ST318 Sombor - Apatin

The ST318 Sombor – Apatin is an approximately 25-km point-to-point stage of the Sultans Trail in Vojvodina, Serbia, gaining barely 30 m of elevation across the flat Bačka plain in a single day. Rated expert because of its remote, lightly waymarked floodplain sections, it links the historic town of Sombor with the Danube fishing town of Apatin.

About the ST318 Sombor – Apatin

The ST318 Sombor – Apatin is one stage in the Sultans Trail, a 2,500-km cultural walking route that runs from Vienna to Istanbul across nine countries: Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Greece and Turkey. The full trail was developed by the Netherlands-based NGO Sultans Trail — A European Cultural Route and follows the historic 1529 westward march of Sultan Süleyman Kanuni, better known as Suleiman the Magnificent. Today the foundation describes it as "a path of peace and a meeting place for people of all faiths and cultures."

This particular stage sits deep in the Vojvodina region of northern Serbia, in the West Bačka District. It is a lowland walk: both Sombor and Apatin lie at roughly 85–90 m above sea level on the Danube floodplain, so the route is dead flat. The "expert" rating reflects navigation rather than physical climbing — long stretches cross open farmland, irrigation canals and riverside forest where waymarking is sparse and shade is limited. The reward is a quiet, untouristed corridor of the Danube, big skies over the Pannonian plain, and two towns rich in Habsburg and Ottoman-era history.

As a part of the broader International Walking Network (IWN), the ST318 connects to the adjacent Serbian stages, making it easy to build into a multi-day Danube itinerary. It directly follows the ST317 Bezdan – Sombor stage and continues south toward Bačka Palanka and Novi Sad. The Sultans Trail also incorporates portions of the E8 European long-distance path through this region, so experienced long-distance walkers will recognise the waymarking conventions.

Route Overview & Stages

The ST318 is a single day-stage, but it helps to see it in the context of its neighbouring Serbian Sultans Trail stages. Distances below are approximate, drawn from the trail's published Serbian section.

The ST318 itself breaks naturally into three parts. The first 8 km leave Sombor through farmland and orchards on quiet rural roads. The middle section drops onto the Danube floodplain, following dykes and forest tracks through the southern edge of the Gornje Podunavlje wetlands. The final 6–7 km bring you along the river embankment into Apatin, finishing at the town's riverside promenade.

Highlights & Points of Interest

• Sombor town centre — A green, tree-lined town of around 47,000 people, known for its leafy avenues, neoclassical County Hall and the 18th-century Carmelite church. It is one of the most attractive starting points on the Serbian section.
• Veliki bački kanal (Great Bačka Canal) — The historic 18th-century canal network that frames the approach to Sombor and links to the previous ST317 stage; one of Europe's oldest navigable canal systems.
• Gornje Podunavlje Special Nature Reserve — A 196 km² wetland and floodplain-forest reserve along the Danube, home to white-tailed eagles, black storks and red deer; the southern fringe brushes the trail.
• Danube embankment forests — Willow and poplar gallery forest along the river, flooded seasonally, alive with birdsong in spring and a welcome strip of shade in summer.
• Apatin fishing quay — The historic riverside heart of Apatin, long a Danube fishing and shipbuilding town, lined with cafés serving the local fish stew (riblja čorba).
• Apatin Spa (Apatinska banja) — A thermal spa on the edge of town with mineral-rich waters, a relaxing finish after a long flat day on the dykes.
• Apatin Brewery — One of Serbia's largest and oldest breweries, founded in 1756, brewing the well-known Jelen lager; the town's economic landmark.
• Danube River views — At Apatin the river forms the border with Croatia, and the wide channel with its sandy banks and river islands offers the trail's most expansive water views.

Best Time to Hike the ST318 Sombor – Apatin

The single best month to walk the ST318 is May. Spring on the Pannonian plain brings mild daytime temperatures of 18–24 °C, the floodplain forests are green and full of migrating birds, and the worst of the Danube's spring flooding has usually receded by mid-month, leaving the dyke paths dry and walkable.

April and early June are strong alternatives. April can be wetter and the lowest forest tracks may still be flooded, while June pushes temperatures toward 28 °C with the first mosquitoes arriving on the wetlands. July and August are the least pleasant period: Vojvodina regularly sees 33–36 °C, almost no shade on the open dyke sections, and dense mosquito clouds in the riverine forest near Apatin. September and early October offer a fine second window, with stable, dry weather around 20 °C and quieter trails.

