There is a visitors centre at Drumnadrochit which has an exhibition and is overlooking the loch. There are also various boat tours on the loch itself for those that are brave enough to risk the wrath of Nessie!
Urqhart Castle is probably one of the most photographed in Scotland and would make a great spot to look at the loch. The castle is atmospheric and beautiful.
The A82 which runs up the west side of the loch is a very busy road, especially in the summer, and its not that big, so be prepared to get stuck behind tourists, busses, caravans etc. There are places to pull up and park so you can admire the views.
The roads on the east side of the loch are even smaller, but are less travelled - used more by locals. I dont know if there are any parking places though as we always use the A82.
Other places locally that you may like are Fort Augustus - which is one of three "Forts" in the area with the others being Fort William and Fort George. Glenmoriston is a lovely drive and worth the detour. And of course, you have the Caledonian Canal which is amazing. over 7 years ago
