Tips for Visiting Lough Melvin
- Remember the lake straddles the border between County Fermanagh (Northern Ireland) and County Leitrim (Republic of Ireland), so check which side you're launching from - fishing and access rules differ by jurisdiction and you may need a local permit.
- Lough Melvin is famous for its three trout types (including the locally endemic gillaroo and sonaghen); anglers and naturalists get the most out of guided local boat trips or licensed angling guides who know where the rare stocks concentrate.
- Use northern access points around Garrison and nearby public launch spots if you want quick water access and local services - that area is a common base for boat hire and guide operators.
