We stayed at the HF Holiday's House Alltshellach, https://www.hfholidays.co.uk/country-houses/locations/glen-coe-scottish-highlands, which is across Loch Leven from the village of Glen Coe. They have guided and self-guided multi-day hikes but if there are extra rooms they do rent out for a night or two. I don't know how ambitious your are or how much time you have but from Kinlochleven, just up the road from Altshellach, you can pick up a portion of the West Highland Way. You follow the West Highland Way but bare off past a couple of stalking lodges and connect to the old military road then scramble down to a cute little waterfall. It's about a half day hike. Or you just walk up to the waterfall and back. Then you can ice climb at the largest indoor ice wall, https://www.ice-factor.co.uk/adventures/indoor-ice-climbing/.
Edit: From the village of Glen Coe there are a couple of very short, very easy walks. You can also hike/walk around Inchree Falls.
