How to get to Thingvellir National Park
There are several roads leading to Thingvellir National Park which is located approximately 45 km northeast of Reykjavík.
Take road no. 1 heading north out of Reykjavík. After driving through the town Mosfellsbær take the first exit to the right at roundabout onto road no. 36 to Thingvellir. This route follows the main road to Thingvellir and is ploughed most days during the winter.
Another option in summertime out of Reykjavik is to take road 1 towards Hveragerdi/Selfoss on the south coast. Just after leaving the Reykjavik city limits turn left onto road 431 and follow it onto road 435 (Nesjavallaleid). This road will follow the pipeline delivering hot water to Reykjavik from the Nesjavellir power plant in the Mt. Hengill area. The road crosses the Hengill volcano providing great views of Lake Thingvallavatn coming down from the mountain on the north side. When coming down the mountain turn left on road 360 (Grafningsvegur) and drive about 11 km along the banks of Lake Thingvallavatn until turning right onto road 36. Follow that about 8 km until reaching the visitor center at Thingvellir National Park at Hakid (Fraedslumidstod).
Note that this road (435) is closed in winter and only open from May-September depending on snow conditions. Make sure to check conditions before driving it.
