We hike/travel all over Colorado. As others have said April in the high country is still snow season and snow storms are not uncommon - some can be big too. With that being said I would head to the Western Slope. The elevation is lower than most of the state and you are more likely to have warmer weather. The Colorado National Monument in Grand Junction is spectacular.
https://www.nps.gov/colm/index.htm It is the Sedona of Colorado. Many, many hiking options. I would search YouTube for Grand Junction hikes. There are other options on the BLM lands all around the area.
Just to the east of Grand Junction is Palisade which is Colorado’s wine and fruit region. I think there are 24 wineries to explore and hiking options with petroglyphs nearby.

There are all levels of hotels in Grand Junction. Check out the Grand Mesa when you are there. You’ll hit snow, but it is the world’s largest flattop mountain. Remote and beautiful. Maybe a day of snowshoeing there could be fun.

Good restaurants in GJ are Bin 707, 626 on Rood and Il Bistro Italiano.
Let me know if you have questions. We have been all over the state and to many places most folks never heard of. Lots and lots to see and do in Colorado.
