This place is Allt Bronach. It's in Balgowan, which is in the Cairngorms National Park, but right on the western edge. It looks out over Gaskbeg Farm and the valley.
It's a two bedroom cottage, sleeps four. You can have it as two doubles or a double and two singles. There's one bathroom, it's a wet room. There's underfloor heating everywhere so it's always warm. The garden is enclosed, so it's private. It's quiet out there.
The kitchen has what you'd need: dishwasher, washing machine, microwave. There's a separate dining room and then the sitting room. All the bedding and towels are here, and the Wi-Fi is included.
You can walk straight out from the back door. The Laggan Wolftrax mountain bike centre is basically next door. Aviemore is about 40 minutes east, Fort William is about 40 minutes west. So you're right in between them.
For other things to do, the Cairngorms National Park site has the details on walking and wildlife. The Forestry and Land Scotland page covers Glenmore and other forest walks nearby.
Parking is right outside. No pets, I'm afraid.
