The two days on this site
What each one covers, and what you are paying for
Two private days, 30 minutes and $110 apart, with different routes through the same coast.
Two listings drive the south-west, close enough in price that the choice is about shape rather than money.
The Private Southwest Chamarel Highlights Tour runs 7.5 hours at $122 and carries 2,030 reviews at 4.8 — the largest review count of any listing on this site. Its own description names what it covers: the Seven Coloured Earths, waterfalls, volcanic mountains, scenic viewpoints and sacred temples, with a private guide on a personalised route. Because it is private, the order of the day is yours to push around, which is the part people book it for.
The Private South-West Tour with Lunch runs 7 hours at $110 with 1,316 reviews at 4.8, and its listing names a longer string of stops along the south coast: Chamarel Waterfall, 7-Colored Earth, Alexandra Falls, Black River Valley, Grand Bassin and Trou aux Cerfs. A meal is listed as included. That is a fuller route and a shorter day, which is a real trade: more stops in less time means less standing around at each one.
Neither is a Chamarel waterfall Mauritius scenic flight. Both are road days, and the Chamarel waterfall Mauritius tropical forest is seen from the rim. A Chamarel waterfall Mauritius aerial perspective is a helicopter booking and a different budget: flights here begin at $860.
Both are private, and that decides the day for a lot of people. A Mauritius Chamarel waterfall family booking is not a coach, and a Mauritius Chamarel waterfall nature stop lasts as long as your group wants.
