- Families building summer plans with waterparks and rainy-day backups

Top 5 May Highlights
1. Scenic drives: May’s best trip “glue”
May is a sweet spot for scenic drives: longer daylight makes it easier to build in pull-offs, short walks, and detours. Without feeling rushed. It’s also one of the simplest ways to connect iconic stops with smaller communities and viewpoints.
Good to know: If you’re mixing “Hills and Badlands,” plan your days around driving loops to avoid backtracking.
Recommended place to check out: If you’d rather let someone else handle logistics and timing, Mount Rushmore Tours is an easy way to add a guided day into your plan.
2. Hiking season ramps up (choose your mileage)
More trails and higher-elevation areas start becoming better options in May, and longer days mean you can pace your hikes without squeezing everything into a narrow window.
Good to know: Conditions can still vary. Pack layers, plan for wind, and start earlier in the day if you’re aiming for longer hikes.
Recommended place to check out: For a guided, local-expertise approach, Black Hills Adventure Tours can help take the guesswork out of “which trail is right today.”
3. Camping & RV in May: season kickoff (with smart expectations)
May is when camping energy really starts to build. Especially heading into Memorial Day Weekend. It’s a great month for travelers who want campfire nights and early-season space, but it’s also when planning matters most.
Good to know: Nights can still be cool, and weekends book faster than people expect. Especially later in May.
Recommended place to check out: Gold Valley Camp is a solid option to consider if you’re looking for a camp-style base and want to get ahead of high season demand.
4. Family fun “easy mode”: waterparks and rainy-day backups
May is a planning month for families. And having one weather-proof “we can do this no matter what” option makes trip decisions easier. Waterparks (and nearby indoor attractions) are perfect for early season confidence and Memorial Day Weekend planning.
Good to know: Even if your trip is outdoor-first, one indoor anchor can save the whole day if weather flips.
Recommended place to check out: Watiki Indoor Waterpark Resort is a strong pick when you want built-in family fun and a reliable backup plan.
5. Water season begins (boating/kayaking and state recreation areas)
May is the start of “let’s get on the water” season. Especially for travelers who want a change of pace between hikes and drives.
Good to know: Water temperatures can still be cold. Dress for it, watch wind, and prioritize safety.
