There are a few things to consider on which time of day would be best for you, and it’s just a matter of preference. You would have the same exhilarating experience! The zipline tours start as early as 8:00 am and different Vendors have additional times, some go every half hour. The morning is generally a cooler time of day, if you don’t mind waking up early, and it leaves the rest of the day open for other adventures. Of course ‘beach time’ is always best in the morning, and in that case, the afternoon zip could also be perfect.
