Summer (June-August) gives you stable weather and long daylight for hiking and kayaking, though expect crowds. Winter (November-March) opens up snowmobiling and ice cave tours, but conditions are unpredictable - book flexible cancellation policies and check forecasts religiously. Spring and autumn are quieter sweet spots if you're comfortable with variable conditions.

Popular private Snaefellsnes tours and snowmobiling excursions fill weeks in advance during peak season. Book 2-4 weeks out if you're traveling June-August; winter tours are more flexible but weather cancellations happen, so confirm a few days before departure.

Most Snaefellsnes excursions cover transport, a driver-guide, and stops at 3-5 key sites (Kirkjufell, black sand beaches, basalt cliffs). Glacier and hot springs combos add entrance fees and equipment. Check before you go - some tours are pick-up only, others all-inclusive.

Waterproof layers, thermal base layers, sturdy hiking boots, and wool socks - you'll be outside for 6-8 hours in wind and spray. Snowmobiling and ice cave tours require additional gear; check if the operator provides it or you need to rent separately.
