Camping at Thingvellir National Park offers a cozy spot to pitch your tent or park your camper van amidst stunning Icelandic landscapes. Open during the summer months, with some sites available until November, visitors can enjoy facilities like restrooms, showers (weather permitting), and even electricity at Nyrdri-Leirar. Payment can be made at the Service center, and discounts are available for groups of 10 or more. Just remember, reservations aren't possible, so it's first-come, first-served for a nature-filled getaway in this UNESCO World Heritage Site.
