Every summer, the city of Plovdiv pulses with energy as Hills of Rock Festival transforms the historic heart of Bulgaria into a vast stage. This isn’t just a music event—it’s an adventure in sound, culture, and camaraderie that challenges you to engage fiercely with the crowd, the city, and the music roaring through the night. Set against Plovdiv’s slopes, the festival invites rock fans and casual visitors alike to experience an electrifying blend of local grit and international headliners.

Founded in 2014, Hills of Rock has grown into Bulgaria’s premier rock festival, attracting tens of thousands under an open sky where the hills themselves seem to echo the power chords. Located near the park areas and Roman theatre, the terrain offers a unique blend of urban and natural environment—concrete steps, grassy knolls, and moderate inclines that invite crowds to stake out a spot or move with the wave of music.

This year’s festival spans three days, offering an intense lineup that stretches beyond classic rock into heavy metal, punk, and alternative sounds. Expect an immersive experience where the thrum of the bass reverberates through cobblestone streets and grassy patches. The festival’s layout encourages exploration—from main stages to lesser-known spots where local acts bring fresh energy. This spatial design makes the event feel like a festival hike: moving through different elevation points, feeling the pulse climb as the volume peaks.

Practical preparation is key. The festival grounds cover roughly a 2-kilometer radius with slight elevation changes (around 40-60 meters between top and bottom points). Paths vary from flat pedestrian streets to small hills with grassy embankments, providing convenient vantage points but calling for sturdy footwear. Prepare for heat during daytime with hydration and sun protection, as the Bulgarian sun can be relentless. Evening brings cooler, comfortable air but layers are advised for variable late-night temperatures.

Navigating Plovdiv before and after the festival rewards you with rich history—from the Roman Amphitheatre confronting modern crowds to cobbled lanes humming with cafes and street art. This balance of old and new extends to the festival itself: a rock gathering fiercely connected to place.

Whether you come to lose yourself in music, soak in the atmosphere, or both, Hills of Rock offers an adventure defined by sound, movement, and community. It demands engagement and respect, asking you to keep pace physically and emotionally with a festival that’s as much about the land and its people as it is the music.
