Þakgil can be visited in daytime or used as a seasonal base for the surrounding trails.
The operator lists camping, cabins, toilets and showers, with a cave serving as the common dining shelter. Availability, prices and opening dates can change, so confirm those details directly if the visit depends on them. Accommodation inventory is not a permanent place fact.
Day visitors still need enough time for the gravel journey in and out plus the chosen walk. An overnight can create more margin, but it does not make weather, access or trail checks optional. Match the visit to a named trail and the conditions at the time.
