mavigöl and from Tirebolu Castle to the local dining tables.

Things to Do at Kuzalan Waterfall and Mavigöl

Two stops lie at the heart of this route. The first is Kuzalan Waterfall, where the Aksu Stream tumbles down the rocks. Dropping from a height of around 15-20 meters, the waterfall keeps its cool, abundant flow even in the summer months. Wooden viewing platforms and small cafés set right in front of the falls let you relax while feeling the cool spray. If you like, you can also take a break by dipping your feet in the natural pools just below the waterfall. The second stop is Mavigöl (Aksu Lake), a few kilometers from the falls, which takes its name from the distinctive turquoise-green color of its water. The secret behind this color lies in the minerals carried by the water that feeds the lake and in the reflection of the dense surrounding vegetation. The lakeshore offers a short walking trail, seating areas and scenic terraces. A full loop around the lake takes 20-30 minutes, depending on your pace.

As you make your way through the valley, footpaths winding between small tea and hazelnut gardens offer a close-up look at rural life in the region. The wooden and stone village houses you will often spot along the roadside are fine examples of Black Sea rural architecture. If you have the time and energy, we recommend covering the trail between the waterfall and the lake on foot rather than by car. That way you can experience the sounds of the valley, the birdsong and the babbling stream much more closely.

A little further down the valley, where it meets the coastline, you reach the town center of Tirebolu and its historic castle. If time allows, ending the Kuzalan-Mavigöl route with a short seaside stop in Tirebolu lets you see both the highland and coastal sides of the Black Sea in a single day.

Best Time to Visit

The ideal time to visit Kuzalan Waterfall and Mavigöl is from late May to September. During these months the weather is generally mild, the vegetation is at its most vibrant and the waterfall's flow is still strong. July and August are especially popular with visitors who want to enjoy the Black Sea's humid yet cool highland climate. Escaping the coastal heat for the cool of the valley is one of the region's classic summer rituals. In June, snowmelt brings the waterfall's flow to its peak, making the scenery even more spectacular.

In autumn, especially from late September to mid-October, the region takes on a beauty all its own as the leaves begin to turn gold. The weather is still pleasant for exploring and the summer crowds have largely thinned out, creating a quiet, tranquil setting for photography enthusiasts. In winter, snow and heavy rainfall at higher elevations can make road conditions difficult, and on some days access may be cut off entirely. If you are planning to visit during this season, be sure to check the weather forecast and road conditions in advance. Early morning is recommended for the best light and the fewest crowds, and weekday visits are much calmer than weekends.

Local Cuisine: What to Eat and Where

Black Sea cuisine is known for its simple yet hearty flavors, and the Giresun-Tirebolu area is full of fine examples of this tradition. The village breakfast spots and small family-run restaurants you'll find along the valley and in Tirebolu serve local specialties in their most authentic form. The must-try dishes include:

• Mıhlama (Muhlama): An iconic Black Sea dish made with clarified butter, cornmeal and fresh village cheese, served piping hot.
• Kuymak: A creamy cheese dish similar to mıhlama, known by a different name in some areas and eaten with bread or cornbread.
• Anchovy pilaf and fried anchovies: The Black Sea's signature from the sea, available in season at the restaurants along the Tirebolu coastline.
• Black cabbage soup: A hearty soup made with the Black Sea's own black cabbage, cornmeal and sometimes diced meat, especially loved in winter.
• Laz böreği: A famous dessert made with a pudding-like cream between thin layers of pastry and drizzled with the region's signature clarified butter.
• Giresun hazelnuts: The region's world-famous product. Don't head home without picking up some freshly roasted hazelnuts from the roadside village markets.

The small tea gardens around the waterfall and the lake offer a simple but delicious break with local gözleme and cornbread. In the restaurants of central Tirebolu, you'll find a wider Black Sea menu. The fish restaurants along the coast serve fresh Black Sea fish such as anchovy, whiting and horse mackerel at reasonable prices, depending on the season. For a lunch break with a sea view, the Tirebolu waterfront is a great choice. On your way back to the valley, the small stalls set up by villagers make for a nice shopping stop to round off your trip, with fresh honey, candied chestnuts and homemade jams.

Photo Spots and the Best Shots

The wooden platform directly opposite Kuzalan Waterfall is the most striking spot for capturing the water as it pours over the rocks. In photos taken before noon, before the sun is directly overhead in the valley, the texture of the water comes out much sharper. At Mavigöl, wide shots taken from the far shore best capture the water's distinctive turquoise hue. On misty mornings, the haze that forms over the lake's surface creates an almost cinematic atmosphere, making it the perfect time for "Instagram-worthy" shots.

The green tea gardens and wooden village houses along the valley also make a lovely backdrop for wide-angle shots. The rocky ground just below the waterfall is ideal for photography enthusiasts who want to try long exposures. For these shots, where the water takes on a silky texture, we recommend bringing a tripod. Once you reach Tirebolu, sunset photos that frame the castle and the sea together may well become the most memorable shots of your trip. For drone users, the valley looks like a green carpet in aerial wide shots. However, before flying a drone in the area, it's important to check the current regulations and any local restrictions.

Tirebolu Castle and the Region's Historical Significance

Tirebolu, known in antiquity as Tripolis, is one of the oldest settlements on the Black Sea coast. Rising on a small islet in the town center, Tirebolu Castle dates back to the Byzantine era and was later repaired and fortified by the Genoese. For this reason, locals sometimes call it the "Genoese Castle." Set at a strategic point on the Black Sea trade routes, the castle served both defensive and lookout purposes throughout history. During the Genoese period, the region was an important stop on the Black Sea trade network, considered an extension of the Silk Road.

Kuzalan and the Aksu Valley, meanwhile, have been the center of the local highland pasture tradition and of tea and hazelnut farming for centuries. The stone village houses and terraced gardens you still see in the valley today bear the marks of this heritage. The tradition of seasonal highland migration, handed down from generation to generation, involves moving livestock and families up to the high pastures in summer. Although it is now intertwined with tourism, it has largely preserved its cultural identity. When visiting the region, we encourage you to look beyond the natural beauty and take in this layered history and these living traditions as well.

Practical Tips

• Footwear: The trails around the waterfall and along the lakeshore can be damp and slippery, so comfortable walking shoes with non-slip soles are a must.
• Clothing: The weather in the Black Sea mountains can change suddenly, so we recommend bringing a light raincoat or windbreaker, even in summer.
• Carry cash: Some of the small cafés and gözleme spots in the valley may not accept cards.
• Go early: The area can get busy in the afternoons, especially on weekends, so choose the morning hours for a peaceful visit.
• Mosquito repellent: Insects can be plentiful by the stream and lake in summer, so having repellent with you will make things easier.
• Leave no trash: The area is home to local residents and a delicate natural ecosystem, so treating nature with respect is important.
• Water and snacks: Shopping options in the valley are limited, so we recommend bringing enough water and light snacks, especially if you're planning a long hike.
• Mobile coverage: The signal can weaken at times in the inner parts of the valley, so it's safer to make important calls while you're in central Tirebolu.
• Families with young children: Some spots along the lakeshore have no railings, so it's best to keep a close eye on children.
