Best Time to Visit:
The best time to visit Slovakia is during the spring (April to June) and autumn (September and October) months, when the weather is pleasant, and the tourist crowd is relatively less. However, if you’re a winter sports enthusiast, you'll find the ski resorts in Nový Smokovec to be a paradise from December to March.

Route and Accessibility:
All of your destinations are well-connected by Slovakian public transport. You can take a bus or train to Modra from Bratislava. From Modra, Pezinok is a short bus ride away. For Stará Turá, you can take a train from Pezinok, and for reaching Nový Smokovec, there are regular trains from Stará Turá.

Accommodation and Booking:
There is a variety of accommodations available from budget to luxury hotels. It is advisable to book your accommodations in advance especially during the peak tourist seasons. Websites like Booking.com or Airbnb can provide multiple options.

Clothing and Essentials:
Make sure to check the weather forecast before your trip. Generally, it's a good idea to bring layers – lightweight clothing for the day and warmer items for the cool evenings. Don't forget comfortable shoes for walking and hiking, especially in Nový Smokovec.

Health and Safety:
Slovakia is generally a safe country for tourists. However, it's always advised to have travel insurance for unexpected incidents. If you are going for hiking or skiing, ensure to have all necessary safety equipment.
