Logistics

Getting there & staying

Getting there	Short-haul to Reykjavík + 45 min drive. Fly to Reykjavík (KEF), then drive ~45 minutes to Þingvellir National Park. Easy add-on to any Iceland itinerary.
Where to stay	City base (day trip). Reykjavík as a base; Silfra is a half-day guided trip rather than a multi-day dive holiday.
Operator to look for	Dry-suit-certified guided operators only — entry is by platform into freezing water.
