Due to gusty wind yesterday we went for walk en famille to Almondell (except the no 2 child who spent all dy inside Laser Quest - 2 parties on same day).

The Almond is a deep wide gorge at this section of its route so you are out of the wind. The park is either side of the river twixt Mid Calder and Broxburn. A network of tarmac and off road walking routes. As there is nobody there the cyclists have plenty space. Couple of people checking it out on mountain bikes and one young couple on tourers with the bloke carrying two well laden red ortlieb panniers. It is part of Route 75 so they may have been passing through. There is a little visitor centre selling ice cream/teas to take away and bric - a -brac.
I wouldn't go in winter as I have used it occasionally when I was starting out to cycle off road to Livingston in autumn/winter - when sun lower in sky - damp and gloomy. Also dependent on wind direction and if weekday the water treatment place at MidCalder can intrude. The site has many mill lade type water channels so may have been industrial but also remains of walled garden and features suggesting Lord Livingston Estate or somesuch. The river has excellent stepping stones but swimming I would avoid as the local livingston Asda Trolley River Race ends in the park. Close by Jupiter Sculpture Park and Veitch's Nursery [best tended plants and shrubs for sale in Edinburgh area].
