>>1889404I was stargazing in Bristol yesterday. It's not the best, and photos definitely don't do it justice, but it's honestly not that hard.
Train to Ivybridge, hike to Piles Copse and just go stargazing up on one of the hills there.
Train to Plymouth, buses to Dousland, hike into the Burrator area and just disappear into the wilderness a couple miles to the east-north-east of there. Go stargazing up on a hill there. Bonus: explore the stone age ruins there
