Hi Pete
Urquart Bay is a good easy stop for berthing. There's shore power for which you buy a ticket in a car park type machine. Also water there. Nice & sheltered if the weather is poor. The walk to Drumnadrochit is along a busy road, but safe enough if you watch out for yourselves. The Loch Ness Monster Museum just before you get into the village is well worth a visit. It also has a very good gift shop & a Whisky shop too. The afternoon that we get to Urquart, we like to tie-up at the castle moorings & visit the castle. You still need to pay & tie up on the side they ask you to (I think it's the starboard side). Plus point is that it's fun tying up inside the grounds, minus point is that you don't get much time before they close. Nice gift shop. Urquart Castle number is 01456 450551. We aim to get there just after 4pm, then have about 1.5 hours to wander around. It's not that big, but very good for some wide angle shots of Loch Ness.
Bear in mind Foyers, half way along Lock Ness to port. Lovely woodland walk, squirrels & a great waterfall. See the top & bottom of the falls. You need permission from Caley to berth there as it's difficult in winds. PM me your email & I can send you a map.
Fort Augustus is nice, you can spend a day there. Good food shopping to be had to the starboard side & over a bridge. Look for a petrol station - it's in there. Also a cute little animal rescue place tucked up the side of it. Cheap entry fee, slightly scruffy, but worth a quick visit & giving the lady who runs it a few pounds to look after the mostly rescue & orphaned animals. Long lens for some red deer perhaps. Very good fish & chips on the port side further up the locks. A good butcher along there too - port side.
You missed Kytra, our favourite place. Lovely walks around there & generally very quiet. Walk off the path towards River Oich. No water, but shore power on the pontoon on the far side of the lock.
Watch out for the lovely little houseboat near the Well of 3 heads at Loch Oich. You can berth nearby for photos.
Laggan, we've done.
Gairlochy is our 2nd favourite berthing. Red deer on the towpath late evening, Maybe otters too. No water. Shore power on the side you get to first. We like to wild camp on the far side of the locks. Good views of Ben Nevis.
On the way to Banavie, take some shots of Moy bridge. Very short pontoons at each side for a quick tie-up for photos. Difficult tie-up for newbies.
Banavie has water & shore power. Apart from Neptune's staircase, nothing much to see there really.
I generally take a bag of £1 coins to pay for shore power.
Good luck!
