Samothraki · Therma & the forest · Θέρμα (Λουτρά)
Therma, also called Loutra, is a village of rooms, tavernas and gardens scattered under huge plane trees on the north coast, where warm, sulphurous springs rise at the foot of Mount Saos. Streams run through it on their way to the sea, the paths to the rock pools of Gria Vathra start at the top of the village, the Fonias gorge is a short drive east, and the trail to the summit of Fengari begins here. In summer it is the island's liveliest place, with a free-spirited crowd of walkers, families and long-haired campers who come back year after year.

Greetings from Therma
Therma
We spent the morning climbing from pool to pool at Gria Vathra, gasping at the cold every time we jumped in. Lunch was in the shade of a plane tree so big that four of us could not reach round it. In the afternoon we swam in the sea by the harbour, and tonight, after dinner, we went down to the hot springs in the dark and sat in the warm water under the trees, looking up at more stars than we have ever seen.
Hot springs, plane trees and running water at the foot of the mountain
Therma takes its name from the warm springs that rise here, close to the sea, rich in sulphur and other minerals. People have bathed in them since at least Byzantine times, and they still do: there is a municipal hydrotherapy building for proper baths, and simpler open-air pools where the warm water collects under the trees and anyone can sit in it, best of all late in the evening when the air is cool.
The village is not a village in the usual sense. There is no square and no old centre, just rooms, pensions, tavernas and gardens spread along the road and the streams under huge old plane trees. Water is everywhere: in channels by the road, in fountains, in the stream that runs past the taverna tables. On a hot August day it is several degrees cooler than the port.
Above Therma the forest closes in. A short path leads to Gria Vathra, a chain of waterfalls and green pools in the rock, and the river beyond comes down from the high slopes of Saos. A few kilometres east along the coast, the Fonias river falls through its gorge into the island's most famous pools. The marked trail to Fengari, the summit, starts on the edge of the village and climbs through oak and plane forest above the tree line to the bare rock at the top.
For decades Therma was also the heart of the island's free-camping summer. Tents spread under the plane trees east of the village, and young people from all over Greece and Europe came for weeks of rivers, music and bare feet. Free camping has been banned since 2025, and the campers now stay at the municipal site at Varades, but the easy-going spirit has stayed: yoga mats on the balconies, guitars at the beach bar, and nobody in a hurry.
Down by the sea there is a little harbour with fishing boats and a few yachts, a pebble beach with umbrellas and beach bars, and fish tavernas along the road. In the evening everyone drifts back up under the trees to eat, and the sound of the water follows you all night.
Hour by hour
Cold rock pools in the morning, a gorge walk, a swim in the sea and warm water at night. Here is how we would spend a day here.
Start slowly, with breakfast on a terrace in the shade and the sound of the stream.

Walk up from the village to the waterfalls and green rock pools of Gria Vathra and swim before the crowds arrive.

Stop on the way down for a long lunch in the shade of plane, walnut and chestnut trees.

Drive a few kilometres east to the Fonias bridge and walk up the gorge to the first waterfall and its round pool, then swim in the sea at the river mouth.

Ask what came in that day and have it grilled with oregano, olive oil and lemon, at a table under the plane trees by the harbour road.

End the day sitting in the warm open-air pools under the trees, with the stars overhead.

Waterfalls and rock pools in the forest just above the village, the easiest vathres on the island to reach.

The island's most famous waterfalls, a few kilometres east, a short walk from the bridge on the coast road.

Fengari, the summit of the island, a long day's climb from the edge of the village.

Good to know
Therma is on the north-coast road, about a quarter of an hour's drive east of Kamariotissa past Paleopoli. Buses run from the port several times a day in summer. Parking under the trees is easy outside August; in high season, come early to Gria Vathra and the Fonias bridge.
May and June are the best months for the waterfalls, when the rivers are full and the forest is bright green. July and August are busy and lively. September is warm and calmer, and the pools are at their lowest. Many tavernas and rooms close from October to May.
