Summertime in Washington, D.C. is always very humid and hot so any activity that includes time indoors (with air conditioning) is a must. That being said, I’ve enjoyed the Hillwood Estate, Museum and Gardens during all four seasons.
This grand estate is tucked away in the Northwest corner of Washington, D.C. Ranked on Trip Advisor’s Top 30 Attractions in Washington, D.C., this hidden gem is underrated. If you live in the area and you haven’t spent an afternoon exploring the museum and gardens, take a taxi here (from the Van Ness metro) as soon as you have some free time.
As you wander around the gardens, you would never know that you’re inside a city. You’re not allowed to take pictures inside the museum, but it’s well worth the $18 suggested donation. Stop by anytime on a Saturday or Sunday from 10am – 5pm. I suggest giving yourself some extra time to relax or meditate in the gardens, if it’s not too hot.
