We are travelling by car with 3 kids,13,12 and 10, love the outdoors but going in end July/Aug so cld be hot! Can you recommend a couple of good islands to stay on.? Somewhere to base ourselves for a week or 4 days as we will be tired of driving. Any tips on national parks? Not fan of big crowds. Wld like to incorporate a day or two of sailing if time permits. Any suggestions appreciated.
