Carl Nielsen If you are into light climbing and hiking, this place is very nice. There are two caves that you can crawl into to look at stalactites and several kinds of bats. You must bring a good headlamp, spare lamp, etc. yourself and it will be a good experience. There are still only very few tourists, so you can turn off the lights for 10 minutes. and experience total darkness and hear the bats.
Alain Leneveu Beautiful place, nice trek and 700m cave. Stunning view at sunset !
John 5 stars for the national park: amazing and really impressive views of the Tsingys. I actually preferred the Tsingys here over the very popular ones in Bemaraha. However we got unlucky with the guide. It looks like it's better to book a guide in advance as when we showed up in the morning asking for a wildlife expert, we got a random Joe who didn't even know the names of common bird species. Still very much worth it but guides are hit or miss.
Benjamin K We just had 5 hours so we were not able to see it all. But what we saw was great! If you are in the north of Madagascar and don't mind a long bumpy ride to the park, then please don't miss this beautiful park.
Tom theWildLife Great park to see the tsingy, some baobabs and the odd lemur. Though this is one of the most expensive park to get into in Madagascar at 65 000 ariary (2017) and in my opinion this is overpriced although the park is still very nice.
