Wigwams are great and you should find availability midweek for July, but less likely at the weekends in popular areas.
Have a look for some Mongolian yurts too, they’re great.
Loch Tay is a good base, and close to you. Plenty of walking in the area and you can hire boats to go out on the loch (with fishing rods too!). A great way to spend the day and no doubt a real adventure for an 8 year old.
There’s a guy based on the loch tay marina site (where they have lots of different type of accomm, form wigwams, to yurts to proper cabins) who organises lots of different activities (biking, archery etc).
Definitely a good base with plenty to keep you busy for 2 or 3 days.
globalti – thanks for posting that, you’ve just reminded me i’m catching a 10pm crossing to Coruisk on Friday night (MC weekend away). Dubh’s Ridge on Saturday if it stays dry!
