Path Around Lake Saint Ana

Highlight • Trail

Anyone visiting Lake Sfânta Ana doesn't need meteorologists to predict the weather. They have an empirically proven method at their disposal, provided by the volcano itself: two cracks in the mountain that predict the weather. Locals know: "If the fumes from the cracks burn your nose, it's a sign of a thunderstorm. If not, it will be a sunny day, perfect for hiking."

Saint Anne Chapel

Highlight • Religious Site

The Chapel of St. Anne was first documented in 1349. The original chapel was made of wood. Legend has it that the small church was destroyed during both the Tatar and Turkish invasions. Its restoration was documented in 1562. Between 1562 and 1764, two annual festivals were celebrated: St. Anne's Day and the Feast of the Nativity of the Virgin Mary. Up to 30,000 pilgrims came to the Feast of St. Anne. The chapel was badly damaged during the First World War and was demolished and rebuilt in 1927. Nothing remains of the nearby St. Joachim Chapel, built in 1562.

Tinovul Mohoș Boardwalk Trail

Highlight (Segment) • Trail

A wooden jetty leads through the nature reserve. Sometimes they are just single posts. The way may only be visited with a guide - what I have learned afterwards. However, the leadership is only in Romanian.

Lake Sfânta Ana

Highlight • Lake

Saint Ana Lake in the Ciomatului Mare crater is the only lake of volcanic origin in Central and Eastern Europe and the most visited tourist attraction in Szeklerland.
It is surrounded by the steep walls of the volcanic cone of Monte Ciomat, with several higher peaks: Ciomatul Mare (1301 m), Ciomatul Mic (1238 m), Tata Hill (1174 m) or Piscul Pietros (1125 m).
The lake, unique in Europe, is located at an altitude of 946 m, has a diameter of 1737 m and a greatest depth of 7 m.
From the crater rim, 13 temporary streams formed after the rains carry water and gravel into the lake. The lake is fed by rainwater and water from snowmelt.
The lake's sedimentation process began at the northern and western edges, with the lake floor being covered by an increasingly thick layer of mud. The lake is currently 6.5 m deep at its deepest point.
In good weather, especially without wind, you can see gas bubbles rising from the bottom of the lake, which are actually an expression of post-volcanic activity. In the northern, northeastern part of the lake, you can see a layer of floating peat about a meter thick.

Mohos Peat Bog

Highlight • Natural Monument

Only cordoned off with a thin tape, I would doubt the video surveillance sign - but you can't just march through because then you'll probably meet a guided tour. Ditto from the rear entrance (it only says “entry prohibited” in Romanian). Apparently there are also English tours every now and then. So just be there at one of the times in the photo and see what happens.

When arriving at the lake, make sure to start circumnavigating it in a counter-clockwise fashion, to make sure that the rewarding coffee and pastry hut is at the end of your walk…

In August 2023, a ranger was on duty who spoke very good English - but the (free) tour soon had to be broken off: a bear had been wounded in a turf war and was therefore unpredictable. So I wouldn't recommend the route from the north through the moor.

A wooden pier leads through the moor with beautiful views over small moorland lakes and the enchanted plant world. Guided tours of the moor are regularly offered. Unfortunately only in Romanian language. Still highly recommended.

A nice narrow path hugs the bank of the almost circular mountain lake. While on the eastern shore, the stalls take care of the physical well-being of the visitors and there is even a boat rental, the western shore is very quiet. A circumnavigation on this Uferweg is very worthwhile. Attention: Please do not feed bears :-)
