About this event

The GR52 is the wilder sibling of the famous GR5, cutting through the most rugged heart of the Mercantour National Park before dropping to the Mediterranean at Menton. Over nine days we cross the park from the alpine interior to the sea, taking in the Vallee des Merveilles - an open-air Bronze Age gallery of more than 40,000 rock engravings around the sacred slopes of Mont Bego.

We begin gently. Three warm-up days based in Nice and Saint-Martin-Vesubie let the group acclimatise, shake down gear and get the legs working at altitude before the main event. From there we walk the classic GR52 traverse: six days point to point from Saint-Dalmas-de-Valdeblore to Menton, crossing a series of high passes above 2,400m, threading past turquoise glacial lakes, and finishing with a long descent through olive groves to the Riviera coast.

This is a serious high-mountain route with roughly 5,000m of cumulative ascent and several exposed passes. It rewards hikers who arrive fit, sure-footed and comfortable with long days on rocky ground - but it asks no technical climbing skills. Nights are spent in mountain refuges and village gites, with hearty half-board meals along the way. If you want one trek that captures the full drama of the Maritime Alps, this is it.

Important notes

  • Trip: 14-22 July 2027, nine days, Nice / Mercantour / Menton. Difficulty 4 (very challenging). Group capacity 6
  • DAY 1 - Arrive Nice. Settle in, gear check, group dinner on the Riviera. Transfer up to Saint-Martin-Vesubie (975m), gateway to the Mercantour
  • DAY 2 - Acclimatisation walk from Saint-Martin-Vesubie: the Lacs de Prals circuit (approx 4 hours) through flowery pastures to a cluster of alpine tarns. An easy day to loosen the legs at altitude
  • DAY 3 - Second acclimatisation walk in the Boreon valley to Lac de Trecolpas (moderate), through forest and mountain streams, chamois country. Optional visit to the Alpha wolf park. Transfer to the trailhead at Saint-Dalmas-de-Valdeblore
  • DAY 4 - GR52 begins. Saint-Dalmas-de-Valdeblore towards the high country, climbing steadily into the park
  • DAY 5 - Over the high passes towards the Refuge de Nice, past glacier-polished rock and alpine lakes
  • DAY 6 - The shortest but demanding stage over the Baisse du Basto (2,693m, the high point of the GR52), descending into the Vallee des Merveilles. Refuge des Merveilles on the shore of Lac Long Superieur
  • DAY 7 - Explore the rock engravings around Mont Bego, then continue south following the old Italian border, with far-reaching views
  • DAY 8 - The landscape shifts from alpine to Mediterranean; a long descent begins towards the coast
  • DAY 9 - Final stage down through maquis and olive groves to finish at Menton on the sea. Onward travel by train from Menton to Nice
  • Rafick leads to control the pace of the group; please do not go ahead. We are in no rush to finish. This trip is open to hikers of reasonable fitness who can sustain days at altitudes approaching 3,000m. New members are encouraged to join a few NZ hikes beforehand

Safety

  • The GR52 crosses several exposed high passes; weather in the Maritime Alps changes quickly and afternoon storms are common
  • Warm and waterproof layers are essential even in July
  • Snow can linger on north-facing slopes into early summer
  • Comprehensive travel insurance covering multi-day hiking above 2,500m is mandatory
  • Do not throw food waste on the trail; the Vallee des Merveilles is a protected historical monument with strict rules (no camping, no dogs, no marking of rocks)
