Loch Morlich is a beautiful and romantic setting. Couples do get married on the beach. These tend to be small, and mainly informal ceremonies.
Loch Morlich Watersports is an activity centre. The business does not cater for weddings or offer any wedding services or facilities.
If you are planning to get married on the beach then you need to inform Forestry and Land Scotland. They have guidelines for such events and more importantly, a calendar to ensure that there are not multiple ceremonies on the same date/time and that weddings do not clash with other events.
The forestry commission contact is Emma Alsford, her email is email@example.com.
Loch Morlich Watersports hope that this information is of use, and all the best with your wedding plans.
