E9 section 4: Karosta - Ziemupe

The E9 Section 4: Karosta – Ziemupe is a 22-kilometre point-to-point coastal trail in Latvia’s Kurzeme region, gaining approximately 40 m of elevation across a single hiking day. Rated hard due to soft sand and exposed beach terrain, this stage of the International Walking Network’s Baltic Coastal Hiking Route runs from Liepāja’s historic military district past ruined fortifications and windswept foredunes to the remote estuary village of Ziemupe.

About the E9 section 4: Karosta - Ziemupe

The E9 Section 4 sits within the Baltic Coastal Hiking Route — a 1,800-kilometre long-distance footpath that traces the eastern shoreline of the Baltic Sea from Tallinn, Estonia, south to Gdańsk, Poland. In Latvia, the route carries the International Walking Network (IWN) designation E9, one of eleven European Long Distance Paths maintained by the European Ramblers’ Association. This 22-kilometre stage is one of the most physically demanding days on the Latvian coast, rated hard by the trail authority because it covers kilometre after kilometre of open beach with no firm underfoot surface and virtually no shelter from the wind.

The stage begins in Karosta — literally “War Port” in Latvian — the former Soviet-era military district that occupies the northern section of Liepāja, Latvia’s third-largest city. Sealed to civilians until 1994, Karosta has spent the past three decades transforming from a restricted naval base into a hauntingly atmospheric heritage site. Crumbling brick fortifications, decommissioned coastal artillery batteries, and partially inhabited Soviet apartment blocks give this neighbourhood a character unlike anywhere else on the Baltic trail. Hikers who start early can spend a full hour exploring the ruins before the route even reaches the beach.

After crossing the Fortress Canal, the trail enters a short stretch of coastal meadow before descending to the beach itself. From here, the path does not leave the shore for the remaining 18-plus kilometres. There are no shops, cafés, or water sources between Karosta and Ziemupe — a fact the trail authority explicitly states. Carry a minimum of 2 litres of water and enough food for a full six to eight hours of walking. Many hikers stay in Liepāja the night before; the city has a good range of accommodation, restaurants, and a main bus terminal with connections to Rīga.

The terrain alternates between firm sand close to the waterline at low tide and energy-sapping deep sand higher on the beach. A line of foredunes — some rising to 8–10 metres — runs along the inland edge of the beach. Storm erosion has carved exposed bluffs from several of these dunes, creating short scrambles that slow the pace on the northern half of the route. Birdlife is exceptional: the Kurzeme coast is a significant migration corridor, and species including white stork, marsh harrier, and common sandpiper are regularly seen along the estuary margins. Before packing your food bag for this long beach day, the guide on how many calories you need hiking a full day is worth reading.

Route Overview & Stages

The 22 km divide naturally into three segments defined by the river crossings. The Lenkupe and Kārļupīte are shallow rivers typically fordable in summer, but they run ankle-to-shin deep in spring and after heavy rain — waterproof footwear or sandals for the crossings are recommended.

Highlights & Points of Interest

• Karosta Military District — The former Soviet naval base covers 9 square kilometres and contains an extraordinary collection of 19th- and 20th-century military architecture. The red-brick Northern Fort, the Orthodox naval cathedral of St Nicholas, and derelict Soviet barracks are all accessible on foot before the trail begins.
• Fortress Canal — Constructed in the late 19th century to connect the naval harbour to the open sea, this canal crossing marks the formal start of the beach section and is the dramatic departure point where the trail transitions from industrial heritage to wild coastal nature.
• Northern Battery (Ziemeļu baterija) — A sprawling 19th-century coastal gun emplacement set directly above the beach. The concrete gun platforms and magazine tunnels are partially accessible and offer elevated views back toward Liepāja’s silhouette.
• Lenkupe River Estuary — A wildlife-rich wetland where the Lenkupe meets the sea. Reed beds support breeding marsh harrier and bittern; the ford crossing brings hikers to water level for close-range encounters with wading birds at the river mouth.
• Kurzeme Foredune Ridge — The foredune system here reaches 8–10 metres in places and represents one of the most intact dune landscapes on the southern Latvian coast. Winter storms have sheared several faces, exposing bare sand bluffs and the root systems of ancient coastal pines.
• Kārļupīte River — A shallow tidal river roughly mid-route that signals the beginning of the trail’s most remote stretch. No inland tracks or roads reach this coastline — the beach is the only route south from here to Ziemupe.
• Ziemupe River & Shipwreck Site — Local records note that multiple ships sank in the mouth of the Ziemupe River, including at least one vessel believed to have carried bronze cannons. The estuary is now used by small traditional fishing boats.
• Ziemupe Village — A compact fishing settlement of around 100 permanent residents. The village marks the end of Section 4 and has a guest house that serves as the nearest resupply point along the entire 22 km stretch south of Karosta.

Best Time to Hike the E9 section 4: Karosta - Ziemupe

The Kurzeme coast is hikeable from May through September. Conditions as of 2026, based on historical weather records and Baltic Trails authority seasonal reports, are summarised below.

Best single month: June. Temperatures sit in the comfortable 15–20 °C range, daylight extends past 10 p.m. giving ample flexibility if the sand slows your pace, and the beach is significantly quieter than July. The Karosta heritage sites run extended opening hours from June onward, and the Lenkupe wetlands are at their most active for bird migration in late May and early June.

Avoid October through April. The Kurzeme coast receives strong westerly gales in autumn and winter that make open-beach walking genuinely hazardous. River crossings can swell to waist depth and the exposed foredune sections are vulnerable to storm surge that can temporarily cover sections of beach entirely.

