The Castle of the Moors (Castelo dos Mouros) is an 8th–9th century Moorish hilltop fortress whose granite walls snake along the ridges of the Serra de Sintra. Captured by King Afonso Henriques in 1147, it fell into ruin for centuries before King Ferdinand II restored it in the 19th century as a romantic ruin overlooking his Pena Palace. Walking its ramparts gives sweeping views over Sintra town, the Pena Palace and, on clear days, the Atlantic. It is a Portuguese National Monument and part of the UNESCO-listed Cultural Landscape of Sintra.

Good to know
SafetyThe rampart steps are old, worn and uneven, and become very slippery when wet. Sandals, flip-flops and smooth or heeled soles are unsafe; wear grippy trainers or hiking shoes.
SafetySome wall edges have low or no railings. When it is crowded you can be edged toward a drop while letting others pass, so keep a firm hold of children and older visitors.
SeasonRoughly 10:30–15:00 is the most crowded window. Arrive right at opening or after about 4 pm for thinner crowds and better light. There is little shade, so bring water, a hat and sunscreen in summer.
RulesEntry is not timed and tickets can be bought at the gate, but prices, opening hours and last-admission time (usually about 30 min before closing) change by season, so confirm the latest details on the official site before you go.
CautionAround Sintra's train station and bus stops, touts may claim the ticket machine is 'broken' or the site is 'sold out' to steer you to fake tickets or private shuttles. Buy only at the official ticket office or official website.
SafetyThe 434 tourist bus up to the castle and the station queue get very long and crowded on summer mornings. Watch for pickpockets in packed queues and buses, and wear your bag in front.
Practical info
Most visitors take the 434 loop tourist bus up from Sintra station (private cars are restricted), though walking trails also reach the castle. Wear sturdy footwear for the rampart walk, bring water and a windbreaker, and confirm current prices and opening hours on the official site before visiting.
