Discover Mars: Observatory, Hiking and Mountain Biking

When looking for a hotel in Mars, it helps to first decide what you would like to focus on during your outing. The places and activities mentioned differ in terms of access, landscape, local history and scheduling. This lets you plan your stay around a specific visit or activity rather than choosing based only on a general travel theme.

Visit to the observatory

Planète Mars – Observatoire Hubert Reeves is open to the public, depending on the programme, and especially by reservation. If you are planning your visit in advance, check the relevant programme and confirm whether a reservation is required. This allows you to take the visiting conditions into account when planning your trip.

Volcanic landscape and local history

Montréal is one of the municipality of Mars's two volcanic enclaves; it is home to large, prismatically structured lava formations. The names help clarify the geography: Montréal refers to the enclave, while Mars refers to the municipality. The hamlet of Saint-Romain-le-Désert offers another connection to local history. It was once the main settlement and has a parish church. While Montréal is associated with the volcanic lava formations, Saint-Romain-le-Désert is known for the hamlet's former role and its church. It is also helpful to distinguish between the place names for orientation: Montréal is an enclave within the municipality of Mars, while Mars refers to the village where the loop starts. This helps distinguish the description of the landscape from the starting point; here, the same name refers to two different geographical levels.

Hiking with Planète Rouge

Planète Rouge offers a hike open to everyone on the second Wednesday of each month. Check the date again before your trip. Depending on the outing, the hike may be offered as a full-day or half-day trip; the format varies. So when planning your time, consider both the monthly date and the format of the specific outing. The hike ends with a convivial get-together at the shop. Take this into account when planning.

Mountain bike loop across the plateau

The L’Observatoire - VTT FFC N°26 Bleu loop is 13.7 kilometres long and moderately difficult. It crosses a plateau. The route starts in the village of Mars; the start and finish are at the campsite in Mars. Check local trail conditions before setting out. The distance, difficulty level and terrain describe different aspects of the route: its length, its stated level of difficulty and its course across the plateau. Hiking and mountain biking involve different planning considerations: for the hike, the format varies from half a day to a full day; for the bike ride, distance and difficulty level matter. This lets you compare a time estimate with route characteristics rather than with a shared duration. The plateau adds to the picture of the terrain.
