Provincetown MA (eastern side on the ocean) and North Hampton MA (western side in a valley near the mountains) are both some of the most LGBTQ friendly places in the US. They are both insanely fun. I've lived in both throughout my life and I visit both often. They both have a great night life, restaurants, music, & theater scene. They both have bike trails and lots of dogs. North Hampton is more affordable but Provincetown is surrounded by beautiful beaches. You can't go wrong with either. If you need something more affordable I recommend one of the surrounding towns for either (Hadley or Amherst near North Hampton and Eastham Wellfleet or Truro near Provincetown).
