Able Trek offers fully staffed and assisted tours for adults with mild to moderate developmental disabilities. Travelers must exhibit appropriate social behavior, have no major medical concerns, be at least 18 years old and display appropriate behavior toward property, themselves, and others. The typical Staff to Traveler ratio is 1:3 or 1:4. If a Traveler requires more assistance and/or supervision, we may require the guest to attend the tour with their own 1:1 support staff.
