The Basilica of Notre-Dame de la Garde, a must-visit in Marseille, offers stunning panoramic views of the city and the Mediterranean Sea from its hilltop location. Easily accessible by the local bus or a scenic uphill walk, it's worth the effort for its remarkable architecture and peaceful ambiance. Visitors can explore solo, although guided tours can enhance the experience with historical insights. Although the basilica is open year-round, it's best visited in the milder months of spring and autumn to avoid the summer crowds and heat. Entry is free, but allow a couple of hours for a leisurely visit, especially if you plan to explore the surrounding park and enjoy the vistas. Don't forget your camera and a bottle of water when making the ascent!
