Tips for Visiting Terwilliger Hot Springs in Oregon
Arrive at Terwilliger Hot Springs in the early hours of the morning, which is the quietest and usually the best time for soaking.
Dress up in layers because you’ll come across varying temperatures throughout the trip. So be prepared, and if you don’t want to wear too many jackets, at least keep them with you.
Put on a lot of sunscreen and wear a hat as well.
Soaking is good for you, but don’t do it for prolonged periods, especially under the hot afternoon sun. Do take breaks in between.
Should you take a break from soaking, rest under a cool tree.
The elevated location, daytime temperatures and the hot pools can dehydrate you. Drink plenty of water, especially if you’re visiting the springs in the summer season; this is probably the best tip that we have for you. Ideally, you should take a plastic refillable water bottle with you, which you can refill at the bathhouse.
Avoid drinking caffeine and alcohol during your trip.
Though the waters of hot springs are usually rich in minerals and healthy for your body, they can tarnish your jewelry and may even stain your swimsuit. So avoid wearing new outfits and leave all the extra accessories at home.
