I slipped and fell on the treacherous streets of NYC over the weekend and have spent the last few days applying ice to the beautiful black eye that has shifting colors ever since. But I'm back now.
I have done a number of hikes on the west coast and I do love the Ullapool area. As my walking group would always say, "West is Best!" There are some very easy walks in the hills above Ullapool as has mentioned. You can walk up to the top of Ullapool Hill for some gorgeous views. This is an easy walk. The website makes some additional suggestions. We did a "bog walk" near Stac Polly, but I can't find a reference to it.
Just up the road are the Inverewe Gardens. No hiking per se, but a nice place to visit.
South of Ullapool there are some nice walks near Loch Maree. Have you found the Walk Highlands website? Here's the link to the Ullapool area.
Inland a bit is Glen Affric if you want to try something in a glen. The first time I went we walked around the Loch. The north side is quite rocky, but it was a gorgeous hike in a beautiful glen.
We did this walk in Torridon and it was very nice. There's another walk right near there that I can't find right now, that took us a bit up into the hills. I'll have to consult with a friend if you are interested.
I have never done and Applecross walks as we were based near Inverness and my friend had decided that we would have to get up too doggone early to enjoy the hike and there plenty closer. But you might want to investigate the area. I did a car trip and it is gorgeous.
BTW how are you defining heavy-duty hiking gear? I would really recommend decent water proof boots. The paths can get very boggy. Also, I finally gave in and got rain pants. They are light weight and I am much happier walking in Scotland with them. Finally, do usually have a midgie hat-- basically, mosquito netting with a very fine mesh that can govern my hat. It has made some walks quite nice when they might have been unbearable otherwise. I also do have a backpack cover for my day pack. I am sure that you have a good waterproof jacket.
