Responsible Ways to Experience the Medes Islands
Scuba diving

Conservation in Practice: How Visitors Help
Conservation success depends on everyday choices. While local guidelines may vary by activity and conditions, these universal principles help protect marine reserves:
- Look, don’t touch: Avoid contact with coral, rocks, and marine life to prevent damage.
- Control buoyancy: Divers should maintain neutral buoyancy to keep fins off the seabed.
- Follow your guide: Guided activities help minimize impacts and improve safety.
- Pack in, pack out: Keep boats and beaches free of trash; plastics can easily reach the sea.
- Choose certified operators: Opt for experienced guides who prioritize environmental best practices.
The Reserve’s Coastal Context: A Park of Three Landscapes
The Medes Islands are only one facet of a rich mosaic. The Montgrí, Medes Islands and Baix Ter Natural Park spans sea, coast, and inland habitats:
- Montgrí massif: Trails lead to Montgrí Castle (built between 1294 and 1301 by order of King Jaume II), where a 360º panoramic view stretches from the Bay of Roses and Empúries to the Pyrenees and beyond.
- Secluded coves: The rocky Montgrí coastline shelters small coves preserved in exceptional condition—many reachable only on foot or by boat—for a tranquil, low‑impact beach day.
