Top Things to Do

Trek Through the 'Canyon des Makis'

Embark on a guided trek through the dramatic sandstone canyons, often referred to as the 'Canyon of Lemurs.' Keep your eyes peeled for ring-tailed lemurs leaping through the trees and listen for the calls of endemic birds. Opt for a morning hike to avoid the midday heat and capture the best light for photography.

Sunrise Dip in the Piscine Naturelle

Wake before dawn to reach the 'Natural Pool,' a stunning oasis nestled within the rocks. As the sun crests the sandstone formations, the water glows with an ethereal light, offering a magical and refreshing swim. Go with a local guide who knows the safest access points and can point out unique flora.

Discover the 'Piste des Singes' (Monkey Trail)

Venture off the most beaten paths to explore the 'Monkey Trail,' a less-trafficked route that offers intimate encounters with various lemur species. The silence here is profound, broken only by the rustling leaves and the chatter of primates. This trail is ideal for those seeking a more secluded wildlife experience.

Picnic Lunch with Bara Cuisine

Arrange for a traditional Bara picnic lunch, prepared by a local family. Savor simple yet flavorful dishes featuring rice, zebu meat, and local vegetables, enjoyed amidst the breathtaking landscapes. This is a fantastic way to connect with the local culture and support the community.

Essential Travel Tips

packing

Pack light, but pack smart for Isalo. Think breathable, quick-drying fabrics for the heat and humidity, and definitely bring a good quality headlamp – you'll need it for navigating your lodge or campsite after dark, as electricity can be sporadic. Don't forget a reusable water bottle; staying hydrated is key, and you can often refill it at your accommodation.

money

While ATMs are scarce outside of larger towns, carry enough Malagasy Ariary (MGA) for your time in Isalo. Many lodges and guides prefer cash, and it's essential for smaller purchases at local markets or roadside stalls. Negotiate prices respectfully for souvenirs, but remember that a few extra Ariary can make a big difference to local artisans.

transport

Getting to Isalo often involves a combination of flights to Antananarivo (TNR) and then a domestic flight to Toliara (TLE) or Fianarantsoa (FMS), followed by a taxi-brousse (shared taxi) or private car. For exploring the park itself, hiring a local guide is mandatory and highly recommended for safety and navigation; they can often arrange transport from nearby towns like Ranohira.

safety

Stay aware of your surroundings, especially when hiking. While Isalo is generally safe, it's wise to hike with a guide who knows the terrain and can point out potential hazards like slippery rocks or sudden drops. Always inform your accommodation of your hiking plans and expected return time.

culture

The Bara people, who are indigenous to this region, have a deep spiritual connection to the land. When visiting villages or interacting with locals, a simple 'Salama' (hello) and a smile go a long way. It's considered polite to ask permission before taking photos of people, and a small tip is appreciated if you do.

food

Embrace the local cuisine! You'll likely find delicious rice dishes, zebu (local cattle) stews, and fresh tropical fruits. Try 'Romazava,' a flavorful meat and vegetable soup. If you're concerned about food safety, stick to well-cooked meals and bottled or purified water, especially when eating at smaller roadside eateries.

💡 Travel Tip: If you're planning your trip, it's worth checking flight prices on Trip.com before you decide.

Getting Around Isalo National Park, Madagascar

Rental Car with Driver

This is by far the most comfortable and flexible way to explore Isalo and its surroundings. You'll have a dedicated driver who knows the local roads and can adapt to your schedule, making spontaneous stops for photos or local markets easy.

Cost:Approximately $50-$100 USD per day, depending on the vehicle and duration. This usually includes the driver's fee and fuel.

Tip:Book well in advance through your hotel or a reputable local agency. Don't be afraid to negotiate slightly, but be fair. Common mistake: Not clarifying what's included (e.g., driver's meals, accommodation if staying overnight). Always agree on the itinerary and potential detours beforehand. Tipping the driver is customary (around 10-15% of the total cost).

Shared Taxis (Taxi-Brousse)

These are the local workhorses for inter-city travel. They operate on fixed routes and depart when full, connecting towns like Fianarantsoa and Ranohira (the gateway to Isalo). It's a budget-friendly way to experience local life.

Cost:Very affordable, typically under $10 USD for a long journey. Prices are usually per person.

Tip:Be prepared for a less comfortable ride and potentially long waiting times for departure. Arrive early at the station to secure a good seat (front is best). Common mistake: Expecting punctuality; 'when full' is the only schedule. Learn a few basic Malagasy phrases – it goes a long way with drivers and fellow passengers. Keep your valuables secure and be aware of your surroundings.

Private Taxi (for shorter distances)

For getting from Ranohira village to the park entrance or specific trailheads within the park's vicinity, a private taxi is a convenient option. These are usually 4x4 vehicles, essential for some of the rougher tracks.

Cost:Negotiate per trip, expect around $15-$30 USD for a round trip to the park entrance and back, depending on the distance and waiting time.

Tip:Arrange through your guesthouse or hotel in Ranohira. Always agree on the price *before* you get in. Common mistake: Not confirming if the driver will wait for you. Clarify if the driver is familiar with the specific trailheads you want to access.

Motorcycle Taxis (Motos)

In towns like Ranohira, motos are a quick and agile way to get around for very short distances, like from your accommodation to a local restaurant or small shop. They are not suitable for reaching the park itself.

Cost:Very cheap, usually $1-$3 USD for a short ride within the village.

Tip:Always wear the provided helmet, even if it looks worn. Agree on the price beforehand. Common mistake: Overestimating their speed or comfort for longer journeys. These are best for navigating the immediate village area.

Walking/Hiking

Once inside Isalo National Park, your primary mode of transport will be your own two feet. The park offers a network of well-marked trails leading to stunning canyons, natural pools, and viewpoints.

Cost:Included in the park entrance fee (around $15-$20 USD per person for 24 hours).

Tip:Hire a local guide at the park entrance – it's mandatory for most trails and highly recommended for safety and enriching your experience. Guides can spot wildlife and explain the local flora and geology. Common mistake: Underestimating the heat and sun exposure; carry plenty of water, wear a hat, and use sunscreen. Start hikes early in the morning to avoid the midday heat.
