10:00

Sidirokastro Castle

Drive to the castle from the center of Sidirokastro and set aside about an hour for the climb and the visit to the ruins. From the hilltop, there is a lovely view over the town and the Strymonas valley; wear shoes with suitable soles, as the ground can be uneven. External visits are generally free, but accessibility may depend on site conditions.

Bring water and check the route conditions locally before heading up.

11:30

Agistro Thermal Baths

Continue by car toward Agistro, allowing roughly 25–30 minutes, and enjoy a stop of about an hour at the thermal baths. The area is known for its warm waters and traditional spa facilities; admission can vary depending on the pool or service chosen, roughly €5–€15. Allow time to change and for a short walk around the village.

Bring a swimsuit, towel, and sandals; check the facility hours in advance.

13:00

Lunch in Agistro

Stop at a village taverna for a leisurely lunch before setting off again. Look for local grilled dishes, salads, and seasonal specialties; a simple meal costs roughly €12–€25 per person, drinks excluded or included depending on the place. Booking ahead is useful on weekends and during busy periods.

Ask for the bill and the daily specials before ordering.

14:15

Roupel Fort

Reach Fort Roupel in about 15–20 minutes and allow at least an hour for the visit. The complex tells the story of the defense of Roupel Pass during World War II: follow staff instructions and respect any restricted areas. Entry is often free or low-cost, but opening hours and access arrangements can change because this is a military site.

Bring an ID document and check before departure whether the visit is allowed that day.

16:00

Excursion on Lake Kerkini

Continue by car to the lake, allowing about 45–60 minutes depending on the boarding point and traffic. If you have booked a boat with a local operator, set aside about 90 minutes for the excursion: the scenery changes with the water level and the season, and you may spot numerous bird species and, sometimes, buffalo. Shared tours cost roughly €10–€20 per person; price and availability should be agreed directly with the operator.

Book in advance and bring binoculars; sightings are not guaranteed.

18:00

Kerkini Dam

Reach the dam by car for a scenic stop of about 30–40 minutes, ideal for taking in the reservoir and the late-afternoon light. Stop only in permitted areas and do not enter technical or service zones. The walk is free; keep in mind that the water level and the appearance of the banks vary throughout the year.

Check sunset time and leave enough time for the return trip.

19:00

Dinner and return to Sidirokastro

Head back to Sidirokastro, allowing about 30–40 minutes of driving, and end the day with dinner at a local taverna. Expect to pay roughly €15–€30 per person for a full meal, depending on the dishes and drinks. If you are not very familiar with the road, avoid staying by the lake after dark and drive carefully on the side roads.

The return trip may take longer if the boarding point is far away or there are roadworks.
