Put the Tenerife weekend after the study week
Coast, La Laguna, Teide surroundings and island towns have very different weather and altitude. Fix classes, coursework and rest first; select one activity whose distance, opening status and weather fit rather than turning a weekend into a checklist.
One adaptable culture route
Choose one theme—historic town, coast, or a Teide-area activity permitted by current conditions—rather than long island crossings in one day.
Travel and return
Use TITSA information for transfers and last buses; carry a communications and return fallback for remote nature.
Weather, nature and safety
Manage sea conditions and sun on the coast, altitude and temperature change inland, and protected-area rules everywhere.
Four checks before leaving
Confirm official opening or reservation status, real return transport, weather or sea conditions, and companions plus emergency contacts. Current operator and venue notices govern access, timing and safety.
