After spending hours of pure relaxation in our thermal waters, some guests feel the call of an even more unspoiled natural world—one that tells stories of heroes and landscapes unchanged by time. If you’re looking for a different kind of day, far from the crowded beaches and the usual amenities, Cala Martina is the destination we recommend.
Located about 31 km from our hotel, this bay is a true gem of Mediterranean scrub and turquoise waters. We recommend that you approach this experience with the right mindset: that of an explorer who knows that, to discover the most beautiful treasures, you have to put in a little effort.
Beach Features
Cala Martina Beach
31 km from our hotelA journey through history and nature
Cala Martina isn’t just a beach; it’s a place steeped in history. According to tradition, it was here that Giuseppe Garibaldi set sail in 1849 to escape the Papal and Austrian troops, sheltered by the dense vegetation of the Maremma. Along the path leading to the beach, you’ll find a monument dedicated to the Hero of Two Worlds: the perfect spot to take a break, breathe in the fresh air and enjoy the view of the sea.
Unlike the sandy beaches of Marina di Grosseto, Cala Martina features a seabed of gravel and pebbles. This means two things: crystal-clear water that’s among the cleanest on the coast and a paradise for snorkeling enthusiasts.



Practical Guide: How to Organize Your Day
To get the most out of Cala Martina, planning is essential. Since it’s a protected natural area, you won’t find any beach clubs, bars, or amenities there. Here are our “local” tips to make sure you’re not caught off guard:
- The route: It’s about a 35- to 40-minute drive from our hotel to the Pian d’Alma area, the ideal starting point.
- The Hike: From the rest areas, you’ll need to continue on foot or by bike along a flat trail that winds through the Mediterranean scrub. The walk takes about 30–40 minutes. It’s one of the most beautiful stretches in the area, but remember: wear sneakers or hiking boots. Save your flip-flops for the beach; this trail requires sturdy footwear.
- Equipment: Since the cove is completely unspoiled, you’ll need to be self-sufficient. Bring plenty of water, snacks, sunscreen and, if possible, water shoes to help you move more easily over the pebbles. A diving mask is highly recommended: the seabed here is truly worth exploring.
A Return to Relaxation
We know full well that a day at Cala Martina takes a lot of energy: the walk, the sun, the sea. But there’s one priceless benefit: knowing that, when you return, the Terme Marine Leopoldo II is waiting for you.
There’s nothing better than returning from our “wild” cove to soak in the warm thermal waters, relax your muscles after a walk and end the day with a wellness treatment that will deeply rejuvenate you, leaving you ready for a new adventure in the Maremma.
Frequently Asked Questions (FAQ)
1. Is Cala Martina suitable for people with small children or strollers?
This isn’t the best option. Access is only via a 30- to 40-minute walk along a dirt path and the beach is made up of pebbles. For families with young children, we recommend the more accessible beaches in Marina di Grosseto, where the amenities and fine sand make for a more enjoyable day.
2. Are there any bars or places to eat on the beach?
Absolutely not. Cala Martina is a pristine beach with no amenities whatsoever. It is essential to arrive fully equipped with everything you need (water, food, sunscreen) and to follow the “leave no trace” rule by taking all your trash with you.
3. Do you need to be in particularly good physical shape to reach the beach?
The trail is flat and accessible; it doesn’t require any special athletic ability, but you should be used to walking a total of about 3–4 km (round trip). As mentioned, the most important thing is to wear appropriate footwear: avoid open-toed sandals or flip-flops when walking in the woods.
