Lago di Bracciano (the volcanic crater lake 40km northwest of Rome — 57 km², the second largest lake in Lazio after Bolsena, at 164m altitude in the volcanic complex of the Monti Sabatini, accessible from Rome via the Via Braccianese (SS493) or the Roma-Viterbo regional railway (FL3) from the Roma Ostiense or Roma Trastevere station to Bracciano station in approximately 55 minutes): Rome's most consistently used freshwater recreation destination, the lake that the Roman urban population has treated as its aquatic garden since the Roman period when the Aqua Traiana (109 AD) drew from the Bracciano lake as the water source for the Rome aqueduct supplying the right bank of the city.
The Lago di Bracciano circuit (the three distinct lakeside towns that give the lake its complete experience): Bracciano (the castle town — the Odescalchi castle visible from the lake, the most complete Orsini-Odescalchi medieval fortress in Lazio, the primary cultural monument of the lake circuit); Trevignano Romano (the beach town — the sandy volcanic shore, the best freshwater swimming near Rome, the sunset aperitivo on the lake promenade); and Anguillara Sabazia (the medieval borgo town — the peninsula historic centre with the medieval walls on the lake promontory, the most architecturally distinctive of the three Bracciano lakeside settlements). The three towns together constitute the complete Bracciano lake experience — the visitor who stays at a single town without completing the circuit misses the specific quality that each brings.
Lago di Bracciano: The Complete Circuit
Bracciano: The Castle
Bracciano (the town on the northeastern shore — the Odescalchi castle (formerly Castello Orsini-Odescalchi) on the hill above the town: the 15th-century castle built by Napoleone Orsini on the site of an earlier fortification, passed to the Odescalchi family in 1696 (the same year that their relative Benedetto Odescalchi became Pope Innocent XI), and maintained in continuous private Odescalchi family ownership to the present day — the castle interior accessible through the guided visit programme (odescalchi.it for times and pricing — approximately €12 adults), the most complete castle interior visit in the Rome province including the rooms decorated with the Orsini and Odescalchi family collections, the frescoed halls, and the armory).
Bracciano Lake Swimming
Lago di Bracciano water quality (EU "excellent" classification since the specific lake cleanup programme of the 1990s-2000s that addressed the agricultural and residential drainage issues that had reduced quality in the 1980s — the lake whose water Rome used for the Aqua Traiana aqueduct for 500 years is now once again at the quality that ancient Roman engineering intended). The best swimming access: the Trevignano Romano sandy beach (the finest Bracciano beach — see the Trevignano guide), the Anguillara Sabazia lido (the organized beach below the medieval borgo), and the Vigna di Valle beach (the free beach on the southern shore, accessible by the lake circuit road). Water temperature: 22-24°C in July-August, 19-21°C in June and September.
Q&A: Lago di Bracciano
What is the best way to do the Bracciano lake circuit?
By car (the most flexible — the 30km lake circuit road connecting all three towns): arrive at Anguillara Sabazia in the morning for the medieval centre walk (9:00-10:30), continue to Trevignano Romano for the beach morning (10:30-13:00), lunch in Trevignano, drive to Bracciano for the Odescalchi castle visit in the afternoon (15:00-17:00), return to Trevignano for the lakeside aperitivo (18:30). By public transport: the FL3 train from Rome to Bracciano (55 minutes from Roma Trastevere), then the COTRAL bus connecting the three towns on the lake circuit — the public transport circuit is feasible but requires more time management than the car circuit.
