Trsteno Arboretum: a Renaissance garden above the Adriatic

Six centuries of plants, water and shade, north of Dubrovnik

Trsteno sits 18 km up the coast from Dubrovnik, a small village that would be unremarkable except for the extraordinary garden that the Gučetić noble family began planting in 1494. The Trsteno Arboretum is the oldest in Croatia and one of the oldest in this part of the Adriatic — a Renaissance garden that has grown, evolved and survived five centuries of war, fire and political upheaval.

For most visitors, Trsteno means one thing: the Game of Thrones garden. The arboretum stood in for the gardens of King’s Landing in seasons two through five, where characters including Cersei Lannister and Lady Olenna Tyrell held their scheming conversations beside antique fountains. The crew planted additional trees to fill out the look, but the underlying garden — its centuries-old plane trees, its nymphaeum fountain, its terraced layout above the sea — was already exactly what the production needed.

Croatia has used the euro since 2023, and Trsteno is a straightforward and economical stop: entry to the arboretum is €7–10 for adults.

Why visit Trsteno

Trsteno works on two levels. For history and botany enthusiasts, it’s a serious institution: a living record of plant collection and acclimatisation over 500 years, managed today by the Croatian Academy of Sciences and Arts, with specimens from across the Mediterranean, the Americas and Asia. For everyone else, it’s a beautifully shaded garden with exceptional Adriatic views — a genuine hour or two of peace in a region that can feel relentlessly busy in summer.

The Game of Thrones connection draws a certain category of visitor but doesn’t overwhelm the experience. This isn’t a theme park: the sets are long gone, and what remains is a real working arboretum. Those who want the full GoT treatment will want to pair it with the broader Dubrovnik Game of Thrones filming locations guide.

Trsteno also sits north of Dubrovnik on the road to Pelješac, making it a natural first stop on a drive up the coast. The South Dalmatia 10-day road trip includes it as a morning stop before continuing to Ston and the Pelješac wine country.

Top things to do at Trsteno Arboretum

Explore the Renaissance garden

The arboretum covers about 25 hectares arranged across terraced slopes above the sea. The central axis runs from the 15th-century villa down to the shoreline, passing through formal parterres (geometric flower beds framed by low hedging) that were the original core of the Renaissance garden. The nymphaeum — a grotto fountain with a figure of Neptune at its centre — is the most photographed feature and survives from the 16th century.

Two enormous Oriental plane trees near the entrance are among the oldest and largest in Croatia: their trunks require several people with outstretched arms to encircle, and their canopies shade a substantial portion of the upper garden. These trees were already ancient when Game of Thrones filmed here.

Allow 60–90 minutes to walk the main paths at a comfortable pace. Bring comfortable shoes; the terraced sections have uneven stone steps.

Spot the Game of Thrones filming locations

The arboretum served as the gardens of the Red Keep in King’s Landing — specifically as the setting for numerous political conversations, including Lady Olenna Tyrell’s appearances in seasons three and four, and various Lannister garden scenes. The nymphaeum fountain and the terrace above the sea are the most recognisable spots.

There are no permanent GoT signage systems in the arboretum (it is run as a scientific institution), so enthusiasts should consult the Dubrovnik Game of Thrones locations guide in advance to identify the specific spots. For those who want a structured GoT experience across multiple Dubrovnik-area locations, the original Game of Thrones tour including Lokrum covers the city sites; the complete Game of Thrones driving tour takes a vehicle between the wider filming locations and can include a Trsteno stop.

Walk down to the harbour and sea terrace

A path descends from the main garden to a small boat harbour below. The view from the sea terrace — the arboretum rising above you on the terraced hillside, the open Adriatic to the south — is one of the better composed landscapes in the region. It’s a particularly good vantage point in the late afternoon, when the light comes from behind the hills.

Visit the arboretum shop

The small shop at the entrance stocks plants propagated from the arboretum collection (good for gardeners), local honey and olive oil from nearby producers, and botanical books. It’s a worthwhile browse before or after the walk.

Where to eat near Trsteno

The arboretum has a small café near the entrance for coffee and cold drinks. For a proper meal, the village has Konoba Trsteno — a modest family restaurant a few minutes’ walk from the arboretum entrance with the standard Dalmatian menu of grilled fish and local wine at honest prices (mains €14–24). For a better choice, the restaurants in Dubrovnik are 25 minutes south, and combining Trsteno with a late lunch in the old town is a natural sequence.

How to get to Trsteno

By car: Drive north from Dubrovnik on the D8 coastal road for about 25 minutes. Parking is available in the village, a short walk from the arboretum entrance.

By bus: Local Libertas bus services from Dubrovnik Bus Station pass through Trsteno several times daily. Journey time is approximately 40 minutes. Ask the driver for the Trsteno arboretum stop. This is one of the few day-trip destinations around Dubrovnik that works on public transport.

By organised tour: Most Game of Thrones tours and some Pelješac day trips include a Trsteno stop. The driving GoT tour in particular suits this, since Trsteno is on the route north from Dubrovnik.

Is Trsteno worth visiting even if you don’t care about Game of Thrones?
