What to Expect

Activity Level 3

In order to make the most of what this expedition has to offer, the trip will be active, requiring you to be in good health and physical condition. The schedule will include long days, with some early departures, and activities scheduled throughout the day and into the evening.

Daily excursions can require up to three hours of walking, often over loose rocks and uneven terrain where stairs are unavailable or do not have handrails, and standing, often in the warm sun. Rafting down class II/III rapids on the Balsa River is appropriate for kids 8 and older. The degree of difficulty for each day’s activity will be described in daily briefings. Activities will run rain or shine.

This promises to be a memorable journey, but as with all travel, a flexible attitude, a spirit of adventure and a willingness to explore new areas will enhance your enjoyment of this program. You do not have to participate in all the scheduled activities, except when traveling to the next destination. We are sure you will be pleased with the exciting educational program provided, but we want you to be aware of the pace and activity level.
