Located on the Mediterranean, Sant Feliu de Guíxols has idylic weather almost all year long. The coastline of Sant Feliu de Guíxols spreads over ten kilometres (6.2 miles). It also includes many little bays with coves surrounded by pines with rocky or fine sand beaches. The beaches are cleaned daily and a modern water treatment system prevents wastewater from entering the sea.

The town is engulfed by small mountains, with forests of pine, oak, and cork trees.

The name Sant Feliu goes back to the martyred saint, Feliu, who came from Africa. Guíxols is a word derived from the former word Iecsalis, of a document the 10th century that mentions to the monastery and that seems to mean "Rope-maker"

The Original Nucleus of the Town A township started to grow up on the basis of the various activities surrounding the Monestir de Sant Feliu de Guíxols. The settlement grew, and soon dwellings started to spring up on the other side of the watercourse, which would become the nucleus of the medieval town, centered on the market.

Monuments include:

• Sant Feliu de Guíxols Monastery.
• Plaça del Mercat. The market place serves as the heart of public and economic life in the town. A fruit and vegetable market takes place every morning on the 'Plaça'. On Sundays, the weekly market takes place along the Passeig and on the Plaça, a popular meeting place for residents.
• Passeig dels Guíxols. The boulevard of Sant Feliu de Guíxols is unique, and is a wide sandy walkway lined with trees; ideal for a relaxing stroll.
• Passeig del Mar. Opened in 1833, the seafront promenade was built between the medieval town and the sea. Little by little, the humble homes of fishermen from the medieval era were replaced by stately homes. Today, the area's architecture is mostly modern; because of real estate, many of the mansions are gone and condominiums have replaced them. Nonetheless, it makes for a lovely walk along the town's beach.
• Casino la Constància, constructed in 1888 by the architect General Guitart. It is also known as casino dels nois.
• Pedralta, which used to be the largest rocking stone in Europe.
• Old railway station, designed by architects Rafael Coderch and Gabriel March and built between 1889 and 1892, which served the line from Sant Feliu de Guíxols to Girona. It was used until 1969, and now serves as a public school. It is seen as a reminder of the town's progressive era.
• Historic residences. From the mid-to-late-19th century, Catalonia began to prosper economically and developed a bourgeoisie class. Sant Feliu de Guíxols has many examples of the elegant, bourgeoisie homes of this time period. Some examples are the casa Gaziel (1880), the casa Pecher (1894), the casa Maynegre (1898), the casa Girbau (1910), the casa Maruny (1909), the casa Ribot (1904), the casa de la Campana (1911), and the casa Patxot.
• The town hall, somewhat Gothic in style, yet simple, was originally built in 1547. It has survived battles and real estate. However, today it has a tower added on from 1847.
• Hermitage of Sant Elm. This small hermitage was founded in 1203. The chapel was built in 1452, and dedicated to Saint Elm; however, it was destroyed by the French in 1696. It was rebuilt in 1723, only to be damaged in 1943, during the Spanish Civil War; the present chapel was restored in 1993. It sits on a cliff above the sea.
• El corsari, a bar built in a cave