Winter walking is possible but bleak — the plain is exposed to cold continental winds, fog is common from November to February, and as of 2026 the lowest riverside tracks can ice over or flood with little warning. Always check the current Danube water level before committing to the floodplain section, because high water can submerge several kilometres of the route.

Practical Information

Accommodation

Both ends of the stage have lodging, so most walkers sleep in Sombor and Apatin rather than wild camping. In Sombor, guesthouses and small hotels run roughly €30–55 for a double room, with a handful of private apartments on the lower end. Apatin has hotels near the spa and river from about €35–60, plus private rooms (privatni smeštaj) from €20–30 per person. Wild camping is not formally permitted inside the Gornje Podunavlje reserve, but the Sultans Trail Foundation notes that tents are useful on the trail's quieter stretches; ask landowners' permission and avoid the protected core zones. Budget €5–10 per night at the informal campsites near Apatin's riverbank.

Getting There & Back

Sombor has its own railway and bus station with direct services from Novi Sad (about 2 hours by train) and Subotica (around 1 hour). From Belgrade, allow 3–3.5 hours by bus or rail to Sombor. Apatin is connected to Sombor by regular regional buses that take roughly 35–45 minutes, making it simple to return to your start point or continue your journey. The nearest international airport is Belgrade Nikola Tesla (BEG), about 200 km and 3 hours south by road; Budapest Airport (BUD) in Hungary is a comparable 200 km to the north and is often the cheaper European gateway.

Permits & Fees

No permit or fee is required to walk the ST318. The trail crosses the southern edge of the Gornje Podunavlje Special Nature Reserve, where you should stay on marked tracks and respect seasonal restrictions in breeding areas, but there is no entry charge for through-walkers. If you plan to camp, fish or use a boat within the reserve, separate permits apply — check current rules with the reserve management before you go. Carry your passport, as the Apatin riverbank lies directly on the Serbia–Croatia border.

Gear & Packing List

Because the ST318 is flat but long, exposed and lightly shaded, the priorities are sun protection, water capacity and good footwear for muddy dyke tracks. A comfortable 35–55 litre pack is ample for a day stage or a light multi-day Danube section. For a fast-and-light approach, the 2400 Windrider keeps weight down on the long open kilometres, while the larger 3400 Windrider suits walkers carrying camping kit for the riverside sites. If you prefer a structured travel-friendly pack for the train-and-bus logistics, the Abisko Hike 35 is a solid daypack option.

Carry at least 2 litres of water — there are few reliable springs on the floodplain — plus high-SPF sunscreen, a sun hat, and insect repellent for the summer mosquito sections. Lightweight trail shoes work in dry conditions, but pack gaiters and waterproof socks if rain is forecast, as the dyke clay turns slippery fast.

Frequently Asked Questions

When is the best time to hike the ST318 Sombor – Apatin?
May is the best month. Spring temperatures of 18–24 °C, green floodplain forests and receded Danube flooding make for dry, comfortable walking. April and September are good alternatives, while July and August bring 33–36 °C heat, almost no shade on the dykes, and heavy mosquito activity in the riverside forests near Apatin.

How difficult is the ST318, and why is it rated expert?
The terrain is completely flat, with only about 30 m of elevation gain, so it is not physically demanding. The expert rating reflects navigation: long stretches cross open farmland and floodplain forest where waymarking is sparse, shade is minimal, and high Danube water can submerge sections. Carry a GPS track and check river levels before you set out.

How long does the ST318 take and how far is it per day?
The stage is roughly 25 km and is designed as a single day's walk. On the flat terrain most hikers complete it in 6–7 hours including breaks, averaging about 4 km/h. Start early in summer to avoid the midday heat, since there is little shade once you leave Sombor's tree-lined streets.

Where can I stay along the route?
Most walkers sleep in Sombor and Apatin rather than camping. Guesthouses and small hotels cost roughly €30–60 for a double, and private rooms run €20–30 per person. Informal riverside campsites near Apatin charge around €5–10. Wild camping is restricted inside the Gornje Podunavlje nature reserve, so plan town accommodation in advance.

Do I need a permit to walk the ST318?
No permit or fee is required to walk through. The route skirts the Gornje Podunavlje Special Nature Reserve, where you must stay on marked tracks, but there is no charge for through-walkers. Separate permits apply if you intend to camp, fish or use a boat in the reserve. Bring your passport, as Apatin sits on the Serbia–Croatia border.
