Read the two destination guides, then choose the place whose ordinary evening sounds better—not just the one with the longer attraction list.
Boulder: Start exposed foothill hikes early, particularly in warm months when afternoon thunderstorms are a real planning issue. Use the official seasonal Park-to-Park shuttle for Chautauqua on summer weekends rather than building the day around limited parking.
