Answer: Short answer: yes — The Inn at Death Valley and the Furnace Creek area are excellent places for dark-sky astro photography in late May, and there are several reputable instructors and multi-day workshops that run in/near the park. Daytime temperatures at the end of May are usually warm but not yet the extreme highs of summer; you’ll want to avoid strenuous daytime hikes during the hottest mid-afternoon hours and take standard desert safety precautions. You will not need to leave the park to eat — The Inn and nearby Oasis properties offer dining, plus a few other casual options in the Furnace Creek area.
