Absolutely, here are some travel tips for your trip to Simferopol, Sevastopol, Yalta, and Kerch in Crimea:

Best Time to Visit:
The ideal time to visit is during the spring (April-June) and the early autumn (September-October). Summer can be very hot and crowded with tourists.

Route and Accessibility:
The most common way to reach Crimea is by air via Simferopol International Airport. From Simferopol, you can travel by road to Sevastopol, Yalta, and Kerch. Local buses and trains are available but might be crowded in peak season.

Altitude and Acclimatization:
These locations are not at high altitudes, so, acclimatization is usually not an issue. But do take it easy for the first day or two, especially if you have flown a long distance.

Accommodation and Booking:
Hotels, guesthouses, and vacation rentals are available in all four cities. It's recommended to book accommodations in advance, especially if you're travelling during the peak season.

Clothing and Essentials:
It can get chilly in the evenings, so bring sweaters or light jackets. Crimea is famous for its beaches, so don't forget to pack your swimsuit, sunblock, and beach accessories. Comfortable walking shoes are a must as there are many scenic walks and historical sites to explore.

Health and Safety:
Carry a basic first aid kit and any personal medications as some specific medicines may not be readily available. Drink bottled water and avoid street food if you have a sensitive stomach.

Local Etiquette and Respect:
Russians form a large part of the population in Crimea, so learning a few phrases in Russian will be helpful. Respect local customs and traditions especially when visiting religious and historical monuments.

Remember to check for any travel advisories or restrictions before you plan your trip to these destinations.