Practical Information

Accommodation

There is no accommodation between Karosta and Ziemupe. The 22 km beach section is completely undeveloped. The practical approach is to sleep in Liepāja the night before departure and at the Ziemupe guesthouse on arrival before continuing south.

• Liepāja (start city) — Hotels from €40 per night; hostels from €12. Both the Old Town and the Karosta neighbourhood have options within walking distance of the Fortress Canal start point.
• Ziemupe Guesthouse — The only accommodation at the end point. Expect basic rooms at approximately €25–35 per night with very limited capacity — book well in advance. Contact details are available via the Latvia Tourism Board long-distance hiking trails page.
• Wild camping — Legally permitted on the beach above the high-tide line in Latvia, provided no fires are lit in protected dune zones. Camp on the open sand rather than in or directly behind the foredunes, which are ecologically protected habitat.

Getting There & Back

Liepāja is the gateway city for this section. From Rīga, the journey takes approximately 3 hours by direct coach (Lux Express and Ecolines both serve the route; tickets from €8–15 one-way). There is no direct rail connection from Rīga to Liepāja. Liepāja Airport (LPX) handles seasonal domestic flights from Rīga and limited international services.

Returning from Ziemupe requires planning ahead. A local taxi from Ziemupe to Liepāja covers roughly 30 km and costs approximately €20–30; pre-arrange this through your guesthouse as there are no taxi ranks in the village. Alternatively, continue hiking south on Section 5 toward Pāvilosta (a further ~20 km), which has better bus connections back to Liepāja.

Permits & Fees

No hiking permit or trail fee is required. The beach and foredune area is open public-access land throughout Latvia. Karosta itself is freely accessible on foot. Some individual heritage buildings within the former military district offer guided interior tours for €3–5; the Northern Battery exterior, the general Karosta streetscape, and all beach walking are entirely free to access.

Gear & Packing List

Beach hiking places specific demands on equipment. Soft sand punishes heavy loads and rigid soles, while the open Kurzeme coastline offers no shade or wind shelter across most of the 22 km.

• Pack — A lightweight trail vest or day pack is the right tool for this single-day stage. The Salomon ADV Skin 20 carries 2+ litres of water, a full day’s food, and emergency layers without overloading on soft sand. Hikers tackling multiple Baltic stages back-to-back will appreciate the Fjällräven Abisko Hike 35, which provides 35 litres of structured capacity with frame-sheet load transfer that works well across mixed beach and forest terrain. For a minimal approach on fast days, the Salomon ADV Skin 12 fits a hydration bladder and essentials at just 160 g.
• Footwear — Trail runners with a low heel-to-toe drop shed sand faster than hiking boots and flex naturally with the uneven surface. Bring a separate pair of sandals or lightweight shoes specifically for the river crossings at Lenkupe and Kārļupīte — crossing in wet trail runners for 15 remaining kilometres is uncomfortable.
• Water — Carry at least 2 litres from Karosta. There are no safe freshwater sources on the beach between start and finish. A hydration bladder inside the pack keeps water accessible without stopping.
• Wind shell — A packable wind jacket is non-negotiable. Baltic coastal winds can gust to 60 km/h even in summer, and once you are sweaty from the sand slog even a mild breeze drops the feel temperature sharply.
• Sun protection — The open beach offers zero shade for roughly 16 of the 22 km. SPF 50+ sunscreen, a wide-brim hat, and UV-blocking sunglasses are essential from May through August on this exposed coastline.
• Navigation — Download the GPX track from the Baltic Trails website before departure. Mobile signal is patchy south of the Lenkupe River. A GPS device loaded with the route provides a reliable backup when the beach offers no landmarks.

Frequently Asked Questions

When is the best time to hike E9 Section 4: Karosta to Ziemupe?

June is the single best month. Temperatures reach a comfortable 15–20 °C, daylight extends past 10 p.m. giving flexibility if the sand slows your pace, and the beach is considerably quieter than peak July. May is an excellent alternative if you prefer cooler conditions and maximum solitude. Avoid October through April — coastal gales and storm-surge risk make the open beach genuinely hazardous.

How difficult is E9 Section 4?

The trail is rated hard by the Baltic Trails authority. The challenge comes almost entirely from terrain rather than elevation: walking 22 km on soft beach sand demands roughly 30–40% more energy than the same distance on a firm path. There are no technical climbing sections, but two shallow river crossings add variety. Strong cardiovascular fitness and resilient ankles will make a significant difference on this exposed coastal stage.

How many kilometres should I plan per day on this trail?

Section 4 is designed as a single-day walk covering 22 km from Karosta to Ziemupe. Budget six to eight hours of moving time depending on your pace on sand and time spent exploring Karosta at the start. Begin by 8 a.m. from the Fortress Canal to leave comfortable daylight margin. Combining Sections 4 and 5 in one day is possible for experienced beach hikers but pushes the total above 40 km and requires exceptional fitness.

What accommodation is available along E9 Section 4?

There is no accommodation anywhere on the beach between Karosta and Ziemupe — the entire 22 km is completely undeveloped. Plan to stay in Liepāja (hotels from €40, hostels from €12) the night before departure, then overnight at the Ziemupe village guesthouse (approximately €25–35 per night, limited rooms, book well ahead) on arrival. Wild camping on the open beach above the high-tide line is legally permitted in Latvia.

Do I need a permit or pay a fee to hike E9 Section 4 in Latvia?

No permit or fee is required to walk this section. The entire Baltic coastal beach route in Latvia follows open public-access land with no trail charge or registration needed. Some heritage buildings inside the Karosta military district offer paid interior tours at €3–5, but the exterior of the fortifications, the Northern Battery gun platforms, and all beach walking are completely free to access year-round.
