Winter vs Summer

Winter Character

  • Ice curtains near skylights
  • Low sun angles → dramatic light shafts
  • Colder footing; bring spikes if suggested

Snow at skylight rim

Summer Character

  • Moss around entrances; brighter skylights
  • More stable footing
  • Great for families and first‑timers

Recommendation

If you’re after photography, choose winter mornings. For comfort and pace, choose summer afternoons.
